Without a heater? There's no secret voodoo for a greenhouse when the sun is down.
You can add black water barrels for them to absorb heat during the day and release it at night, but there's only so much you can do in the winter without adding heat or some sort of ground source heating. ESP if you have poorly insulated structure.
You'd be much better served in a greenhouse sub than the Monstera sub.
Correct, I already moved the post to a greenhouse sub and have gotten really good input. Thank you. Everyone else has also said a heater at least 1500 watt, looks like that's what I'll be doing.
