Best way to heat a small room?

[GpsFrontier]

Heating pads might do the job in that small of a space. You don't want the water temp to get much above 70 degrees, but the air temp for the tomato's should be in the upper 80's. I might also suggest using a small room oil filled radiant heater like this: Electric Oil-Filled Radiant Portable Heater. However with a space that small it might be hard not to over heat the space. But they do make some with a digital thermostat built in, though those are more expensive. Also you can always try and increase the air ventilation to compensate by bring in cool air, and another possibility is setting the heater on low and using a timer to turn it on and off. You can also use a heat lamp, but it will over heat the space as well unless you regulate it's on/off times. Also with a heat lamp you would need to be very careful in where you put and how you set it up, or you could cause a fire.

I'd rather not have a heater like that. It's a small space and I'd fear something catching fire.



The human heat pad got the air temp from 55 to 57 in 5 hours.

It's 7+ years old and has had some use so I think a new one made for plants would do better.

I used 1 of these 2 years ago during the winter months.

Sunbeam Ceramic Heater: Heating, Cooling, & Air Quality : Walmart.com

I had it hooked up to a timer it would go on when the grow lights turned off. It kept the grow area warm at the same temp as when the lights were on. If I hadn't used it my plants would've died from the drastic temp drop.

Found a larger version 105w Amazon.com: Milliard Durable Waterproof Seedling Heat Pad 48"x20": Patio, Lawn & Garden

The 53w raised the air 3~ degrees I think a 105w should do 5 to 7 degrees (60-63 at night 70-75 day).

/ordered the 105w if it doesn't work I'm sure I'll use it for something else.

Update in case anyone was wondering.

With heat pad at night 66-68
With heat pad at day 75-77 with a small fan on probably 77-80 without the fan.


hydroponic buckets are half way on the pad with air pumps out side (cooler air) water's 68-71.
