that light is good.. I don't know about the quality of that bulb though.. I'd suggest going here http://www.insidesun.com/index.php?a...=2&prevstart=0 and get that 250w system with a hortilux upgrade.. and btw you did the rastafan right, Sometimes when temps creep up in the summer I cut the front of the bag so I get more direct airflow to my plants.. peace and good luck with your girls

oh wait your in uk... i would say order from the doc but do try to find an enhanced spectrum bulb they make a shitload of a difference
