ladies and gentlemen welcome thank you for coming for a talk from Alex Bebek and Adrienne Logan hi everyone I'm Alex babish and this is my partner agent Logan my business partner and today we're gonna be giving you a brief introduction into hydroponic systems in commercial facilities so before we start
we'll tell you a little bit about ourselves our company is called neuro vine we were based out of New York City or startup and around for about a year and a half and we're coming out with our first product it's a automated nutrient dosing a data collection machine and has a web application but don't worry we're not here to like sell you anything just kind of tell you a little bit about ourselves so one of our last things we
went into and in terms of like I started with like a little accelerator called the I Corps from the National Science Foundation it's where they give engineers and scientists money to go travel around the United States and do customer discovery and so for us we we went out and visited cannabis farms all over the country in Washington Oregon California of course in Nevada as well and so some of these really somebody's in in these interviews were super insightful for us so we wanted to share with you a little bit about what we learned and teach you a bit about hydroponics so to get started about
hydroponics we're gonna first start by talking about soil which most people are familiar with so first of all I'll provide a medium for the roots to grow into so the plant can stay upright and of course then we also the soil also
provides a lot of different nutrients the plant needs the nitrogen phosphorus potassium calcium magnesium many other things that helps the plant actually grow to its full size and finally soil
provides a medium where where water can can be held so that the plants can drink especially if there's no rain because the plants always need a supply of water so let's contrast that with what
hydroponics is it's really not so different so first of all you need some sort of a medium so there's many different types of mediums so if you look here on the left this is something called rockwool which is it's kind of like cotton candy that's made out of rock and on the right we have cocoa core so it's made out of coconut husks and both of these mediums are pretty good for holding water so if you're not if you're not watering all the time then the plants will be able to survive for a couple of hours over here these are some
different types of mediums these are in the bottom corner is gross stones which are a little bit like rocks except a little bit lighter weight and then we also have clay pebbles on the top so these mediums they provide structure for the plant but they don't actually hold very much water so you're gonna need to give these plants a constant supply of water so just looking at this in a very
very very basic hydroponic system you see this is something like clay pebbles and they're they're held in a what's called a net cup so it's like you can imagine a net it has holes in it so that the roots can eventually get out of the cup and get into the water so that they can drink and then the final aspect of
hydroponics is the the nutrients right so because you have these inert substances you have water the plants really need nutrients in order to grow so to get nutrients you just got to go to some hydroponics store and you'll see all these funky looking bottles there's sometimes they come in single varieties sometimes you have to have like multiple different solutions to feed the plants also during different stages of growth the plants need different nutrients so for for cannabis like you have the vegetative stage which is where the plant is growing to its full size growing all its leaves and then you have the flowering stage where the plant is actually growing all of its buds so you can imagine during these different stages of growth you're gonna have different nutritional needs which is why you'll need different nutrients so why
would anyone use hydroponics over soil it seems a little bit complicated but one of the main factors is that you can actually increase your yields by about 25% if you're doing it correctly
another factor is that you can grow the plants about 30% faster again this is if you're doing things properly of course so why would so why is it like this
well if you see like on the on the right side you have the the plant in soil and you see the roots are are trying to find a place to to grow into so that takes a lot of energy for the for the roots that grow into so if if it didn't have to use that energy you could use the energy to to grow up instead so if you see on the left you see this mass of roots because it's just roots that are growing in water so for them to grow they don't have to expend so much energy and so just kind of a rule of thumb is like the larger the roots you have the larger the plant so if you allow your roots to get very large you're gonna have a much larger plant another thing is that when you're
feeding plants in soil you're actually going to be feeding these microorganisms in the soil which will in turn feed the roots of the plants so with hydroponics you're using these sometimes inorganic nutrients salts which go directly to the roots of the plants so you're skipping one stage of the process which again allows things to move a little bit more quickly and then finally for us and a
lot of guys that are doing hydroponics it's really good because you have so much control over everything you can always you can change the nutrient levels on the fly you can change the pH on the fly and so when you have a lot of experience it can really help you dial in your environment and really get the most out of your plants so of course
