I made a iws system. Sounds like what your talking about. Flood and drain but res is same hight as plants or lower.
Use a pump in res to flood, need vaccume brake for anti siphon if above. I ran a res just full enough to not over flow plants and control bucket, so no worry about a high level...
Ill se what i can do. These are in small pots so not the best of conditions. I think they are 1.5L. Crowding dosent really make for good lower buds. No toping either just let tem go. They are streatchy. Ill se if i can get a pick when i chop.
K this gloomy wet weather can leave. Have a bit of bud rot in some plants. Running 2 dehu. In the GH at night. Chopped a couple plants.

Macaww. She had 2 mains I took the tops the other day before the fungus did. She had some fat stinky purple colas.
