Thanks man so I should leave in darkness after sewing the seed

like this one on e-gay eBay.ie: T8 4ft Fluorescent Tubes 36w Daylight 6500k (item 180611459002 end time 10-Feb-11 10:28:39 GMT)

btw it's a closet grow set up I'll get a pic up next week
The bulb I have is 600w but I think it's a hps light not sure, can you tell by apperence??

Can I use this for vegging?
