its important for those of us with short seasons or limited space to work with a season extender.

Seedlings can be started earlier and plants kept longer into the season.

For this A greenhouse is A must!


Have you seen the price of green houses ?

I had a bunch of cinder blocks that were dumped in my back yard. Enough of them I was able to make a 6x4 raised bed and have several left over. Also had a left knee window pane from a screened door and a roll of left over plastic.

Plastic on top of pallet used for my compost pile. Made a 3X3 square 2 blocks high. Layer of plastic on top and Windows pane on top of that.

Nice cold frame Bear.

My greenhouse is also built with re-appropriated hardware. The only thing new that went into this, was a couple of pieces of corrugated fiberglass roofing, and a box or so of deck screws to hold the whole thing together.

Very nice J.

I love repoirpsed materials like doors and windows used to make greenhouses. They have such a personal look to them.

oh yeah! smart use of that pane and blocks. it's loaded into the thread sideways which suggests the upright use of the blocks, which I take to be a good idea too.

 

Actually thought of making a solar dehydrator doing something quite like that. Glass front, wood back with wire shelves, screened top and bottom to keep the bugs out. convection should make for lots of air flow........

The cinder blocks are laying on side like they normally stack
I'm just having difficulty with my pics showing up in a wierd way.

I figure I'll go back and edit them later.

Crossing my fingers it got to 30f here this morning. Have not gotten out to see if my seedlings are ok. It's too nice and warm under the covers and the dog is weged between me and the covers over us. I'd hate to wake her!

I put out nasturtium and marigolds a couple days ago. They are fairly cold hardy but 30...we will see! Good news is I only put Half of them out.

I have thought of using a $50 metal bracket framing kit and use corrugated pvc or fiberglass panels. Could build a greenhouse quick and easy.
The framing kits can be found that use 2x2s or 2x4s. A guy can add automatic greenhouse vent openers ( I have several ) that are adjustable opening when it gets warm enough to vent. With a door to get in.

The framing kits are used to make shed and green houses. I do like the idea of recycling.

edit - gutters attached could be used to collect rain water.

The north side could be covered with a white 4x8 sheets of plastic or ply wood on the inside , with insulatation between the inner panel and outer sheets of "skin", on the inside of the north side staple silver bubble wrap insulation to maximize light from reflection.

just some thoughts

Psy is that cause of global warming?

I got a green house put back together after a storm and a tree fell on it. Not quite finished but  am hoping my big strong nephew will help me move it after work today.

Its just a little one but enough for me.

I look forward to posting pics of it up and running.

There are many greenhouse plans out there. Hoop houses are very easy. others designs are easy to and your ingenuity can help you build one for little and serve you well.

I hope no plants were hurt in the sideways filming of your greenhouse de-construction. :)

Cinder blocks are good, hell I remember back when I was single I used them for furniture......
