Building a greenhouse here in NE Ohio Snow belt.

20x12
Mostly hoop with dual layer 6 mil plastic
Completely Solar Powered (to easy to use grid electric)
750 gallon possible fish tank in ground (Aquaponics)
60,000 BTU Solar Pool water heater

Attached are a few pics.
Humidity way too high inside, so I covered the fish tank with plastic and am trying to get the water off the plastic.

Also need too add heat, planning on using an old 20lb propane tank as a boiler to heat water in the FT

Notice the solar powered well? I used two wiper motors to push the handle up and down,,, filled the FT with well water.
But I stole the two solar panels from the well and hooked them up to the GH, as the FT has a 12 volt bilge pump to pump water through the panel.

Cools the GH when it gets hotter then the water in the FT, heats when the FT water is warmer.

Here's the weather I was working in before the GH got covered. Oh and there is a Grapefruit and Lemon inside, so I NEED to keep it warm.

It's a fine greenhouse.

I like the solid north wall.
There is no sunlight coming through it, makes sense to build solid and add insulation.

The 6 mil cover is a cheap option but it won't last. Expect maybe 6 months. The UV will make it brittle, then it will tear easily. It should get you through the winter.

The center roof support looks solid enough to hold hanging baskets.
Good support for the cover. What sort of wind do you get in the spring? What did you use to secure the cover to the frame?
I think if the wind gets to be strong, additional strapping for the cover would be in order. I'm thinking rope thrown over the top every couple feet would keep the plastic from flapping.

Lots of humidity inside these things. When I built my first greenhouse, it had a visqueen cover. I was impressed with the rain indoors every time I opened and closed the door.
You might consider offering the frame some water protection.

In the third image, I am not able to identify what I'm looking at.

Keep up the good work.

The third pic is a tomato plant that was transplanted from outdoors. The bell pepper I transplanted seems to have taken hold. The cayenne (potted) is doing fine, as is the jalapeno.
Planted a couple beans next to the center pole, and some lettuce

Will take more pics as it progresses.

The plastic on the hoop is greenhouse 6 mil UV resistant plastic. The sides is plain 6 mil from lowes. I plan on taking the sides down when it warms, so I wasn't concerned about durability on the side plastic.

completely covered the fish tank and built a little walkway so that I can access the batteries (which might get moved outside) and the bilge pump.

Here's a few recent pictures. I need to heat the water in the catch basin. So I'm playing around with copper tubing and cob. Was looking good until the cob fell off and made a mess, so I got an old bed sheet and wrapped it. It's still not dry, but I'll be burning again today.

I'm buring logs of sawdust/WVO that I make by wrapping about 1 1/2 of the mix in 2 1/2 sheets of newspaper. Every burn so far has been good, nice even and steady burn, pleasant smell too.

Until the last burn. I think I need to cut a slit across the top of the loaf before igniting, the last one didn't burn hardly at all, too much flat paper.

I got a back draft on the last burn, so I dug a little and pointed the air intake down. yiou can't se in the picture, but there's plenty of room for air to move.


Antoher thing, the tomatoe isn't doing well at all. Then moving compost around, I snapped the only nice branch left.

I decided to put compost over the roots of the grapefruit tree and all in that corner to cut down on heat loss.

Currently, I haven't put on any compost access doors, just holding plastic in place with a piece of wood and a brick.

Thinking is, and air that makes it through the two layers of plastic, will move through the compost, aerating it,,, wishful thinking, huh,,,

Picture time,,
