looks good mukker, cold temps maybe i little low but i dont think it should have too big of an effect, typically you want between 70 and 80f , once the seedlings start opening up youl see the difference daily, unless your like me and spend 23 hours and 45 mins a day in the grow tent the whole way through till you switch to 12/12 then spend 12 hours in it and the other 11hrs 45 mins staring at it in darkness waiting for the lights to come back on, how big is your grow area? after this grow it wont be big enough, you may have to move house as once you start you really dont stop, weed isnt addictive, growing is lol
Ok i will tell you my secret on what to do for that 11hrs and 45 mis of darkness. Go get the glow in the dark green stars and moons stickers and put them on the roof of tent. Then you can lay in there and look at the star's and smell the sweetness. SHHH do tell anybody else the secret.