there is still some reasons to use dirt core if you look at the photo on the Left we just have a plant sitting in dirt and that's pretty basic and you just apply the seeds and the dirt and and let it grow of course you need some light and then of course on the on the right side you have this very complicated hydroponic system so already have comp complexity just just to get it set up and in this case the system needs a pump in order to work and the water is constantly running through it so if you have the pump fails or anything like that there's a there's a good chance that your crops can die so you're definitely gonna have some complexity there and then another pretty big factor
is that soil typically gives a better flavor for the cannabis plants because there's just a full spectrum of nutrients in them in the soil of course there's there's a lot of things in there that we know what they are different types of fungal organisms lots of nutrients there's also a lot of things that we don't know it's in the soil so when we're trying to create hydroponics nutrients we're only putting certain different nutrients salts in there so there's going to be some things that are missing however you know people are figuring out how to make them as close to soil as possible and also it's not necessarily hydroponics you can for hydroponics you can use organic nutrients which are made of organic materials but that also has some challenges because they can be a little bit Messier and can cause more clogging and in the different systems alright so
next we're gonna start off kind of explaining a few commercial systems that
we've seen in facilities that we've visited and technical difficulty alright
so this is a drain to waste dripper system this is one of the most common systems that we've seen in visiting commercial facilities it's a relatively low complexity system and we're also able to grow a lot of smaller plants rather than growing kind of a smaller number of large plants and so if we look kind of at the system here it's characterized by you'll have some sort of reservoir or a source of water that will be distributed to drippers that are connected to the top of rockwool cubes or a dependent you could also use different mediums and the drippers will be put on timers and they will give off a nutrient solution over the set interval and then any excess water will run through the rock wall cube and then run down a leach tray into a drainage system or drainage reservoir here's an
example of a farm we visited in California in Los Angeles this is room one of nine they do in kind of different batches and then they have a central nutrient mixing and reservoir system in a different room and they'll be pumping those nutrients into the different rooms here you can see that they have a large number of plants on looks like five trays and these trays actually they they're rolling trays so that you can have one aisle way and then you don't have to waste many hundreds more square feet in a commercial facility and this is a very important factor because it really helps reduce the the cost of maintaining the environments and here you can also see on the top of each of these rockwool cubes there's kind of a green little kind of plastic attachment and that allows the the drippers to that distributes the water from the drippers across the rock wall cube more evenly and then from these leach trays they'll go down into a central collection system and we actually have another facility
this facility is a little bit different they're actually a vertical cannabis form and they're in Colorado and so it's really cool about these systems is they can go between six and I think twelve to thirteen levels and the lights are actually in between so that they get side lighting and the plants kind of grow towards the side again we see that we have moveable racks to save the square footage on the in the facility and also to help kind of space the lights between the plants there are drippers that go into each of these blue buckets and then at the bottom of each bucket again they're being drained to a central you know waste and actually this facility goes directly into the municipal sewer a lot of facilities water consumption for these drains waste systems may be a little bit higher especially if you don't have your timing and everything set correctly so water usage and become an issue especially if states like California may be or is implementing new regulations where you can't dump these nutrient solutions into the municipal sewers and then you have to pay for transportation and off-site treatment you are a wasting nutrients and water that you probably had to pay for so there's there's a bit of waste in this type of system especially if you're not using a control system that's properly dialed in another thing that's a potential hazard to watch out for run kind of systems like this this facility uses a centralized in-line nutrient mixing system so basically what this means as they're pumping the water through the the line they're adding the nutrients directly into that and it gets directly pumped right to the plants usually that's nice you don't have the central reservoir although if somebody makes a mistake you can see millions of dollars worth of product killed in the matter of hours due to this problem there there's not too much you can do about it though these are in a medium that usually can hold some amount of water so you have a little bit of a buffering if you have a pump system that goes down or something like that and
