ok I got an update on this thread now, I have been testing 4 one litre airpots for the last 2 weeks, I could not do any side by side tests cos I only use seeds and do not bother with clones these days so results would not prove anything, so the only comparason I can do is from memory of past grows with normal pots (coco). Ok so I used the following strains from fem seed the plants are now 3 wks old, Super skunk, LSD, Vanila kush and Skunk#1.
So far these pots are doing just what the ad says on youtube, if you undo the pots you can see the roots that have been pruned, they are branching out well and look white and healthy

the growth of the plants looks good too they seem to be thriving well.
I am very impressed with these airpots and I wont go back to normal pots.
Not everything I type is the whole truth......
