Yeah, it gets even a bit colder at times outside, so I built a gassifying stove (for about 50 bucks out of some old army barrels. I have lots of woods on my property, and a chainsaw and an axe...so it didn't really cost me much)...you have to work with what you have, and do what makes sense in your set and setting.

<p>Gotcha. </p>

<p>Keeping mine above freezing where I live would be very expensive. As it is, it gets down near 0 degF (-17C) in the greenhouse on occasion. I can improve that a bit but I'm not willing to go to the expense of improving it a lot. So I'm left trying to figure out how to keep my plants alive at very low temperatures.</p>

Sometimes it's a struggle just to keep the air temperature above freezing...but it fluctuates with outside temps.

<p>Is it worth ventilating at night? I know transpiration is much faster in the day. Does it matter if they can transpire at night when it's cold out?</p>

Wood heating is drying, propane adds a significant amount of water vapour in the air...<br />
Spinach can take some slightly below freezing temps, especially if their are some salts in your system. It uses the salts present as anti freeze. So don't get freaked out by the guttation you see...many noobs will think their insect eggs or other funky stuff.<br />
Yeah they do need to transpire, so you prob don't want to seal everything up and not ventilate...in which case I believe you'll notice fungal problems…

<p>Wow - thanks Vlad! I appreciate it. I'll see about getting some of those fungicide/buffering agents. My water pH tends to run high anyhow. That might be helping me it seems.</p>
<p>So... fungus in your opinion is the major problem. You don't see any special issues with cellular destruction from freezing in a high humidity / zero transpiration environment?</p>
<p>Or some kind of oxygen depletion? I've heard it said that "plants need to transpire to breathe." I'm not sure what that means…</p>

<p>I'm curious why you say that propane is drying while wood heating is not. Don't they both involve the same combustion process (i.e. CxHx + O2 -> CO2 and H2O)?</p>
<p>A tiny HRV would be awesome, if I could find one. Or something like a heat pipe or thermosiphon.</p>
