if u wanna do it right, buy your stuff first then plant your seeds. Those ones r probably gonna die soon, but i dont think you run out of beans yeah?
1 if this is a domestic light bulb, get rid of it, it is useless. Get some cfls (fluorescents, tubes or bulbs) at least 100W for veggin and a 250-400W hps for flowering (you will have to get a fan or 2 to bring the heat down and circulate the air).
2 get rid of foil it is more like headache and it is of no use. Plaint the whole thing white or put some myllar on the walls.
3 get RID of that mirror, reflection will only bring the heat up and burn your babies, that i dont think they will ever crack the soil under those conditions.
Growing cannabis is easy, but tou need to go buy some stuff BEFORE you plant the seeds. And also, make sure your grow space is light proof, on 12/12 no leaks are allowed. Take a look at the boards and decide if you r willing to pay some money to buy the right stuff to get some bud, coz with what you have they wont even crack the seed. Bulbs, Fans, Pots, electrical stuff cables and timers, fertilizers and soil will probably run you from 250-500$ to grow properly (no proffecionaly, just properly) depends on what you buy and where you buy it from. Good Luck
