I live in a relatively cold damp climate. For most of the year temps are about 6-13°c 50-70% rh . Apart from.summer which has been exceptionally warm this year highs of 32° . But that's been brief it's already back down to 14° .
That said I know LEDs throw out less heat than say cfl. And I know with my very first grow inside a small bin using a 100 watt led instill could have problems keeping heat in especially at lights off . I started that grow during winter so i had to run my autos 24/7.
This time around I want to give the plants some rest, get some stretching between the nodes or just less compact , and save on the energy bill.
So
A) will a 480w ( not using full power though about 300w max) provide enough heat to a 120x120x200cm(4x4) grow tent . I will have an inline fan , potentially reducing to 50% , and one oscillating clip fan inside and either a passive intake or a diy setup using pc fans and duct tube. .
B) with lights off . Should I shut down all fans but the oscillating clip fan for the 6hours of darkness . Even with that. Concerned about temperatures dropping.
I don't use central heating and my apartment is around 16°c most of the year apart from winter months it's about 13°c.
Previous grows I've grow out of bins in cupboards and insulated heavily keeping the heat in until lights off . But had no fans running to achieve It.
So a few questions here
Will led throw of 300watt throw out enough heat while providing efficient CO2 exchange . Can I take it down a notch to keep the heat .
And what should and could I do for lights off to keep the heat in and potentially shutting down all fans but an oscillating one when lights off
