I'm doing a top feed to waste grow with rockwool cubes. I don't have tons of room to grow monsters 2x5x6. I'm going to fill it up with 3 plants, wall to wall. The question is I have 2 sizes of Air Pots 7.5L and 20L pot. Refer to the picture if you would. Also, please look at how the the drip ring is situated.
What do we think? 7.5 or 20?
Thanks
Athos
