Was wondering if anybody had any advice for someone growing in an UNHEATED but insulated building
in the cold of winter wth regards to ventilation. Were talking cold--high in the mountains cold--and probably only want to ventilate enough to get rid of stale air.
Specifics:
BUDBOX or similar (3ftx3x6ft) portable tent.
400w mh/hps depending on stage (no veg room yet)
CO2 enrichment to be used.
exhaust/inline fan????????????????????

was thinking about using a normal inline exhaust fan from home de pot because cheaper and more importantly less CFM's--can buy a fantech for summer if necessary but usually the room temp in this building is 60ish for 2 months and much less the rest of year

or is this just not going to happen in the cold of winter?

or if in this case an upright freezer with its normally unwanted insulation the best solution (and would be cheaper=freeish)
