A micro-tunnel is a structure that provides temporary protection for a crop. Since some seasons it is difficult to grow with a micro tunnel, you can do this while protecting your plants from the elements.
How to make a micro tunnel.
The materials to be used.
The materials you will need for this project are:
- First, you should have several pieces of polyurethane tubing that are 20 cm each.
- You will also need 2 foot irons to drive in the ground.
- A hammer for driving irons and pipes.
- A strong rope, in fact, is better if it is plasticized.
- Strong plastic at least 2 meters wide and 2 meters longer than the entire tunnel.
- ½ PVC pipes by 2.40 meters long.
- How to make the terrace.
As for the measurements, the width must be 1.20 m. You will define the length according to your need and the available space.
To begin with, put a rope on the ground on the sides of the patio, you need to lay it on both sides. So make sure he is four feet apart, face to face.
- How to place the tubes.
Place the first tube 20 cm from where the rope that separates the bed begins. Nail it into the ground using the stick, you need to leave 1.5cm so that it does not fill with soil.
Drive the next tube 80cm from the first and the rest will be nailed 1.2cm from the second tube you placed. Therefore, You need to nail the pipes to both sides of the bed at the same distance.
Also make sure to nail them one in front of the other so that the tube that will make the tunnel arch can fit.
Then insert the PVC tube on one side of the tube you nailed to the ground and take the other end to insert it into the front tube. It will form an arch.
- Place the central cord.
Once you have placed PVC pipes in all the holes forming a kind of tunnel, it’s time to put the rope down.
First you need to measure to find the center of the structure. So there you have to nail a bent iron as a kind of hook. Tie the rope to the iron and nail to secure.
The second step is lift the string in the center of the arc by making two turns of tension. You should also pass it through the center of each arch, stretching to the end.
After finishing, tightening each bow, at the end he nails another iron and knots the rest of the string, tightening it without the bows giving way.
- Place the plastic.
After placing the central string, you must place the plastic on the frame. In addition to centering it so that it covers the entire arch, you will leave a yard on each side everywhere.
Then grab that excess from the start side, squeezing it and nailing an iron into the floor, leaving room to pass the excess plastic, while you tighten it with a knot. Finally nail the iron to secure the plastic.
- Lay the strings.
First pass the string over each bow. Nail an iron on either side of where the arc begins. The second step is tie the rope tightening a little.
Therefore, you need to do this in each arch, at the end squeeze the excess plastic as you did at the beginning.
Now you can open the plastic on one side and start planting.
