First off, I'm an inexperienced grower and this is my first attepmt at Aeroponics. I bought my system from an experienced grower from California. It is a bottom srayer (root system spray not from the top). According to him, the sprayers should come on for 1 minute every 5 minutes 24/7. He says to never let the roots dry or approach dehydration. At most never longer than 20 minutes off. I am currently running my system (32 days from seed) at one minute on and ten minutes off. Everything was beautiful until 2 days when I noticed some stem issues. The plants are beautiful and full but I am trying to troubleshoot the stem issue. My man from Cal says he has never had this problem and does not believe it's from the spray time.

Again, I'm just a novice (try to learn and perfect this type of growing) trying to pass on some info from an experienced Aero grower.
