T12's

How many plants could i put under 2 40w 6500k 3050 lumens T12 lights?

Good for rooting clones or the first 1-2 weeks of veg but other than that you will need a lot more light.

Ok cuz ima noob so i was just curious if i could do full veg with them cuz they are a cheap option. Thank You for your reply!

HO T5 is the way to go

I might just go all out and get a 400w HPS/MH convertable.
