I'm going to set up a PC Grow box with car reflectors on the inside and cfls along with a DWC for my babies

2 seeds (White Russian Autoflowering) from SensibleSeeds (havnt ordered yet, any opinions?)

how close do the CFLS have to be? I plan on using 4 30 watt 6100k cfls
or can they stay at the top of the pc case? (apx. 18 inches away from DWC)

any suggestions are also welcome

What are the car reflectors for?

For the two little plants, I'd say those are fine for starting. Maybe grab a couple 23W 6500K ones too. I use the 6" and 8" reflectors, all individually hung and adjustable. I keep the bulbs a few inches above the tops. Don't forget to raise them a bit each day or two. Otherwise they will grow up into the CFLs and get singed. Only the parts of the plant in direct contact with a CFL for more than a few minutes will suffer.

Switch to 2100K, 2700K, 4100K for flowering. 4100K, 5500K, 6500++K for veg. I use between 9 and 12 23W 6500K CFLs (a few 5500Ks) for vegging in one room and I flower with LED in another.

Resinatious.

I am growing in a pc case so the car reflectors are to maximize the light useage
I an using an autoflowering strain so since they need 24 light can I stay on the veg lights? I am now thinking of putting 2 6100k 30 watt cfls above the plants with one 2100k 30 Watt in the middle of the two on top
then I would add a single 6100k 30 watt cfl in the middle of the two plants at the level of the DWC to light the underside of the leaves

here's my question now: since I'm using an autoflowering strain should I change the 3 6100k cfls to 2100k and change the single 2100k to a 6100k one?
