Winter air conditioning will clean, heat, and add moisture to the air. Year-round air conditioning will clean and control the temperature and the amount of moisture in the air throughout the year.

With a sealed room, it will (or should) be only "summertime" in there while the lights are on.

But,if you use an air conditioner in the winter it won't work that way! It works in an opposite fashion. Esspecially when there is an HID lamp fixture in operation. Just think about it... When you walk outside,in winter and breathe and blow your breath out you create condensation in the air. Same thing happens on a smaller scale but moisture still accumulates.

My room is a sealed room too. Not using co2 at the moment,but it is ready for it to be used..
