Very nice!

Now if it were a bit taller and longer it could cover your window and let in warm air in winter through the window.

What's the cfm of the vent fan and where does makeup air come from? The only problem I see is that this can heat up quickly and it looks very tight. Do you plan to remove a panel during sunny days?

I see that you have some experience with GHs.
Indeed the thing heats up quickly. I ordered an extra fan just in case.

There is a vent port on the opposit end for cross ventilation.

All the front panels are easily operable because they are just hinged using tape and held by Velcro.

nice, quick set up dcarch, it is always interesting to see what MacGyver inspired structures people come up with. Great job.

Thanks, red_sea_me.

Making wonderful progress. Many blossoms forming on plants. Not bad at all for Z6/7 NY!
Hope to remove the greenhouse in the next one or two weeks. Depending on long range forcast.

OMG, I'm jealous. I have to show my parents these pics. They live in Westchester, me in CT and May 1st the plants are not even 1 foot yet. Meanwhile you have blossoms? Wow

Seeds were started 2/11
Seedlings in ground 4/1
Pictures taken 5/1.
Becasue the concept is working well so far, next year I will try starting seeds 1/11

My Father-in-law and I just finished a raised bed greenhouse.
We live in cold clay soil that does not warm til mid June but the daytime temps are quite warm as early as late April. So we insulated the bed from the cold with 2" of dense foam and placed 18" of clay soil over the top. Then we put up 4x4's up to about 4 1/2 feet above the top of the soil and built a frame. Temporary plastic goes over the frame and a door is built in the side to open as needed. It works! The greenhouse heats up even on cloudy days and the soil is warmed greatly! I have melons and pumpkins starting to get second leaves - unheard of around here! Actually, melons are normally an impossibility in this cold clay soil. The plastic will come off in early June and will probably mulch with straw around the outside to help hold water.

I guess no more frost. So I took down the greenhouse.
The whole thing took about 7 minutes to remove.
I will be putting it back at the end of the season to grow some salad greens, or may be some cold tolerent tomatoes.

I really enjoyed this project. No transplanting, No fear of frost, couple of months early. Most of the plants are starting to blossom.
It's great to overcome what mother nature dictates

I'm glad it turned out so well for you. I appreciate you taking the time to share the project and the process. A lot of time we never hear about the end results.

I have a temporary greenhouse over a raised bed in Zone5 NY. I will probably leave it up a little longer, I'm thinking June. I'll look forward to see what you manage in the fall this year.
