Hey, sorry it’s taken me a while to get to making a video on this one, here is a link to an older one, that’s a bit smaller but can aerate 3-400 gallons easily! ruclips.net/video/BaxPcKiuBwM/видео.html
Without a massive air pump you will probably always have the problem of root rot. As a preventative you should be using Bacillus amyloliquefaciens strain D474 or something similar. Your plants should get a root drench before transfer to big bunk. This particular bacteria is safe for humans, it works by bonding to plant roots before fungi (Pythium) get the chance to. Could build a smaller bunk for root drench before sending off to the big one. Hope this will be helpful to you.
Thanks for your input, I do use BA, but to control biofilms. I have only had issues with root rot during periods of really cold weather when pythium is growing, other than that, I have never had root rot in my Floating raft system with my venturis running. Now my NFT is a different story, root rot is very common in that system, drives me nuts 😆
Hi, I love your videos very helpful, thanks for sharing!!! I have one question for you, how long you turn on the venturi system to get a goof aeration water and that good shape of roots plants?
Thanks for the kind words! I run it 24/7 because that’s what’s required. This system is pretty large, about 5,000 gallons, and the pump only requires 4-5 amps, so it’s not that big of a power requirement. If your concerned about electricity usage you can check out the kratky method.
I’ve gotten away with as little as the height of a 2x4 in a small 4x8 system I put on a table. But optimal is 12” if you want a good stable system where the ph ec and temp doesn’t bounce around. That’s the beauty of this, there’s really very little daily maintenance. You can actually go on vacation!
I'm running "DWC" in mixing tubs and also standard flood trays- 4-6" is enough. My venturi video: ruclips.net/video/JDiEwkcwORs/видео.html I'm about to make another version.
Hi. I have a question about nutrient replacement. Do you have a reservoir or is the table the reservoir? Also, how often do you change the nutrients? Do you replace the entire 5000galons? Cheers
This system is on the ground, so there’s no table, but there is no external res. I don’t replace the nutrient solution, but top it off when it’s low with fresh solution. I will probably start pumping the solution into auxiliary grow bags, or into my tomato/nft greenhouses!

Fantastic
Thanks!
Good job!! More efficient and cheaper than air stones.
When will we see the instructions for building the venturi? We are building our floating system

Cant wait to see the venturi video.
For dwc, what's the minimum & optimum depth of water?
I’ve gotten away with as little as the height of a 2x4 in a small 4x8 system I put on a table. But optimal is 12” if you want a good stable system where the ph ec and temp doesn’t bounce around.

Hi! Does those pumps need to be on 24 /7?
Yes, I have quite a few pumps running 24/7. It doesn’t take much electricity to operate them.
Cheers!
Hi , Mum and Dad 😂
😂😂😂 he gets tens of views 😂
Bro Do you have FB page, IG or Twitter account?
m.facebook.com/100064846660975/ for you I’ve got anything 😂 love your videos
@@SaludaGradeFarm I was able to achieved this amount of bubbles. Unfortunately it did not work on my reservoir which is 1.5 meters deep. 🤔
