We have three 4-column windowfarms in a college dorm. The plants that came with the starter kit have been doing more or less ok (with some hick-ups), however, I have some issues and I was wondering if anyone had the same ones and what did you do.
1. Watercress is partially dry – is this just lack of water? Should I make the watering intervals more frequent? (Right now every 15 min)
2. There is some mold on chives…. How to deal with it?
3. What could be the white powder that I find on almost each pot? Is that related to water’s high pH (9) or is that just form the nutrients?
Sorry for silly questions! Thanks and looking forward to hearing back!
