it did help my question but i dont know how to give rep :$ i plan to veg for 3 weeks i bought seeds i have no experience in as i thought i would learn more that way by just researching ( 3 months so far ) and tackling problems as they come using this site for the record the seeds are nirvana blue mystic and nirvana indoor mixthat ? is wayyy too vague. It all depends on how long you want to veg them first. I mean hear is an example; you could take 3 ft x 3 ft x 6ft tall space and grow 5 plants but you would probably want to start flowering at 12 inches or so... or you could put one 7 gal pot in that same space and veg one single plant, top it a couple times, vegging would be like 6-8 weeks and you would get the same amount of pot as 5 plants with one huge one. In other words you can use any size space you want (except too small, pc case) and just grow your plants/train them to fit that space. It's a guessing game basically until you get good at growing, I'm going through it right now with my plants, I'm going to wait a lil longer to get the size I think i need for my space. Did that help or answer your question? +rep never hurts
