Hey shov...I have Skunk 47 growing for about 3wks now. I just started the 12/12 light cycle but I've never done this before. Is it too late to do this or do you think I'm good? 90 watt LED in Miracle Grow with temps ranging from 40's to 60's or 70's depending on how cold it is outside as the space heater can only do so much when it's zero outside.
