This is why cfl's are great, you can put them 360 degrees around the plant and really close. I used 42 watt warm cfl's for all stages and kept 8 covering the 3 girls from all directions, 3 inches away. A lot of cultivators hate cfl's because they believe they don't work but I've used a lot of different lights including Led, HPS, MH and all kinds of different spectrum bulbs. So far I like cfl's the best for closet crops because you can get close with no worries of heat or burn.
Just put new cups (not clear ones) under the clear cups, you'll be fine.
I do recommend using HID's but only if you can afford them and do it right with a cooling system.
What are you going to use to control the odor?
