How much artificial light should coleus get?
I've just brought my container coleus plants inside for the winter. I took multiple cuttings and put them into fresh MIracleGro and put them under fluorescent plant lights in my basement. My question is: How many hours of daily light do they need, and how close to the plants should the lights be? And should I try to keep the moisture and temperature within a specific range for ideal growth? The basement is moderately comfortable and temps stay in the mid 60s all winter. The light stand has a clear plastic cover to help maintain moisture to some extent, but should I keep water in the bottom of the trays to keep the humidity even higher? Any one with any experience in overwintering coleus would be very much appreciated. I have a timer attached to the lights already, so I just need to know what an ideal schedule would be. TIA.
