I do a cold frame. This was my first year & I was very happy with it. Being a zone5er it sure is nice to get an early start & extend the
growing season a little. My cold frame consists of an aluminum frame, more or less a portable car port frame covered in 2 layers of 6 mil poly film. I started my
seeds a month earlier than usual with great germination results. I have had to use a small ceramic heater to keep the temps up during the month of march, but there hasn't been heat in there since & all is well. I have nice big thriving
plants to stick into the ground as soon as temps stay consistantly warm around here. This will be the first year I haven't had to start from
seed at the end of May & the first year the nursery won't be taking my cash for
plants lol:)
My husband has finally agreed to build me a full on heated
greenhouse this summer, so next year will be the happiest gardening year of my life & I just can't wait. We are going to rennovate a large wooden shed, more like a small garage, into my
greenhouse. He is going to remove the roof & then half way down the walls all of the siding. We are covering with polycarbonate panels & leaving a knee wall. I simply can't wait. I am so ready to light a fire under his bottom & get him out there & started.
Good luck to you!
