Step 2: Building your cold frame

1. Get yourself an old window frame with glass. Preferably 3-4 feet wide, so you can easily reach the back.
2. Construct a wooden frame that fits your window frame. Make the back of the frame higher than the front. Remember to use non-decomposing wood.
3. Attach the window frame to the wooden frame using heavy duty hinges.
<p>very nice. i had done this a while back..</p><p><a href="http://www.instructables.com/id/Pallet-Greenhouse/" rel="nofollow">http://www.instructables.com/id/Pallet-Greenhouse/<br></a>thank you for sharing.</p>
<p>nice job!</p>
Non Decomposting wood....such as???????<br />
&nbsp;you can use red wood, used in building where it may come in&nbsp;contact&nbsp;with moister. red wood will deteriorate, but long after you are done with this.<br /> you can also use trex, it is a wood alternative used in decks. i think it's plastic or a mixture of plastic and other material, either way it looks like painted wood.
Trex-style products are usually a plastic/wood dust combo. Cedar and Redwood are both rot resistant
You know, turning your sod upside at the bottom of your little plot will add composted material and a bit of nitrogen for your plants. Not to mention preserving worms.
How do you know at what angle the frame should be? That is, what are the considerations for angling the windows at a 0 percent slope vs., say, a 30 percent slope? <br /> <br /> I've read that too great a pitch (slope) causes hot spots that are not conducive to plant growth, while too low a pitch eliminates too much sunlight. In addition, I do wonder why not make a double sided cold frame...kind of a mini green house.<br /> <br /> Any insight would be much appreciated as I have some windows that I'd love to incorporate into a cold frame, but am unsure about the pitch issue.<br />
great idea.&nbsp; I have used bales of straw positioned in a pattern that fits the old wooden storm door I found at the dump. this is not my idea I saw it in some garden forum years ago&nbsp;and &nbsp;it works well&nbsp; and I use the straw for mulch duing the heat of summer around my daylillies. I have&nbsp;a plank that was once a table top placed vertically&nbsp;that I hinge the door to, which is braced by&nbsp;the&nbsp;bales on the line of straw bales&nbsp;and use the old door&nbsp;pull to lift&nbsp;it&nbsp;which gives me acess to the plantings. all of the&nbsp; door then sits&nbsp;on the&nbsp;&nbsp;sides and front bales which provide wonderful insulation. quick and easy.<br /> thanks,<br /> james
<p>You can use redbrick and a little sand mix to line the perimeter of the box setting the box on top of your small wall and use caulk to seal between them both this way you could use just about any type of wood preferably oak is what i would use ..<br /> <br /> Just A Thought</p>
nice project<br/>If you line the inside with polystyrene sheeting it will stay warmer and keep frost out and use white will make it better for light.Reflects it<br/>The biggest problem i have i can never make enough :)<br/><a rel="nofollow" href="http://www.gardenersworld.com/how-to/projects/cold-frame-insulate/">http://www.gardenersworld.com/how-to/projects/cold-frame-insulate/</a> <br/>
Great idea! About how cold can it get outside before you start to worry about this thing's ability to insulate?
