iv always wanted 2 grow weed but want 2 know exactly what im doing b4 i start. i live beside my grandparents farm and iv found the perfect place in the loft of a farm house for my grow box. just a few questions:
do you only have the fans and exhaust goin when the lights are on or 24/7?
my grandparents obviously will be paying the electric bill so can any1 give me a ballpark figure for the cost of say a 400w hps and 2 fans for lyk 9 weeks? for eg £40, £80 £150 i have no idea!
Also i live in ireland the loft is basicly the same temp as outside except for being wind proof! when my lights are off will i need a small heater in my grow box?
