I don't have a greenhouse, but want one next year. I'm curious, when it gets down to the 20s at night.

I've gotten this far with a small electric heater here in MN. The forecast is calling for subzero temps and even my heater won't be able to counter that. I could insulate but I don't think the cost to continue heating is worth it.

I can barely afford to heat my house, let alone a green house.

I have a Harbor Freight 10x12 and use a small electric oil heater. With good daytime heating and minimal opening, I can keep mine at least 10-15 degrees above the outside temp. That’s been good enough for container peppers and tomatoes.

You have to have heat to stay warmer then outside. I’m in Michigan and keep mine around 50 degrees at night.

Unless the greenhouse is heated it won't be more than a couple degrees warmer than the outside temperature.

I'm in Ohio and when it is in the 20s outside, without running heat; it's 18 to 20 inside.
