So here I am again. Using DWC, I had issues with the last couple grows. Water temp issues. Coming into spring, too cold, all summer, too hot. Now I am making the jump to RDWC. I’ve been looking at if for a while. The undercurrent system is what I’m modeling mine after. It just looks simple and scalable.
So I looked all over and found my parts. Some 1 1/2" pvc, the big one, bulk heads, from menards. Every where they were about $14 each, menards, $7. They didn’t carry enough in store so I had to order some.
Now, the parts list.
1 10’ 1 1/2 pvc tube
6 90 degree elbows
2 T’s (1 1/2 x 1 1/2 x 1 1/2)
1 1 1/2 to 3/4 adapter for the water inlet hose
13 bulkheads
7 15 gallon tubs
10 feet of 3/4" black hose
700 GPH water pump
1750 GPH air pump (already had this)
That’s it. I’m just waiting on the rest of the bulkheads. I do not suggest cutting the plastic with a utility knife. It works, but you can Crack the plastic. I hope the superglue works lol. I had just a couple small cracks. With these bulkheads, if you put the nut inside the tub, you can glue everything together and still add or remove buckets. I might put in a valve to divert the water to drain everything later. That would be another 10 foot hose, 2 3/4" shut-off valves. With the air pump this probably cost me $400. An undercurrent system is $1200!! I think the only difference is they use 5 gallon buckets, and I’m using 15 gallon. They barely fit, but they are lower also. More headroom.

Let me know if you have any questions, suggestions, or anything
