dang, lost a whole reply due to misclicking lol.... uh, what kind of lights are you using? incandescents as jellyman said? that one definitely looks like an incan. the generally accepted rule of thumb for cfl is 100w for 1 plant, +50w for every plant after....so 200w of cfl light for 3 plants. that's for cfl though. if you are using incans........here's the comparison: Amazon.com: CowboyStudio 150 Watt Daylight Balanced Compact Fluorescent Light Bulb: Camera & Photo that's a 150w cfl. that's equal to 500w of incans. that's still 50w of cfl less than you need. so.......you need ~600+ (+ your 135w) more watts of incans for those three plants...... may as well get a 400w or 600w hps and grow monster plants.
