Simple Plastic Tunnel Cold Frame or Row Cover

This plastic tunnel is being used inside of the greenhouse to protect tender plants against a late hard freeze - very effectively I might add.

A simple plastic tunnel like this can serve as a cold frame to grow salad greens  all winter long, to grow out tomatoes and other tender plants, to extend the season for an early Spring start or a late Fall harvest, or even as a screen house to keep birds off of your strawberries or vine borer moths off of your squashes.  You can also use one of these to dry out water logged beds and warm up the soil so that you can begin planting  in early Spring. These devices are so useful, cheap, easy, and quick to build that everyone should have at least one – it’s almost as good as having your own polytunnel greenhouse. » Read more: Simple Plastic Tunnel Cold Frame or Row Cover

Building Greenhouse Doors

<< Building the $50 Greenhouse

Welcome back Stumbleupon Gardeners!

If this looks like too much work – I did a much simpler door on the other end.

This weekend I finally got time to start on the doors for my 50 dollar greenhouse.  The design that I came up with is light, strong, simple, and can be built easily and quickly using only a circular saw and a hand drill.  I must admit that I did use a table saw to rip out the stock, and put it through a planer to accurately dimension it, but this was only a convenience, and isn’t at all necessary for a good result.  This polytunnel door design can be built on a set of sawhorses out in the driveway, but it will be a lot easier if you get someone to help you hold things while you saw, drill and fasten parts together. » Read more: Building Greenhouse Doors

How to build My 50 Dollar Greenhouse

October 27th, 2008
  • First off – you really can build this thing very cheaply, but to do so you have to recycle, freecycle, and scrounge.  If you just go out and buy new everything it will probably cost over $200 – still not bad all in all.

Construction Steps

Hind Sight – What I would do differently

The planning is over and construction on my hoop house greenhouse has begun.  I’ve rounded up all of the materials and it looks like I’m going to end up with about $50 in a 165 square ft. green house. Granted I already had most of the materials because I’m an incorrigible pack rat, but even if I had bought everything new just for this polytunnel It would still only come to about $120 $150 – less than a dollar per square ft.  Due to the fact that we are in the midst of a global economic meltdown, and the future is a bit uncertain keeping the cost of this project as low as possible is an important consideration. » Read more: How to build My 50 Dollar Greenhouse
