First of all I have to say this site is wicked and I really like the community spirit.
I have started my first grow in a cab with the following dimensions 65cm x 70cm x 30cm. I have 2 CFL lights namely a 125W red / 65W blue mounted directly in the top of the cab. I have 2 intakes on the RHS in the floor with PVC elbows for a light trap. I have a 4" inline TT fan as an extractor fan hooked up to a carbon filter situated in the LHS just above the cab in a wooden box attached to the top of the cab.
After having issues with the temperature I have decided to feed in an intake directly from an air vent in my grow room and this has enabled me to get temps of 81-85F just below the lights (this is where I want the plants as I don’t want them to stretch at all !)
I have one LR2 that is 7 days old today – See pic below – They are feminized seeds so I am pretty much guaranteed a lady.
