Hello all! This is my first post here. Love the greenhouses! I am in Salt Lake City, zone 7a.

We are going to convert a shed to a greenhouse next spring, but I need a place to start seeds to plant in the garden next spring.

I have zero room in my house to do it, so I thought we could make a very small greenhouse that would fit on our table just outside our back door.

(For size reference the table seats 6 people.) We have some windows we were thinking of using. It would get full sun.

I just don't know how to start this, or if it would even work.

Any suggestions?

Go at ground level - essentially build a box on the ground and cover with the windows. That's a cold frame. I am in Chicago (zone 6a) and start about 250 tomato and pepper plants every spring. In March I sow indoors in flats, not individual pots, to save on space. After about 4 weeks I transplant into individual pots and then shift to the cold frame. If we have a cold snap I can throw a plastic sheet over the cold frame for more temperature protection. If it gets warm I can tilt the windows open for a bit of air. It's super simple - I've been doing it almost 20 years. I see down thread you tried a cold frame but if you start indoors in March and then shift to the cold frame in the middle of April you will get better results.

Do you have a garage? I have started many plants on a shelf surrounded with foam insulation panels and lights. On really cold nights a heat lamp (like for chicks) does well to keep it warm enough inside.

Most of SLC is more like zone 5. If it’s that cold, you may have trouble keeping plants warm enough in the winter.

Use light rope to heat under the trays. Don't use led, use the other Incandesant kind.

The warmer the better for seedlings. Heat pads do wonders. I grow all my seedlings in a little grow tent.

If you have extra large wire dog kennels you would wrap them in plastic.

Otherwise “Palm Springs 2” is a brand that has something you might want to look into. It’s just shelves surrounded by plastic with a zipper door.

We are up in Wanship 🙂. Not too far from SLC.

Cover your seeds starts with assorted recycled plastic produce, fruit boxes … be sure they have vent holes.
