welcome to cann.com.

you can't really have too much light. the more the better (unless we are talking fresh cut clones). you want a minimum of 5000 lumens per sq ft.

they will grow, although a lack of light might cause problems. are you using CFLs or fluorescent tubes?

either way keep the lights within 1-4" for best results. you might want to back the lights off of the mazar with the root damage.

good growing!
