I wouldn't mess with the lighting too much, and give them plenty of time between changes if you do. Throwing little monkey wrenches like changing lighting intensity and source into their lives is what throws up their red flags and causes sex changes. My understanding is its a defensive technique if there's a harsh weather change like an early winter to ensure the existing females will be pollinated.I had 2 plants outside and 2 inside my cab. It go way to hot outside (100 plus). I moved all 4 plants under 24 hour veg. lighting. Will this hurt the 2 outdoor plants?