next we have a recirculating deep water culture system these are a slightly higher complexity a harder to use they're also significant somewhat more significantly expensive to set up but what you're really able to do with systems like these is grow a smaller number of really really big trees like really big cannabis plants that there's the farms that we visited they grow up to like maybe eight nine feet tall these tree I mean they're just beautiful it's crazy and so really how we're able to do this is each plant is sitting in a bucket and you'll have a net pot that just has like those clay pebbles or those kind of gross tones that just give a good amount of support to to the plant and then the roots just grow right into this bucket which has a lot like a large reservoir a large amount of water that's being recirculated kind of through the system so each bucket is connected in series and then there's also a control or bucket that is generally attached so that you can take measurements on the system and also centrally add nutrients and correct for the pH in the water and since this is being rapidly recirculated through the system you can have a generally uniform nutrient profile across D system and so let's move here
so this is a facility we visited in Rhode Island there a medical facility and right here at the in the center you can see the main control bucket and that's attached to 24 plants and then also right to the left of that you can see a water chiller it's important to keep the the water temperature sometimes around five ten great ten degrees cooler than the ambient air temperature and so here these trees aren't at full maturity but you can see that they're a bit larger than the the previous plants before but you you're also definitely limited when it comes to kind of setup because these buckets they have to be a very sturdy and the the plumbing is a little bit harder to set up than just these kind of little lines going to the tops of more or less normal buckets these systems also cleanliness is extremely important so that's why this facility you can see is very whitewashed and it has very clean floors and stuff like that so this it generally farms that we visited that are dirtier have a lot of problems and then farms that are kind of cleaner and they have standards they're able to keep pests and other diseases away from the plants and yeah next we have a nutrient film
technique system this is generally actually not used for cannabis we haven't seen it but it's still kind of important I think to show you that they're just kind of if there are a million different ways that you can set up a hydroponic system with these basic kind of core principles again here we have a more or less central reservoir also in here we have an airstone so for these recirculating systems they use less water but we also have to make sure that we're maintaining the kind of the nutrient pH and oxygen levels in the water so the air stones will be bubbling generally regular air or sometimes people will just use regulators and pump straight oxygen into the system this is actually to kind of feed some of the microbial life that you will see in a hydroponic system so for a nutrient film technique system you'll again have a water pump that will pump to the top of a channel and then this is at a slight incline so that or decline so that the water will sort of run in a thin film down this channel and then the smaller plants will have their roots there in kind of netcups again with clay pebbles or something like that and then the roots wool can get some of this nutrient film as it runs down and then ultimately it drains back into the central reservoir yeah so let's look at this
facility this facility is Gotham Greene's there in Brooklyn New York they're actually on top of Whole Foods and kind of the the nifty thing that they do here is they'll actually pick the produce packaged it bring it in to Whole Foods and then people will buy it and says it was picked at 1:15 today really fresh and it tastes a lot better to have locally so and we're just seeing now that hydroponics the the cost of Technology the efficiency that people are able to achieve this is becoming cost competitive with the large commercial farming especially on the the leafy greens kind of and those like spices as Basil's and stuff like that it looks like this is growing a lot of basil right here in this photo and so here you can see that we have hundreds of these gutters that are just lined up and then towards the the middle here on the right side you can see the the nutrient lines and those will run delivering water and they run down to the center here all of these channels are angled and then they'll kind of recirculate again they're these systems are kind of hard to clean again cleanliness is important so it it causes a problem to have so many kind of channels that are hard to clean and stuff like that and especially with these recirculating systems you run the risk if you have a pathogen that gets into a system you're again feeding and recirculating to all of the plants so you do run the risk of killing basically all the plants per system which is why they'll generally limit kind of the the fate like the fates that they tied together on the plants so the limited to maybe two thousand square feet of these channels will be one reservoir and then they'll kind of like multiply that as they have a different scale so other rooftop greenhouses they had like kind of they're about 10,000 square feet and they had about six different systems going all right next up we have
aeroponics which is a another system generally again used for smaller leafy greens what's really great about aeroponics is one of the most water efficient systems in general and they're able to grow plants quite quickly so in the system here you'll generally have water in the bottom and a pump that'll pump up to these small misting nozzles that will missed the the roots of the plants again we're getting a very nice mixture of air nutrients and water to the root system which is highly highly important but what you will see aeroponics is definitely used pretty commonly in cannabis just not for growing the plants
