sorry everyone. i had an insanely extremely close call with my landlord. i've gotten rid of all the plants, clones etc. and i'll have to start again from seed once this blows over/once my heat starts working again! i'm not a bad guy, i just wanted to grow a few plants. unfortunately my landlord might not see it like that..

but there's some really good info in this thread. thanks to everybody who posted i'll be back!
