couple of questions about my buddys aeroponics setup:
1.) should the pump run 24/7 or in spurts like an ebb and flow?
2.) it has 3 inch net cups with growrox and it seems to get the rockwool soaking wet, is this a bad thing?
3.) theres one sick plant that stopped growing, so he took it out and looked at it and the tap root had grown back up through the rock wool instead of down, can he fix this or should he throw it away?
thanks!!
