So here is my cab. It started as a dual chamber veg and flowering cab, This lasted for the whole of 1 grow . The total dimensions were: H: 1m W: 1.5m D: 0.8m Veg Cab: H: 1m W: 0.6m D: 0.8m Flowering: H: 1m W: 0.9m D: 0.8m I was using a 250watt in the flowering chamber with a cooltube reflector. Now I have flipped it on to its side and the new dimensions are: H: 1.5m W: 1m D: 0.8m I have upgraded to a 400watt light and I am still currently using a cooltube. I wont explain my whole setup as the pics speak for them self. To see pics of the flowering chamber please check my last grow in my sig.
