Best $18 I've ever spent

I wanted something simplier than a standard door for our hoop - HomeDepot has heavy duty double sided zippers for construction barriers which is also good in very cold temps and outdoor application. Voila - greenhouse door. $18 per set and less then 30 minutes to install.

30 minutes to install?

Maybe I'm thinking of a different product, but when I worked for a water mitigation company, we had to hang lots of plastic barriers. We used the zippers for the plastic, and after I learned how, it only took a minute at the most.

The kind we used had a permanent adhesive to grab the plastic. So you take it out of the box, figure out which way is up, pull off a little of the nonstick backing, and attach one end of the zipper to the sheet. Then you work to the other end, pulling of the backing as you go. When you're done, you unzip it and cut the plastic between.

That's the key, cut the plastic last. I wish I could say I figured that out on my own. When the sheet is all solid, everything stays where it belongs and the zipper goes right on. Unzip and cut the opening, badabing. Took way longer to write this than to perform it!

hahaha Mike - the 30 minutes included installing the plastic enclosing the ends as well as the zippers (and that was for both ends). I may be really short, but not really slow
bada-Bing indeed!

Well that makes a whole lot more sense.


Nice job on the greenhouse, and nice job connecting the dots between a easy-to-use product and a great off-label application for it.

Keep us posted how these hold up outdoors!

let us know how it stands up to wind. It really is an easy solution--and cheap, too.

I may use that to make temporary airlocks on a couple doorways to keep out the cold this winter...

With lots of rain, huge temp swings, the adhesive has lost it's punch. Easy fix aka Gorilla tape, 15 minutes and done.

We're in 7A/B and don't heat our greenhouse. The sides are filled with pebbles then rocks which suffices even with normal night temps in the 20s and occasionally in the teens and rare single digits.

One the best things we've done is to capture the water runoff and direct it into the house. A channel was dug on 1 of the long sides, sloping slighting to several inlets into the house and then to another that leads down the center row and into the channels of the keyhole structure of the beds. It's been a fairly rainy fall/winter and in the last 3 months, we've only watered 3 times and it was just to hit the center portion of the keyholes. I snapped this pic a couple of days ago when I did have to water since it's been sunny and high 50s for the past couple of days. At the far end of the center channel is an "escape" with a wooden slat that can be removed to evacuate too much water when we get our 4" of spring rain storms.

I'm wondering what all is growing in there? I see lettuces and spinach.....looks wonderful and I am very envious

Hey Judith,
A bunch of different lettuces, arugula, spinach, tatsoi, mizuna, cilantro (a far better winter crop here) carrots (only a few left though) radishes, beets. I also let some of the early fall crop go, to give us spring seeds. It's been so grey here this winter with bitter winds, that it does my soul good just to go stand in the mist.
