What is a Poly Tunnel?
It is a tunnel made of polyethylene. Inside it heats up
when the sun shines down on it (this happens on sunny and cloudy days). The heat warms up the plants and soil inside the poly tunnel and makes it grow faster than it would outside in the ground.
You can make the tunnel warmer or cooler by opening up the flaps or by using equipment you have put inside to addheat or cool air.
