Ya I've done all that. But if I had to do it over again I would of bought those square buckets like you got. I looked into em but the shipping turned me off.
So I just went to Walmart and bought 20 gal totes.
Started using 3" uniseals and ended up busting half the totes cause of how hard it was to get the 3" schedule 40 pipe into the seals. And half of em would drip cause the concrete floor is uneven. So I had to cauk the shit out of em to make sure no leaks. For the tops I just cut out a hole for the 8" net cup to go into.
I got about 2/3 done and decided fuck this!! And bought 3" slip slip bulkhead fittings. When you step up from 2" -3" fittings their is gonna be price jump!
I do not have to worry about roots stopping up my lines though lol.
I also top feed instead of using airstones. In my veg tent I have 18-5gal buckets with 1.5 line and uniseals and waterfall technique.. Tried using bulkhead fittings but that was a worthless endever is the bucket was to curved to even try . I could tell by looking at it when I stuck em in the bucket it wasn't gonna work. Also used silicon around the seals and pipe/ bucket to make sure no leaks.
Heres a couple picks of me mocking it up and getting it together.
I'm going to take it a part and just use it around the outside edges of my room.
The other pic of the buckets is one of my veg tents.
Root pic.is my typical size root if flowering a 18" plant. I flowered a jack herer that was 2' tall and it swallowed the other plant next to it. It's base was as big as your forearm and yielded close to 2 lbs in one tote.
