Ah, nice plan! Cheers TaNg!
Hey man, thanks! Yeah when I started looking into growing I was amazed how much it had changed since I helped a mate grow a couple of plants years back. Being able to use only 75W and get results in 11-12 weeks is incredible!
Cheers for the tip! I have a bit of a headache on this as the tent is in my insulated but unheated loft. I left the loft hatch open overnight which has helped (range between 24 and 21 now) but I'm wondering if I should add a small space heater on a thermostat to the loft to keep the ambient temperature a little higher and get the tent up to the range you suggest.
A small tube heater or a CFL will add heat bro.
