 Where was it? We had the hack where when I spoke about the Yeah, it was in years over in US. I spoke about because back then I was about to move into my own place And we're working I was working on a shelf garden, which I wanted to keep at home, but Things progressed from there and ten years about a year a year later Came here to do another talk on our progress and every time we build a new prototype It just started getting bigger and bigger and bigger and last year. We did a tech Saturday together with SL And our first week we had 32 volunteers We just came and it was crawling with people and we were all busy building and construction and Over time obviously the enthusiasm doing a little bit But over the course of the next 10 to 12 weeks We managed to finish the entire rooftop space for our first phase of what we said was going to be our experiment for this year So that's what we've been doing for the past year We've been experimenting and getting it's going to show you Once you can connect what we're planning for this year because instead of fine-tuning what we have we've decided We're going to take what the lessons are we've learned from that one and we're going to Build a next model even bigger than before Oh So usually with hydroponics and usually with this type of rooftop farming what you do is you do a mono Crop you do only one thing and to optimize for that one thing But what we did is we decided in the line we're going to use a dustpocket version which is very versatile And What we did is we decided we're going to grow a variety of crops just to test and see what works In the environment if you want to grow so we've grown everything from kale to Bok choy to tomatoes and chilies I we even grew one jalapeno So that worked we grew corn and we are busy experimenting with marrows and pumpkins So and obviously there's a white variety of roots as well mint bezel Firstly these types of things grows well in this environment Depending on how you treat them so what we have at the moment is We started off with the tech Saturday We started off a huge dustpocket system with 80 buckets. We filled them up all instantaneously, which was a mistake It was too much for us to handle all at the same time. So We should have phased them out slowly But because we wanted to experiment with a lot of things we just said just for everything in tomatoes grows Incredibly well. We're very happy with that one. So that's one thing we'll be focusing on once we go professional And then last few months what we've done is we built an extension, which is at the bottom here the NFT system Which is much smaller space But it can handle a lot more Quantity in terms of positive show if you grow a leafy green like bok choy The test we wanted to do here was to see if we could okay We've already done this and see what we can grow. So now we wanted to test and see if what we can grow We can we do it consistently and at Good consistent quality at a larger scale. So we went and we sowed 220 pots of bok choy and they all turned out beautifully very fresh very nice very tasty and It worked out wonderful. So now we're back to testing the large variety Because we already know that's that test we passed and then that's what we're going to implement in our next system Which is our current system as you can see this is the rooftop space currently you've got one small storage Box there in the corner. We've got a red the red spot is the thousand meter tank Then you've got any buckets in the line and 11 Trunking it's it's a system. We have together literally we have to get it from air-con Trunking and electrical grommets and PVC piping that we made the whole system And then everything just filters back. So this is what the farms going to look like Within the next four to five months max hopefully It changes from 80 buckets to almost 2000 buckets And it changes from 220 slots to almost 2700 slots for leafy greens Which would be quite substantial? for Supplying to say for example the local school canteen as an honor So we are hoping to grow a lot of things especially we're going to focus on things that we've tested with huge success as far Ladies fingers turns out very very good I would love to be able to show you but we don't have any ladies fingers at the moment To show you a comparison between what I can buy in the store what I can grow. It's really The only thing I can say is freshness matters If you buy stuff from Malaysia and you transport it over to Singapore. It's really not the same thing Once we grow to a substantial scale We'd like to invite everybody over again for another party will do a launch of course and we'll let you go and taste our produce Ladies fingers tomatoes long beans basil kale butchers all these things we've grown here with massive success and they taste amazing I Haven't bought any of this stuff from I This is a sample of the size of So literally you can just like bite like this Right Oh Well, okay, yeah, we got some I want some too I So later on Just to show you it's very basic how the system works. We've got a main tank It circulates the water through the parts from through it in FT system Then it circulates the water back through a central flooding chamber Which passes the water all the way back to a sumptown where we've got a level switch that pushes it back into the main Anyway, it doesn't matter. We're going to show you guys how the system works in person later Yeah, so yeah, thank you Hang here after the all talks are done and Checking it out will be really cool because I've been taking pictures. I've never seen in real life. I'm super excited
