I love my plastic air pots.
-elevates pot off of surface it's on preventing the plant from taking up runoff water
-they stack together for storage very nicely
- follow the directions. The top side usually has the first few without holes and they want the bottom peice pointed a certain direction . Just follow instructions.
-when filling with your media I recommend doing it semi moist and packing the media out into the pot while filling up. If you just dump the soil in alot of the cones won't be filled up. I use coco so I can press very hard when packing but soils may be different
-if drying out too fast be aware of fans hitting the sides of the pots thus drying them out. you can shield them with something. I have my fans above the pots but sometimes I use floraflex matrix capillary pads with the matrix rings which really help the water disperse correctly. I use the pads in the winter when it's dry and don't use them in the summer cause it's humid here.
Good luck!
