Anyone up there in the northern climes using cold frames to harden off the seedlings before planting to the garden?
I don’t really use a cold frame. I use something similar, except I use a row cover instead of glass. That way sun and rain gets through to a certain extent, and it doesn’t overheat or get sunburned.
I also have a side yard that gets a limited amount of sun, so I put a lot of plants from the indoors out there to adjust.
