I can't really help you with this little information. on your thread with a video the video was private so i couldn't watch it. lol
I started my grow with 1 26 watt cfl 2700k then doubled that, doubled again up to 105watt and doubled again up to 210watt. what is the color temperature of your bulbs? I managed females and decent growth with 2700k but you want around 5000k.
Idk about PC growbox but my plants were pretty much 12-12 from seed and would have out grown a pc case by now.
But yea go ahead and use 2700k light for veg. I didn't have much problems from it, but 5000k area would be better.
Also, for future posts make sure you use pictures because you're more likely to get a response.
