ya man u got i monster on ur hands. theres lots of bud sites, cant wait to see wat u can do with a good strain. ya if u switch out 3 of the 6 bulbs to 42w 2700k CFLs u will see a big difference in bud size an weight, also them bud should frost up a lot. just remember to keep the heat below 90F. anything above that will make the buds really fluffy an hert your yeild an strength of the buds.you could try the 40watters on that site link u posted they wont put out as much heat( very little difference but helpful)an put out the same lumens. good luck
