Keeping the environment moist or damp Answered
I'm building an aeroponics system from scratch. When I water my roots in bursts of 3 to 5 minutes how can I be sure that the environment stays moist while I am away, I don't want the roots on my capsicum annuum to dry out. Is there anything I can line my 4" PVC tube with to keep it damp inside but without using soil or any geological material or perhaps and organic material that wont damage the cycle? Is this what aggregate is used for?