it's used for starting clones and so what clones are right they are clippings from - what are generally referred to as mother plants or sometimes they'll clip it off of other plants in production and it'll be one kind of fan leaf with a few inches of stem they'll put it into these green collars and then they'll have this aeroponic system so on the right side you can see these green nozzles those are their aeroponic misting nozzles and they're blowing they're spraying the nutrient solution and sometimes they'll also add root starting hormones to this to encourage root development on the plants and you can see pretty exciting root development very quickly on plants that you would otherwise think you know it's just like I just clip this off of a plant and all of a sudden like you're able to kind of clone it very easily which is kind of an exciting idea and this is really important for commercial facilities because consistency is extremely important so this allows them to have an entire crop of genetically identical plants they'll all grow to more or less the same height and stuff like that you know you'll often see like if you were just cracking seeds and growing fresh like you hope you'll have one plant kind of short not not very attractive like not a lot of flower on it and then you'll have other plants just there for some reason they're twice as high they have better spacing of the flowers and stuff like that so this is one of the kind of important things on the genetics and kind of continuing the generations of these plants as you grow hundreds or thousands of them and
so that's it for the the hydroponic systems that we're going over there are million different ways to actually set up a hydroponic system based on kind of the core principles of a nutrient solution being somehow distributed into the plants and making sure that we're emulating some of the conditions and the things that are provided by soil and then there are also a lot of other environmental factors that we didn't necessarily go over such as lighting which is generally interchangeable between kind of the different ways that you do it and you know we thank you all for coming here and the opportunity to come and speak to you guys and we'd love to answer any questions you you have any questions yeah so I'll go front so like aquaponics that's a method of hydroponics where you have fish as a part of the the system and you you feed the fish in this system and then ultimately it's the the excrement from the fish and you have to make sure that you have a part of this system that can with bacteria and other microbial life to process this and make the nutrients bioavailable to the plants that it we don't really see it too often in cannabis it there it's a little bit harder to maintain yeah because you have kind of have to take care of the fish and then the plants and so often on a commercial setting like the the variability that you might see in in the plants especially for cannabis is tougher you will see it definitely a lot more on kind of the leafy greens because their requirements for nutrients are a little bit less stringent sure so yeah as you're trying to optimize the environment there's like a lot of different things that you have to take into account so you're gonna be taking into account the the temperature humidity co2 levels light levels that's like all the things in the air you also need to make sure you keeping track of like the water like the the nutrient levels pH the water temperature so basically you want to be collecting a lot of information also you want to have like cameras taking pictures of things if you really want to get to that advanced level so that you can have all this data coming to you and then you can really see like what's going on so like that's kind of like the next step at in farming and like that's farming of the future is collecting tons of data and then making like small optimizations to the environment so you can see growth and like comparing things like in a scientific way so yeah I think that answer question or no yes it definitely runs the gamut newer farms the the one in Colorado that we showed you that was a pretty newly built farm they were relatively like they were relatively highly automated although a lot of the the system could really stand - for a lot of improvement right now a lot of the technology used in cannabis is more of a it's kind of ported over from traditional greenhouse agriculture which is sort of stuck in the 80s so or maybe the 90s rather but you know it we we definitely see that there there's a lot of room right now where technology can assist in growing cannabis in particular since it is such a high-value crop and there are a lot of things that we still don't know about the plant says it since it's been generally unstudied or under studied so I think as we move forward getting more data getting more insight keeping track and more things we saw the the farms that had better data recording practices I mean their most of the time they're using clipboards still even in kind of the relatively advanced farms so it there's a lot of room for improvement but the data is a driving factor yeah where's like most yeah mostly if there's a there's a lot of work that the growers are doing it's mostly not computers the growers have to do lots of things they have to cut the clones they have to move the plants around they need to feed the plants to take magic yes