Now you got me worried, I really want to grow more plants in the same space keep them smaller and have kind of a large selection of exotic strains. But I might have bought the wrong size air pot. I've been thinking about ordering more and thinking maybe I should get bigger ones but now I'm thinking I got to go smaller. Problem is with Coco I could end up hand watering two or three times a day or I guess I have to go auto water I don't know
I was thinking that with the large 20ltr, the PE roots have taken a lot longer to reach the sides and bottom. but in the small pots the root have reach them much quicker, at least 5 days faster. You can see it the pics with suddenly the PE taking off at day 20.
I'm think of getting the 15ltr (3-4 gallon) now, I under stand why they are favored by most air pot user's.
