Beautiful work!No airstones in RDWC. I'm at the finish line with some of the healthiest looking flowers I've grown. Running CMH 315s, reeflo 6000 gph pump with waterfalls and not one single airstones.
I run a chiller and keep the temps at 66-68No chiller?
do you use a separate pump to run through the chillerI run a chiller and keep the temps at 66-68
Sorry I'm in no way trying to be misleading, I've been very forthcoming and transparent on my engineering. I'm using a 6000 GPH pump due to the amount of totes I'm running, it's very scalable and the only difference of a waterfall would be the removable of the 1/2 pvc with the holes drilled for the water streams. I actually restrict the flow of the pump to about 60-70 percent of its max flow rate via a ball valve. The pump is over kill for my system but I've learned through trial and error it's better to have to much than to little. I'm just showing proof that it is possible to grow healthy plants in RDWC without airstones. I am currently designing a RDWC system for a commercial grow and I will not be using airstones, just the jet system I shared in my post.In all fairness they are more than waterfalls.you have a huge pump and pipes with small holes creating multiple jets.you don't have just the return line in the control bucket.it would be unfair if people see this and pull there stones and see there plants start dropping like flies.
My question is how do you chill the system when the recommended gph pump is 550 on smaller chillers
As for the question of the chiller: I am using a 1/2 hp chiller using a 1000 GPH pump that is directly in my epicenter. I am having no problem keeping my water temps at 66-68 with an ambient room temp of 79-80, even when vegging 18/6. I do use active air through 6 inch duct blowing directly on the back of my chiller. I could make it more efficient by installing the pump inline but it's working fine submersed in my epicenter.In all fairness they are more than waterfalls.you have a huge pump and pipes with small holes creating multiple jets.you don't have just the return line in the control bucket.it would be unfair if people see this and pull there stones and see there plants start dropping like flies.

Im with you.all about it.If i can figure out a way to do this in a smaller scale 6 bucket system im on it.Im over the air stones as much as anyone else.As for the question of the chiller: I am using a 1/2 hp chiller using a 1000 GPH pump that is directly in my epicenter.

RDWCwow roots.... what system ur running?
Thank you to all that have contributed to this thread. i am currently setting up a 12 site x 45 l w/ a 102 l rez . i have 2" return lines and the pods will be fed by a 2700gph pump split down to 1/2" lines for the waterfall. no air stones . Im glad to see your guys systems working so well for you . I have been growing in dirt for about 6 years but im tired of the mess that comes with the dirt. I ve been researching UC systems for several months , on many different sites & THCFARMER is definitely the authority on UC systems and im glad to be a part of this community. looking forward to sharing my experiences with you guys.
New system I just built without airstones. Each tote has an adjustable ball valve with a jet type system, running off a 2800 gph reeflo pump.
