Hi i have aquired a large sheet of light blue poly almost clear but no  :roll: .  

My question is can i use this for a polytunnel or not i would imagine its not the fact the sun get through, like a green house, but heats up the space inside :?  or am i wrong?

You do need light to get good results otherwise plants can grow a bit leggy.

hi pete it almost translucent but blue not clear.  the clear ones on our site aren't clear anymore (Dirty)  :roll: but get results

I've never used a poly tunnel before, if you've no other option try it but keep an eye on things. It's a shame to get half way through the growing season only to find things aren't working out quite right, you lose a whole season.

It's the sun light that plants need to photosynthesise, the tint may slow this down depending in the spectrum of colour needed for photosynthesis.

Some plastic goes brittle in the sun but if you don't spend too much money it might be worth a go.

you have the plastic and I have the polytunnel hoops lol.  I am hoping to have a go a putting a tunnel on my plot sometime in the future.  I see we live in the same county too!

[durham_lass]
