Northern Lights Auto - 2nd shed grow

All set for another shed grow now the temps a dropping. This is another tin shed grow and they certainly have there challenges. I thought I would waterproof my shed, unfortunately I sealed the outside not realising that run off channels run down the panel, I effectively stopped all drainage and due to a shipload of rain the last few days it's wet inside. Lucky I have my tent raised. A problem that will certainly need to be fixed prior to flowering, for now I'll just make sure I'm wearing my gumboots.