sure so I'll tell you a story about like one of our customers so we're very new we don't we have one customer that we that was like our early adopter and he said and he was spending about three hours a day maintaining his hydroponic system so that was measuring the nutrients measuring the pH making adjustments trying to make sure that the plants were optimized so when he incorporated our automation systems which automatically feed the plants and take care of the nutrients of pH levels he said that he now instead of spending three hours a day spends about 25 minutes every 20 days on the same activity and so for him as a researcher he's now spending more of that time doing reading research papers and figuring out better ways to optimize this plant so what we feel like we're doing for for this example and hopefully for many others is giving them an opportunity to increase the value of their operation by doing more higher value activities tor did they allow you to sample so in these farms you're not really allowed to like sample it you know because you have to actually have to go to be sold through a dispensary or something like that however we were allowed to like maybe hang out with the farmers afterwards and maybe sample some of their products so yeah I mean and I'm not even sure if all the farmers that we like sampled that was their products or was was a product that they had yeah I'm not I'm not like a huge connoisseur so it's hard for me to tell but from from what I could tell like they're the products were pretty good when we went to one of the farms in Oregon like the guy he gave us likes and some joints and they were really cool like we uh after we got out of the farm we went because in Oregon was just placed at Hood River Oregon so it's like gorgeous scenery and everything so we went to this like River really close by and like to smoke some one of the joints and then we started thinking of always like really crazy ideas a flower gonna like help him so so it's like he helped us like help him yeah we wrote him down he I gotta write them down yeah so for the most part we saw kind of the the traditional halides and stuff like that they're less expensive and the capital expenditure for setting up farms is relatively high we a number of the farmers that we visited including the one in Oregon they're typically experimenting without LEDs they're looking into it one farm they had one room that was using LEDs and another two rooms that were using the HIDs and stuff like that LEDs are coming it's definitely going to be one a very important factor states such as Massachusetts actually have laws limiting how much electricity you can use per square foot essentially making it that LEDs are really the only real option so yeah LEDs they're they're great there there's some things we don't fully know yet about maybe the the light spectrums although there are a plethora of companies that are working on it and selling the best lights in the industry so you know we're we're excited to see it move more towards the LEDs maybe once a little bit and less expensive to install which I can imagine but is there like a standard like after I barely grow futures like a food system yeah I mean I'm sure like each goer kind of has their own way of doing it but a lot of times you're when you're taking the plants like out of the system so like sometimes it could be like two weeks four weeks when you remove the plants like that's usually when they'll go ahead and clean them they're not usually going to be clean them like while the plants are actually in the system and it's definitely cleaning should probably be more of a constant practice rather than something that people are doing here like at specific intervals like some of the farms we visited they they don't have like a speck of dust like speck of water anything on the on the ground and you know they're able to use you know it sends like no pesticides and you know by just using extremely rigorous cleanliness policies we some of the facilities we go into we're literally put in like kind of like jumpsuits and crocks and we're spraying alcohol on the bottom of our feet and we have these little pads as we go into each room and they don't need to use any pesticides other facilities we visited there basically they are open to the public they let people in there are rooms that have they say don't go in here we just like sprayed pesticides in here like you know it's gonna be a nightmare so it really it really runs the gamut you know of different cleanliness practices although definitely the the farms that are doing the best for the most part are doing it with rigorous cleanliness standards and and that's one of the things that automation would be really good like automate certain tasks like nutrient dosing so that people can spend more time on cleaning to ensure that you know they don't have an entire room you know get you know spider mites or something and then it cost some millions of dollars and then just like add to that another reason for automation is so that you don't have to be constantly going in and out of the room and changing things all the time like humans are one of the greatest sources of contamination of the of the system so by having less traffic touching the plants less you're gonna have less chances of having these problems yep I actually really curious what yours looks like but uh I yeah we haven't I don't know I can't think of anyone to top my head the one farm in California that we visited they had one room that was like a deep water culture room and then they had eight rooms that were the the dripper systems and but they actually just recently shut down the deep water culture room commercially speaking they'd like it to