Keeping a room heated/cooled in Michigan durning the winter months

I am wondering how people in Michigan handle heating/cooling during the winter. I was planning on having a fresh air intake from outside but I am not sure if this is a good idea in a climate like Michigan. Worried about condensation when the outside air hits the air in the room. Also concerned about temps getting too cold. Thought about using the heat from the air cooled reflectors mixed with fresh out side air but not sure. Anyone have any insight into dealing with proper intake/venting and maintaining temps in the winter time?

Do you have a basement??

I run a Sentinel CHHC-1 to do the dirty work for me.

Use a couple of these while lights are off to keep your grow room warm and time them to turn off once lights kick back on.

Depending on how much room you have and the temp swings something as simple as a few barrels of water can help regulate temps.
If possible I think a closed room is the best idea, using outdoor ventilation is too hot in the summer, cold in the winter, and risks contamination. That won't make the need for heating/cooling go away of course.

Can you tell us a little more about your set-up, like what kind of gear will you be running, c02 enriched, a tent or a room, first floor, second floor, square ft, stuff of that nature will help to determine your best options. Are you close to a water-heater rent or own...

i got this really nice 8000BTU ac/dehumidifier/heating unit at sears for 300 bux....it works for my 5x5 tent..and its only 700 watts

13' x 8' room on a slab, partitioned into a 9' x 8' grow area with an insulated wall and door that could be sealed/air tight if needed. The cold air return and register are outside the grow area in the leftover 4' x 8' area. Inside the grow area is a cabinet 6' x 2.5', which houses 2 x 600 watt 6" air cooled hoods, a 6" damper on the ceiling leading into straight pipe vented out the roof, 2 x 6" flanges installed leading back into the grow area and a 4" passive intake. A 6" 400 cfm fan was going to be pulling air through a Phresh filter, blowing through the hoods and out the straight pipe through the roof. I would like the option to use CO2 or maybe heat the room with the warm air from the hoods which is why I installed the extra 6" flanges. They will be covered otherwise. The cabinet itself is sealed besides the 4" intake.

I got ahead of myself and didn't put a lot of thought into air intake and heating/cooling in the different seasons. Was going to use a 4" Dust Shroom filter on the intake of the cabinet and consider the air that leaks into the grow room under the door a passive intake into the grow room. But then I am left wondering how to handle CO2 if I go this route. Down the road I was planning on adding another cabinet or tent into the room and would like to have the option to bring fresh, filtered air into the whole room. At this point I have no intake into the room itself and I am kind of left scratching my head here. If I wanted to seal the room can I add a 6" intake from outside to blow through the hoods or would this cause too much condensation in the winter? Any ideas would be appreciated.

I find it best to intake from an indoor room that is ambent temp. Otherwise you're going to be pouring heat (and money) into that thing all winter and vice versa.

I actually have a heat duct going into my room from the furnace. My room is in the basement and that heat duct is currently acting as my fresh air intake. I was running 81'-85' last week but now that it is cold outside my temps in the room are 75' including under the light. I'm kind of hoping 2 things..

1. The furnace heats the room enough during lights out..
2. When the furnace is blowing air in there it isnt too much that it screws up my negative pressure and blows stink upstairs..

A little leak under the door won't hurt when running CO2. The biggest worry will be making sure your hood ventilation has no leaks.

For heat in the winter you have a couple different options.
Take your hood ventilation and draw from one corner of the room and vent to another.
If the heat is too high that route install a split T or Y fittings that have a dampers into your light ventilation pipe. You can adjust the damper as necessary to control the temps. This won't work with CO2.
You can vent into your home heating ducts to save on your home heating bill.
If you get a CO2 burner that will provide heat but you'll have to keep the same air in the room and you'll have to cool it in the summer.
For night time you may need a small electrical heater.

Sounds like you have summer covered.

i was thinking of using something like thishttp://www.homedepot.com/Building-Materials-Heating-Venting-Cooling-Heaters-Wall/h_d1/N-5yc1vZarpk/R-202882716/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053

I have a sealed room (basement grow) and in the winter time, I bring in outdoor air through 8" insulated ductwork into my 3 1000w lights and expel it into my ductwork to heat the house. In the summer, I still bring in the outdoor air through the lights but expel it outside so it doesn't heat up my house. It works for me. Just make sure you use the best insulated ducting so you don't have condensation problems, and seal the lights so you don't lose co2.

You'd be better off taking your air from the returns of your home heating system, or from some place in your home. Taking it from outside will displace a lot of the warm air that's already inside.

Use a couple of these while lights are off to keep your grow room warm and time them to turn off once lights kick back on.

do these ceramic heaters not glow at all? I had looked at some, but was unsure if they emitted light.
