It gets about prolly below freezin, but just to try it first I ran the heater all night, it got like 19 degrees out that night and early the next morning I went down and checked and the temp was 60 degrees, w/o my light being in there!!!!Hope it'll bring the room temp up enough to do the job. I dont have anything on here bout keeping up with my pics of my plant....how do I do it...Im new and a lil slow, lol. I wanted to get out something else....I only had 1 seed that sprouted....just sum reg weed, for my first time want to see if I can grow garbage b4 I spend;0) Anyway I planted the seed in straight peat moss and the seed sprouted to bout 3 inches and I was reading how ur supposed to put like a lil of that in the bottom so I went and got sum organic soil, and repotted a couple days ago, when I did this I shortened it down to like an inch to let sum of the others I greminated to catch up, waiting for them to srout, put them in the dirt yesterday, hope they do, the others ones didnt. I know this is a lil ghetto, but for the germination process till they are bout 50-60 cm Im using a 15watt fishtank light.....it was working at first but now Im wondering....although b4 I had grown 6 plants and got them to the state of determining the sex and then got spooked and disposed um but I used my 400 watt MH light right from germination, and ran lights for 12/12 from the getgo, these plants seemed to grow alot easier.....what to do?????
