Under Current DWC

I've been thinking about building something similar to this for over a year now. Looks like someone beat me to it.

YouTube - Under Current Deep Water Culture Hydroponic System: animated walkthrough

Definitely a cool system! The 2 biggest things IMO that benefit any recirculating system are, keeping the nute solution moving, and lots and lots of air

My system had a bit of a twist, maybe when I do build it I'll make my own youtube video.

Welcome to the garden Bruno129... Add a third thing to your list, reservoir temperature... 65 to 70 is ideal. I have found out that res temp is VERY important. Good luck and browse around here before you build. You will be glad you did...

Yes... I've always had fairly good luck with Reservoir temps in the past, I can usually keep it in the high 60's (in a 75°F room) just by using reflective material on the reservoir and keeping it on the floor rather than higher up in the room. Did you know there can be up to a 10°F diference in room temp between the floor and ceiling of a room?

CM: Thanks for the private message, but I don't have enough posts to respond.

Anyone know how the connections at the buckets are made? I did see some 2"ID SLIP/SLIP Bulkheads ...somewhere... that were specifically made for installation on curved surfaces, or is there an easier way?

Here's a link to Under Currents parts list:

Parts & Accessories : Current Culture Hydroponics, superior hydroponic systems.

You can see the uniseals they use there.

I really appreciate the link to the parts list, I think I can use quite a bit of that. Here's a couple rough pics of what I have in mind

Basically I'm using the undercurrent design and incorporating aero. That's a 1/2" PVC manifold up top that will connect to a ring of 1/2" tubing just under the lid of each bucket. The micro-sprayers will be in the tubing. The aero-spray will run down in to the buckets and get recirculated. The water level will be kept much lower.
