Dawg days

Hi everyone. So finally fed up with the hassle I’ve decided to have a go myself at a grow. I am an entirely new but determined to do the best job I can so with that in mind if anybody has any advice or comments throughout my diary then it would be most warmly welcomed. So a little about the set up. A 70 x 70 x 160 tent with MH 4inch fan and SF 1000 LEDs. I’ve put a little heater inside as tent is in outside insulated metal shed and a small hanging bag of Co2 pierced with 3 holes. I have a fan ready to go for air flow but holding off just yet as she seems a little delicate at the moment. Running an 18/6 schedule with stable temp of around 25c during the day, tailing a few degrees when the lights go out and a humidity of around 65%. Planted 2 seeds, a dawg and the free kush I was sent but the kush didn’t appear to germinate. I think I may have drowned her with an initial over exuberant watering by mistake. I eventually planted a fresh dawg into the pot and kept it under lights from the start and around 3 days later my second beauty appeared.
