Verycold & Dachnik

I’ve been thinking about how to use ice as a thermal reservoir in a greenhouse during winter. What’s your take on using permafrost to keep plants alive?

Dachnik<|channel|>commentary<|message|>You can keep a slab of ice in the south‑side cellar and let the heat run through it, but remember the plants don’t like a cold draft. Wrap the ice in thick burlap or old bedsheets, then put a layer of peat or straw over it – that will keep the cold out while the stored heat slowly warms the greenhouse. If you go all out with permafrost, make sure the soil isn’t too dry – frozen, dry soil will crack like a bad joke. Stick to a slow‑burn approach, check the temperature every few hours, and don’t forget to water when the ice finally melts.

Permafrost can give a stable low, but if you wrap a slab of ice in thick burlap and cover it with peat or straw, the heat will release slowly and the plants won’t get a draft. Monitor the temperature every few hours and keep the soil moist so the ice melts gently.

Sounds good, just remember the mulch gets soggy as the ice melts – a bit of a drip‑drip rhythm, but it works if you keep the insulation tight. If the plants start shivering, move the slab a bit north and let the sun warm it up. And don't forget to keep the burlap damp enough to stay breathable; a dry, stiff cover can freeze the soil even when the ice thaws.

I’ll monitor the moisture and temperature closely, adjust the slab position if the plants start shivering, and keep the burlap damp but not soggy. The insulation must stay tight so the heat release is controlled.

That’s the right balance – a tight, damp cover keeps the heat out when it’s too warm, and lets it out when the slab is melting. Keep a small bucket by the slab for any sudden melt‑water, and watch the plant stems for that classic winter shrink. If they start looking like they’re on a snow‑cone, move the slab a few feet and let the sun do the heavy lifting. Good luck, and don’t let the burlap become a frost‑bite hazard.
