Thanks, that was good information. I'm getting ready to set up a dwc system in Fiji to try and use the thermal mass to mitigate the excess heat we have here.
Plan for excess airation in your setup, use high strength hydrogen peroxide or hydroguard to protect the roots. A Milwaukee dissolved oxygen sensor would be a great investment eventually, if you are experiencing slow growth or root rot👍
Can you go over the cost of this. Maybe a quick comparison between this and your NFT for roughly the same size system? That would be awesome. Great videos, they have been super helpful setting up my systems.
@@SaludaGradeFarm Oh could you also do a spot explaining the floats? Like size of trays, media (I assume oasis), what your production process is, in terms of a nursery DWC or something like that? Thanks again.
@@SaludaGradeFarm thanks for the response. Truly appreciate the time and effort you put into your videos. I want to grow onions, so any help you can provide is a big plus.
How often does a system like this need a water change? If you don't ever change the water, it would be really interesting to know how you avoid nutrient buildup / imbalance.
I pump this nutrient solution out to my other systems that go through a lot, and then I top off about 50% or the solution, everything grows at an an alarming rate, so must be working.
would be interesting to see the temperature in the water troughout the whole year also with the airtemp. and for us europeans it would be nice to have it in Celsius C. Thanx. (ps. i would heat the water, not the air)
I’ll do an update in the summer, hopefully it stays cool since it’s on the ground, but we also have moderate temps here, day time air temps are 28c on average. I’m hoping I won’t need a chiller.
Hey dude, thanks for your showcase and tips, it'll be useful when I make my own install. Let me share with you a tip to get a bit more money. It looks like you are using rockwool cubes for seedlings? Those are not very cheap. There's a couple of videos on "Shorts" category from "Israel Hydroponics" channel, looks like they put seeds into custom trays filled up with just traditional (and way cheaper) compost, the custom trays make the roots of seedlings taking a shape robust enough to extract then trasplanting them to those rafts pretty quickly, go check them it's the first result on search page.
@@SaludaGradeFarm nice thing about those custom trays is that the single tray host more density on same square space, and even way more since they can be stacked vertically if each plane get a half inch of fertilized water to keep those trays subirrigated, that would free even more of your greenhouse space
Thanks! I should’ve gone thicker but by gods grace it’s held so far. I might break this system into smaller ones like I’ve done on my newer ones and use a 16 mil liner. farmplasticsupply.com/hydroponics/hydroponic-black-plastic-6mil This is a video of my newer systems, smaller but easier to manage. I’m using a 16 mil liner for these. th-cam.com/video/vA0L0j7CZSg/w-d-xo.html
I want to do an update soon, sorry for the long wait. I am so happy with it I made another one next to it. I am harvesting 250lbs a week or 900 heads! It doesn’t get more productive than that. Look at one of my tomato greenhouse updates, I have a better system for larger plants than this.
This reservoir is 6 mil, which is not ideal, but all I couldn’t afford at the time. I have a few smaller systems that I use 16 mil in and I much prefer that.
also, do you messure CO2 in the air, with the airfans on, and then with the airfans off during daytime? would be interesting to se if the letuce get enough CO2 without venting???
Good question, the idea is the ground will stay cool, and keep the water cool too! We will see if you think about it most swimming pools stay around 70, and they don’t have a white reflective foam layer floating on them, subscribe and I will post about it in June-july!
Ingenious creativity & design! You should be very proud of your accomplishments. Totally killin’ it! Keep having fun!
This made me smile, thanks for the kind words!

Thaks for sharing, good luck and I hoop you succeed.
Thanks! We are doing great, going into our 5th year and now I have two of these system!

Will do, it will take some time but that will be later on in this series, I’m glad it’s been helpful!
@@SaludaGradeFarm Oh could you also do a spot explaining the floats? Like size of trays, media (I assume oasis), what your production process is, in terms of a nursery DWC or something like that? Thanks again.
How deep is the water in the pool?
Where did you get the rafts from? Love the series.
Thanks!
They came from beaver plastics in AB Canada. They’re cheaper from them, but freight may be more expensive.
Thank you very much.
You’re welcome, I will be doing an extensive update on this system this week, so please stay tuned in!
Great job with the system.
Could you list the components, costs and where to purchase them. Thank you.
I’ve been dreading doing a video on that, but would like to. it’s less than a good BCS tiller with attachments!

Love the setup, what kind of plastic is that and what’s the thickness of it?
Thanks!

Thanks man !
Update on this system ?
Are you happy with it ?
Could zucchinis cucumbers and broccoli be grown in this style system ?

i noticed that the one bed was on the ground, is the big one on the ground also?
All the beds are on the ground, it makes construction cheaper and easier, but harvesting harder.
@@SaludaGradeFarm thanks for the reply
Hi where do you get those floating rafts?
I get them from beaver plastics in Canada, but you can get them from hort america too.
How thick is the plastic, 6mil?
This reservoir is 6 mil, which is not ideal, but all I couldn’t afford at the time. I have a few smaller systems that I use 16 mil in and I much prefer that.
also, do you messure CO2 in the air, with the airfans on, and then with the airfans off during daytime? would be interesting to se if the letuce get enough CO2 without venting???
I’m not at the point of using co2 yet, will be working on that this fall.
@@SaludaGradeFarm i dont mean adding CO2, but getting in natural CO2 with new air.if no wenting i would think that the plants run out of CO2..?
How to you mix the nutrients? And refill?
When it’s low I top it off, and soon I will be doing water samples, and make adjustments as necessary.
How deep is the nutrient
About a 8” but I’ve ran systems as shallow as 3.5”. It doesn’t really make much of a difference.
will ya need a chiller in summer
