Northern Lights Auto Tin Shed Grow

Got myself a new light the other week, thought I'd do a quick auto before the summer heat hits making it impossible to grow in a tin shed. As per all my Tin shed grows the environment is never ideal, I normally do during winter so cold temps are always a factor. Just manage it the best I can with heating bars but when nights are cold, as last night was close to 0 I'm lucky to maintain the temp of the tent any higher than 14-16c. Oh well, a nice quick easy soil grow this will be compared to my last where I used coco coir
