Iv used 3,6 and 10 and they all work great. One thing I would be carful with, is they may dry out very quick in a green house, depending on you climate of course.
i have just started using airpots on my current grows, so far i have nothing bad to say about them.. the autos in the 20l ones are loving them, as are my photo plants in 20's and 10's... only had the water come out the side a couple of times at the start... i find water slow at first all round the edges and then into the center till the coco is saturated and then i can just pour away like normal..

ill definately get a few pics on the go obviously from start to finish along with my newbie questions !!! hopefully ill be able to bring my share of useful information to the whole forum thats helepd me enormously already with its tremendous users thanks to all keep well
