Lighting T8 grow advice

[MrMann]

Hi all,

Ok I realize T8 isn't the best route but i managed to get my hands on BNIB 10 x 5ft T8 58W 4000k for next to nothing.How many plants could I grow with these and how far apart should I space the lights?
I can also get another 11 x T5's for extremely cheap and my thought process was to use one set for veg and the other flower. I'll be growing 45 day auto's

There is method behind my madness... My grow area is large but slightly less than 1m high, hence wanting fluorescent and I also realize T5 is better but it's what I got right now.

Any constructive input would be greatly appreciated

Thanks
