how to heat a room when lights off?

Hi
Does anyone have any tips of how to heat a room when the lights are off. I have placed a heating pad in the room, one of those seedling heat mats, it helps a little, they are costly, and use some watts, any ideas besides a little heater?
thanks

 

Don't know how big your room is. Small electric radiators work well. Good even heat.

Plan b would use regular old heating pads if the room is tiny. Lay them out flat so they radiate the heat up

You need a small fan to keep the air stirred up so it doesn't settle into layers and make the floor cold. Even a fan from a computer will work in a closet sized room. Put it near the ceiling.

Also, try turning off the fan that sucks air out of the grow area (when the light goes off), so more cold air is not sucked in, lowering temps.

 

just cover the plants with a light cloth at 'night'. there's an insulating foam blanket used in the nursery trade or a floating row cover.

 

How cold does it get?

 

I am with Bob here. Supplemental heating depends on the temps encountered. If the temps are going into the mid 60s ('F) you are fine. Explain your setup a bit. I do not like the idea of using a heater or electrical blankets - safety and paranoia.

If you are using a hydroponic system the feed tank can use a fish tank heater.

 

Bud, I have a question. I have a similar question about room heating. If i were to grow in the garage (which can fall to anywhere around 10 degrees F), do i need to heat the entire garage, or the plant itself? I've heard you can use a hot plate underneath your plant to keep them warm??

 

10'F? that is way too cold. The plant uses water to transport the nutrients and that is way below the freezing point. It would be better to frame off a small grow area, insulate it (insulation board - so you can use the reflective side) and try to heat the smaller area.

You can let the temps drop into the 60's with the lights off but with the lights on temps should go into the ~70'f range. Cold temps slow growth too btw. It is important to keep the pots/grow medium off the concrete floor so to keep any heat from being wicked out.

I would not want to have the plants on a hot plate for safety's sake. Paranoia about fires is justified - so if you were to use supplemental heating (electric for example) be sure to use a quality unit.

Its tough to use a garage in the winter. You can always begin indoors and move them out to the garage when the weather is more favorable.

A garage in your cold weather climate could be very problematic in winter. You would have to have a serious heating unit to bring it up from 10 degrees to 75, which means adequate wiring, a good thermostat, exhaust and on and on. One mistake and you're cooked ( or frozen ). I looked into something similar but came to the conclusion that there were way too many things that could go wrong.
