last year i grew two plants under cfls then i had to get them out of the house so i started growing them outside still in pots but not on my land one turned out to be male on female, inside i had given them an amazing life of all they wanted lol i mean nutreins and stuff but i took them out at a month and 1 week ish and once they wheree outside all i realyl did for it was kill of slugs with pellets and give it nutreins every now and then in small quantities, i eman this was like a 1/4 of the dose eccomended a a week but a few times a month lol so the plant was very deprived of it all and still yielded a buetiful ounce and a bit...

you know what, it was the best weed i ever smoked it was worth it.

but this year i know that with a bit of attention and care (nearly added love in their but thout it sounds too sissyish ) i can get at leats twice that amount per plant.

anyway i would say for q3and4 i would that i reccomend buying some plant nutrients (fertilisers) and feed it to them not too soon about after a month or three weeks old is when you start feeding, also introduce it slowly, thats the very basics now i would suggest read this site more, look in the faq read up cos i really cant tell you everything here and its good info lol...

good luck
