Lighting questions!! ScRoGing

Hey guys...

My freind came across a wicked nice warehouse shelving unit..its 4 feet long by 2 feet wide and a litte over 7 feet tall/..( not bulky at all) very simple...closer to 8... With this we have 5 very heavy duty ajustable shevles that move along the way...with this being said...

what light source could u use if you wanted to do a scrog with multi layers...2 maybe 3 tops...as of right now were thinkin T5s with leds or even hps but dont see that as an option... the room is 8 by 4.5 with 9 foot clearance..we would even have room for a second one if he dared..that would be crazy..as for the plants, he has Bubble gum and AK on the way with white widow clones coming soon...

for vent we are goin to be runnin a 6 inch in-line fan to draw the air out...

Any info would be great....

has anyone used those huge floros screw in light bulbs?? something like that might be an option or a complete led grow setup but thats goin to be costly but worth it in the long run...power and bulb life...
