smallsolarI have a #coldframe made of perspex and wood which due to its location gets a lot of sun in the morning, I've added some temperature sensors and it can get temps of over 40C at times, this is only for 30-60mins and then it gets a bit of shade and cools down.
I'd like to try and take advantage of this burst of heat but spread it during the day - so Mastodon friends - would adding some thermal mass help, perhaps a plastic bottle of water painted black?
What's nice is that I have sensors so should be able to monitor effectiveness!
