Greetings everyone! New to the forums and longtime carnivore plant lover. I have four 4ft sunblaster T5's high output with reflectors about 11 inches from the ground and 7 inches touching the top of the pots. I am growing about 8 different mexican butterworts, drosera regia, 3 different cephalotus colonies, U. Longifolia, nepenthes ventricosa. These T5's with high output give off some heat. My question is what is considered the correct distance from fixture to plant. I don't want to loose lumens if I have to raise it too high. But I don't want to cook my plants either!
