Yes I grow inside. I have ceiling fan and small fan blowing directly on the plants. A/C is set at 85 during the day. Have thermometer that reads anywhere from 80 to 90 degress during the day and 70-76 at night. I have been using just 400Watt HPS light. I water every 3 hours for 15 minutes. Use Fox Farm Nutes. Am growing from 4 different kinds of seeds. One kind is from a friend (1 plant), another is from what I'm been smoking (5 plants)and the other 2 kinds are Legends "Johnny Blaze"(3 plants) and Paradise "Sugar Babe"(1 plant).