be uniform just have a standard operating procedure and have it kind of more like a manufacturing process and then you'll see hobbyists and people who are doing on smaller scales they might be playing around more or even farmers who are maybe like not quite getting started but are planning to get started they might be kind of experimenting seeing what system they can handle the the best did we see any yeah yeah it's definitely kind of consolidating the markets in general we also visited an outdoor grower in Washington and he grows 35,000 pounds a year which is essentially unheard of for indoor growers they're like if they hit 5,000 pounds that would be insane I usually you know maybe they're around one or two thousand and I mean this like outdoor is he's the low-cost producer in the state he can blow it out he can sell he sells eighths for 25 to dispensary you can have it out the door for 75 the in that there is definitely though kind of a space for the indoor kind of growing with hydroponics because you're able to play more with the chemical profiles and the plants you're able to get kind of this higher quality so you'll you'll probably see the lower end of the market get pretty much completely consolidated especially once you have a federal legalization there's no way you're going to be able to really compete with you know John Deere tractors in massive fields but you know we will probably see you know and this is kind of this is really more opinion or sort of like kind of in the ether but you'll probably see something kind of like the model of like the craft brewery like kind of with beer like you have like your craft breweries you know kind of focused on quality and like you know no pesticides no this not and then you know the outdoor you'll have your Budweiser's as well the outdoor drawer I'm not entirely sure they have they they have a permitting system based on square footage so they have permits of 30,000 square feet that they multiplied well they had room for a hundred paragraph they maybe had like eight to ten permits that they were growing thirty-five thousand pounds under and these like the the regulations in Washington made it extremely inefficient for them actually to do the farming because they had each 30,000 square foot plots separately staked out and so they could own they had fencing around each one of those so it you can really the economies of scale as the the regulations may change could really change the landscape of the de Laurent yes yeah I mean typically you want to use something called like a carbon filter which is just like a fan that's gonna be sucking up all the air and making sure that it takes out all the different things that smell from the cannabis plants so in if you want to have like a commercial facility somewhere then you definitely need to have that because you don't want to be blowing out on all that seven and if you're growing like in your house if you have like you know some sort of a grow tent you can set up like a small carbon filter so you can take care of that pretty often states have regulations and say like once you're outside of the facility like you know you should not you know be able to small it that's not necessarily true for probably most of the facilities we visited like when you're outside you know what where you're going so yeah yes [Music] yeah so security is you know definitely a major part of these facilities mostly on the regulation side the regulations are often very stringent and explicit on what sort of security is necessary I think most of the time what we've seen is that there's a camera everywhere there's like you except the bathroom but basically anywhere you go in many of these facilities there's a camera on you and the state has a direct link into each and every one of those cameras so there could be someone watching you in the you know tending to plants trimming drying rooms everything cameras everywhere everywhere everywhere and California is implementing you know new regulations that have much stricter security concerns and even the outdoor there was a camera on every corner at least of these plots again someone's watching over your shoulder every step government really wants their tax money see grow operations with Auto elevating tables and beg his ship to move water around to keep the level or keep everything clean there's a lot and then you look to the left and there's a massive sets of PLC's that are connected to a bunch of other bullshit somewhere else that work is one of the things that I'm curious about how are they thinking about those systems yeah so the the the state doesn't really you know the states don't care if you got business generally so they're they're really watching the people in the facilities that's what they want to make sure that every little gram I mean every leaf died typically needs to be pretty much accounted for and disposed of with you know different procedures and you know again depending on the state you might be weighing the plant right when you cut it down weighing the flower that you cut off weighing the the trim that you took off and stuff like that in terms of the technology the PLC's the control systems we haven't heard or seen of any integrations with the the state really besides maybe like seed to sale like tracking so they might be in kind of the inventory management systems but environmental control systems they don't care if your plants die they just care if you know someone is kind of diverting something to a gray or black market some farms are more technically sophisticated than others although we haven't seen you know too much technical sophistication in most of the facilities any other questions thank you very much right thank you so much
