I started a late season grow in august, my three plants are royal dwarf, and royal jack, and are fed GO nutrients. my problem is that my plants are outside in a shed and its getting to freezing temps at night,and decreased sunlight, i've been using a space heater with a fan that has kept the soil temp around 18celsius and air temp around 22celsius. they get sunlight through a 2X3 roof panel that i made out of clear plastic. i'm at day 65 and think i have another 20-30 days to go, the leaves have not started to yellow at all. Do i try and tuff it out or make a small grow area in my closet with 10 23watt cfl. What would give better yields ? cfl are the most cost effective by far in my area and the only choice of lighting i have
