Sorry to hark on about this point, but the plants sex is of the utmost importance if it's female all well and good if it's male it's no good whatsoever and needs to be thrown away and you'll have to start again.Growing from seed can be a bit of a guessing game even with feminised seeds(had shedloads of trouble with em).The first seeds i ever bought (N/lights) out of the 10 50% turned out to be male and had to be thrown but what was left was pure sensi(unfertilised females) yielding great bud and perfect for cuttings for the next generation of plants. glaeken is right ,your light will probably be your biggest outlay so £150-200 might seem alot at the time but once you've got your first 4-5oz safely stored away,the next crop 2 wks from flower,about to spark a J of D'erb grown by your fair hand, and knowing you've just taken the biggest hassle out of the whole smoking experience ie:dealers and delivery times(no offence to those reading) as the man says it will "seem like a very small outlay". But again, learn how to identify male/female plants ,look for small pollen sacs in the armpit of the branch/stem they actually look like small testicles though mine are bigger lol anyway best of british
