I have a couple nepenthes that i have in my dinning room set back about 12 feet from a big glass slidding door. During the summer, the plants would get about 4-5 hours of direct sun, and the rest of the day indirect sun. Well as we have moved in to fall they now get zero direct sun and all indirect. So I was wanting to get lights to suppliment the direct sun. so my question is should i use T8 or T12 or something else, how long should they be on, how far should they be from the plants? I did a search on the forum, but didnt see anything that matched my question. Any help would be most appreciated. thanks for your time
