Small T5 Setup Few Questions?

Hey all i've set about a new project designed for auto's using an old wardrobe i had laying round and some spare t5 ballasts and fittings. So far i've got 6 36w 4ft tubes, fans, panda film, coco and pearlite. First question, although not my first grow, first time with these lights and medium. How many auto's/small (50-60cm) plants would these lights support? I can add a few more tubes on top and side if needed plus cfls if absolutely necessary. I've got some pineapple express auto's, lsd, pineapple chunk and blz bud beans coming, 5 of each, could i do three of the auto's and one or two others? Sorry don't know much about t5's, i use led's normally lol. Also, can osmocote crf be used with coco the same way as soil? I usually mix my own super soil or use this stuff but due to physical restrictions that isn't really realistic anymore so i've had to switch to the coco pearl mix, if not, any suggestions for a nute mix for coco? Thanks in advance everyone, ben

well youll get about a square foot of veg for every tube maybe a little less.. I like 50 watts for veg.

Well there's about 220 actual watts of t5's in i space 5foot wide, 2foot deep, 3foot high, i guess in general how many plants could they finish similar to seemorebuds 'buds for less' setup? Will mainly be used for auto's but will run some photo's through for about 60 days to sample aswell.

I use a 2' x 4 tube T5 to start all my autos....6-8 at a time but rotate them at 3-4 weeks to a tent....never let one finish under the T5 but they do great in the first 4 weeks....don't know why they would finish under T5 during the whole grow...perhaps a smaller yeild but very smokable...good luck.

Thanks oldreefer, i usually use led's and ccob training so a smaller yield doesn't bother me, i make up for it by perpetuating my crop for a harvest every 6 weeks. Do you still use mixed spectrum as with cfl's for veg?
