Question: I grow my violets 15″ below 4-tube fixtures. The lights are on 12-16 hours a day. On some plants the center leaves look crowded and a little hard, but I’m not sure if this is due to too much light or not.
Answer: This may, indeed, be the result of too much light, particularly for most standard-size varieties. This is particularly true for many varieties with wavy, ruffled, or girl-type leaves that, by their nature, tend to crowd in the center.
