Hi iam using Airpots for around 18 months now.Its alitle tricky in the begnning until you are used to handle them. in the beginning just small amounts around the plant...Dont need to saturate the whole soil... if the plant is really big and needs big amounts of water.. you have to be patientwith the watering. If you have to give your plant 1l then do it in small steps. And dont let dry out the airpots to much , then its vry difficult to water them. I do it like this ( big plant) i water daily... and one time in the week i take the airpot, put it into my bathtub and give her slowly big amounts of lukewarm water , until all soil is saturated. Then let them stand for 1-2 hours and take them back to growroom. Use apot under the airpot too, so you are fine and dont mess to much water. Its akinda training but after the grow you are used to. Airpots are just great. They are doing the" aircut" on the roots... roots want to grow out of the holes, then they notice ... oh here is no way,,, they turn around and webbing in the pot.. so in the end your airpot is full of a nice rootsystem very webbed.. you know more roots more fruits......hope i answered if more questions to come just ask
