DIY Cold Frame


Hey guys!  A couple of weeks have went by since we started our vegetables from seed and now we have these beautiful full plants…only problem is we have nowhere to put them after they are separated.  The plants are to the point now that Kyle and I had to divide them up and plant them into their own containers which is what they will grow in until we plant them in the garden.  Until then they will have to eventually go in a “half way house”.  Somewhere to get acclimated to our Ohio weather.

Here we are separating our tomato plants.

So being proactive Kyle decided to build a small cold frame with some spare lumber and plastic we had laying around.  I’m not going to lie, I didn’t help with this build.  I was tending to the kids…and being lazy.  I did however write down his measurements and all his supplies.


4- 2×4’s

2 1/2 inch screws(we used our Kreg-Jig)

6 mil thickness plastic

Staples to secure the plastic

All of the cuts were made with either a straight cut which you can clearly see or a 22 1/2 degree cut so you will have to adjust your saw accordingly.  Just a reminder for the newbies when you cut a angle you always measure the longest distance ;).

I will break all the cuts down.

2-A’s @ 11″ using two angled cuts

4-B’s @ 18″ using two angled cuts

4-C’s @ 18″ using ONE angle and One straight cut

2-D’s @ 29″ using all straight cuts

5-E’s @ 33″ using all straight cuts

After all pieces have been cut I like to lay it all out.  Next we used our Kreg-Jig to make the pocket holes to fasten them together.  You can see here all of the holes we used.  We fastened them together using 2 1/2″ screws and Tite Bond Glue.

Here is another view of the cold frame.  Don’t mind my photography, I was holding a crazy baby while snapping these!

After you get your frame together, Kyle took a hammer and beat down all the sharp edges so the plastic wouldn’t catch or rip.

Next we measured out the 6 Mil plastic.  We just used what we had on hand, but if your going to buy the plastic I would choose a clear plastic.  I feel like it would let more sunlight through.  Sunlight=Happy Plants!  The plastic needs to measure 7′ by 8 1/2′ for the dimensions of this cold frame.  Using a hand stapler we secured the plastic to the wood.  You can leave a opening if you want, but we didn’t want a lot of air to be blowing so we chose to close it all in.  With this being small we can pick this up and set it over our plants when we need access.  So here it is!  Kyle’s Take on a virtually FREE cold frame.  After this cold snap passes this weekend we will start to acclimate our plants to the cold frame…planting season is coming soon!!
