Lol! my first ever grow i did in small wardrobe & used 4 domestic CFL's totalling 54W - did 4 plants with 3 weeks veg & got probably just under an oz back in total. To be fair, i reckon there's no reason i couldn't have got abit more weight still, as theres a fair few things i couldve done better & 2 of the plants were CheezeWreck which seemed to be a well finicky & delicate sativa; both end up like palm trees with no lower foliage & just 1 big bud at top! Lol!
So yeah, u can do it with very minimal light, but it does also involve alot of re-positioning lights, bending leaves, etc most days, so does drain ur innovation & attention.
But most definitely overall, the more light the better - CFLwise i'd say 100W per plant is good measure for decent average return. Ideally buy loadsa 20W or 25W, etc, as then u can position them all around the plant & get close in, which is arguably more effective than just having 1 100W bulb hanging directly overhead. Tho multiple bulbs can be a pain, as u gotta find loadsa clip-on sockets cheap, and/or think out some way of safely positioning all those lights so close. It can be a challenge & u do end up with loadsa plugs too, which can mean buying a few 4-way gang plugs too!
Either way, i'd say ur best bet is just to give it a go with whatever u can get. Start it going anyway, as any amount of light will still grow it & u can at least practice keeping it healthy & hardy and practice attending to its needs. And u can always add more light at any time anyway.
now this is deff a noob question.. lol could you use any tent? or a tent specifically ment for growing? lol
