i topped it right after its 4th node.... and i only topped it once and it gave me four new main colas both times i have done it so far.. as for the lights they are 42 watters which is equal to 150 watts and 2700 lumenz and i got four of em so thats about 10,000 lumens all together..im guessing its ok untill i can save up enough to buy a 250 hps

and it took me about four weeks to get it to look liek that.. they grow pretty fast with the cfls.. im pretty amazed at what they can do ...
