Hi guys, quick question.. What can you do to stop temperature fluxuations in your grow room, when your extracting the air from outside the house (open air)? Surely the outside air temp is going to be different in the changing seasons?
I ask this because, in the flowering period, it is very important to keep the temp stable is it not? Otherwise you get the "homie" taste and smell to the bud..
Is there a temperature controlling fan on sale?.. Which keeps air drawn into the grow room the same stable temp??
Or is it such a minor temp change in-betwwen seasons, that it doesnt really matter?
Fingerz!

there are fan controlers availible

a primair can adjust the air flow speed of the inlet and extract to keep temps in check

other manual methods would be to monitor the temps yourself and adjust where your ducting pulls air from..as an example if you where a loft grower you may move your intake from the vented soffit to inside your loft space to warm things up abit or you could change the speed of your fans to adjust airflow.

Another way of controling things would be to setup a heater to maintane a constant temp in or around your grow space
