Best method for heating small grow tent

Hi Everyone,
I've been a lurker for a while and finally decided to make my first post! After two successful runs of doing the pf tek method in my closet, I decided to set aside some space in my house for a martha grow tent.
The temperature in my house during winter is ~63F so I want to raise the temperature in the grow tent to maximize growth potential of the mushrooms. I've thought of a few ways to manage heating up the tent without heating up the surrounding area too much.
1) using a heating lamp over some moist peralite 2) using a heating pad over some moist peralite 3) using a space heater to blow into the grow tent
All methods would be regulated by an inkbird temperature control to make sure it doesn't overheat in the tent. I'm a little cautious about using a space heater as I don't want to waste electricity heating my whole room and that I don't want to melt the plastic lining of the tent.
What are your thoughts? Are any of these options viable? Do you have any other recommendations outside the ones I outlined above? Also, do you recommend two different temperature cycles throughout the day like 75 degrees in daylight and maybe 65 at night?
Have a mindful and wonderful day, Cowboy

I’m not sure what exactly you mean by ‘space heater’, but if you’re thinking about these little hot-air blowers (basically like hair dryers, but with a stand), you have to consider that they not only warm up their surroundings, but also make ambient humidity levels drop. I wouldn’t use them for that reason. But there are others, without a fan, that could work. I don’t how big your tent is, but for my tubs I’m using a heating pad, and I’m getting much better results now. A heating pad or two will be much cheaper (consumption wise).

So when you are trying to artificially heat things, the idea is to raise the ambient temperature of the grow area/room. When you directly raise the internal temperatures of your jars, you run the risk of drying out the substrate, which could cause the jars to stall. If the space heater is powerful enough to heat the entire room to a nice temp, I'd use that. Maybe invest in a humidifier if you are concerned about humidity being to low.
You can have success with using heating pads on the jars, but maybe put them on low setting. Temperature effects growth speed, there have been people who have left jars in a freezing garage during winter that finished colonizing months later. 62 degrees is not ideal but its not bad, might just add a few weeks.
I would keep temps as stable as possible, temperature swings can increase contam rates.

Try using monotubs. Temps inside might hold better than Martha. A regular small heater or radiator with a inkbird outside the tub/tent shld help

If the house temperature is 63, a good healthy substrate should be a 65-69f, which is perfect for quality cubes.

In my own (limited) experience, once room temperatures dropped below 70F, yields were substantially smaller, and I got lots of aborts. I’m sure it’s also my fault, but could it be that everything else has to be near perfect, if temperatures are below 70?

What do you think about the idea of putting an aquarium heatlamp in the same external tub that is used for humidity?
It would be attached to a thermostat of course and, if necessary, make the mist more... steamy. Catching two birds with one stone.
I'm about to start a grow in a 1x2 square meter (4cubic meter) tent. (check out this thread )
The external humidity tub (which I have yet to make) will not always create mist. And I don't know how often it will be running.
So the heating (if done via this method) would also only happen when mist is produced. And when it isn't, the water would be heated with no effect on the thermometer inside the tent. (Unless I would find a powerstrip that somehow requires both the thermometer and the humidity meter to send signals... not going to happen)
And perhaps there are other problems that I'm not seeing and it will harm the growth.
-- If this is not a solution - then what would be an efficient heating solution? A infrared heater? or a mat?

Another vote for turn up the thermostat. Get it to at least 68 and you should be good. I keep my house at 72 because that's my shroomies favorite temp but my wife complains it's cold so lately it's at 74.
