nostr:npub1uhyp2jpp5gwjqh7w52tlapdwssmycmxglw2dzavy3mas3sfr83rsv6y4d5 I'm not really worried about air gaps and stuff, you know. Those might slow down feat transfer, but it's not like I'll be losing energy anyways, since there will be decent insulation and wood underneath. And it's just a greenhouse so who cares if it's not very even. All i want is a thermal mass that will keep warm for a while if there's a power outage at night in the middle of winter ;)
