Home-made low cost greenhouse designed to use free untreated pallet wood. Or, how to build a viable, safe, year-round food production system.

The 5 Euro greenhouse...

its organic produce..

Good companions, Courgettes and Tagetes erecta

its tenants..

Vladamir, Diavolo and Co., pretending not to notice that the quail have a big heap of compost to play in. At the end of the courgette season the quail move in to clean up the woodlice from the rotted compost so that we can plant the next lot of vegetables.

and its next lot of produce..

In line with tradition, we planted our garlic on the shortest day and will harvest it (hopefully) on the longest.

These three models of greenhouse were made on the same principles of construction. The most expensive, made from recycled glass windows and pallet wood, will cost more if you purchase the leaded light and wooden posts. Our cost was 50 Euros but I estimate it would cost around 100 Euros if you needed to purchase the above items.

With water shortages, uncertain weather and continuing fallout from Fukushima, you can provide your family with year round vegetables, fruit, herbs and flowers. The 7 Euro Greenhouse (opposite) incorporates a recycled glass window and has purchased polythene on all sides. Its interchangeable panels, in hotter weather allow for the polythene covered gable ends and the door panels to be removed and swapped for wire mesh ones, to allow for ventilation.

The largest greenhouse - which has all its walls made of recycled glass is more robust and remains warmer longer, once heated by the sun. For this reason it can, with the addition of fleece covers, be used for growing more tender vegetables throughout the year. It is however, a more difficult project. Start small - work up!

Anybody with the ability to assemble flat pack furniture can get to grips with this design in its cheapest form.

The greenhouse walls were made using the vertical uprights taken from a set of pallet shelving which originally had served to hold pot plants. They were 80cm wide and 170cm tall. I was able to recuperate some wire fencing from our local dump and cut it to fit these rectangular frames. I have since recuperated several of these shelving systems so they seem to be a standard throw-away pallet item. If however, you can not get hold of them just use your stock of pallet wood to create something similar. I used four of these frames (shown opposite) in all.

Mass Production:

Home-made pallet jig

The first thing I always consider, in a design of this sort is to create a way of getting a uniformity of construction. This is not just for aesthetics but because it makes everything easier when you come to fit the project together! To this end I set up a simple jig - out of pallet wood of course!

To fabricate the 5 identical roof trusses needed for this design, I constructed a jig from two pallets joined together to create a worksurface of roughly 2.40m in length. Wooden blocks were then screwed at key positions so as to act as 'stops' when the truss components were laid onto the pallet.

Something perhaps not so obvious in the Youtube film, is that my design incorporates a vertical piece of wood at the lower end of each truss. This enables each truss to be fitted to the inside face of the greenhouse wall. Once screwed into place, this addition prevents the tendency for the truss to move outwards. I felt that this vertical piece of wood, pushing against the inside face of the greenhouse, would be more secure than just relying on a screw or nail to hold the truss in place.

Once attached to the opposite walls the trusses were joined to each other at the side of the roof apex using pallet wood planks. This way of linking each truss means the whole roof structure becomes stiffer and provides a 'smooth' surface for the polythene roofing at the apex. See photo above.
