nice vid, I like the songs too
Weezy F Baby = Best rapper alive.
but yea the plants looked really stretched and very small for 18 days, I'd probably use the just CFL's for the first weeks of Veg and then add the HPS a lil later.
Get the fluoro's as close to the plants as you can without burning them and you might need a larger oscillating fan set on low for a little stronger breeze...
that could be a reason why the plants were so small. CPU fans are usually used for ventilation, if you were using the CPU fans to suck in new air and exhaust old air they would be fine, but you'll need something a lil stronger to develop thicker stems and help the plants growth, so you'd probably wanna get a new fan or add more CPU fans.
