SPLIFFBUILDER Reviewed by SPLIFFBUILDER on . How much light Ive been reading my "bible" about lighting and cannot believe how much watage they recommend. I have a room approx. 7X9 with seven foot ceiling. I have four nice size plants growing under two 400 watt HPS lights. The book I have says that is not even half of what I should have. I'm afraid my little buddies will fry!! I already had the problem of leaf turning. Was told that means I'm too close. Help!! Rating: 5
