If anyone has any tips it would be greatly appreciated! This is our first winter with a greenhouse, my father in law gifted us a VEVOR walk in 15 x 7 plastic cover greenhouse. Very sweet of him but not the choice I would’ve gone with myself, if I had the money I’d splurge on a glass one. I mostly keep tropicals, herbs and house plants but I’ve got quite a few smaller banana and avocados trees. Everything was great this summer with the greenhouse, so for winter I bought a small electric Utilitech heater recommended to me at Lowe’s and I have some grow lights coming in the mail. I’m starting to worry the heater isn’t enough, it gets plenty warm in there, into the 60s which should be fine for all my plants, but I feel like it never gets super warm in there. I’ve noticed many of them browning and dying (pics below) and I’m starting to wonder if I should just bring everything inside for the winter. I’m scared so many are too far gone and I can’t tell if it’s from being to cold or getting too hot, the heater is far enough away that I didn’t think it would burn any of them but some do look almost scorched. I’ve still been keeping the humidity up as well but not enough to kill this many plants. Should I get a thicker cover for winter or maybe a diffrent heater? If anyone has any advice please let me know, it would be greatly appreciated!

60s are the overnight lows in the greenhouse? Where is your thermostat located? Greenhouses can often have cold spots away from the thermostat that don’t get accounted for.
If the heater can’t keep up, you need to add more insulation. This time of year, your north wall should be completely insulated with something like R13 foam board. If it still can’t keep up, a larger heat source may be required.
Were all those plants outside this summer? Some of the damage looks like sun burn, as if the plants went from low light inside the house to bright outside sunlight without a transition period.
