i got a 250cfl for like $40...not sure how much or the seperate bulbs cost u plus adapters etc but might b cheaper ? :/ and for gettin to lower buds u can either train them slowly so they stey out more and/or paint the walla in a bright white that wont pollute the air or cover in reflective sheeting. the cfl's are self ballasted too, so its literally just pluged into the wall and u dont have to worry bout balast overheating etc or getting humid. food for thought ! good luck though they look healthy i hope u get some nice smoke
