Would putting a fleece over the veg in my greenhouse for the whole week do them any harm? Weather here has a few frost's coming while I am away. Plenty growing in there turnips carrots Paris cos lettuce all doing well.
Thanks

Fleece is really at its best when used to protect outdoor crops from ground frosts, which it does by deflecting the cold descending air away from the plants underneath.

It really needs to be in much thicker layers to be an effective insulator in other circumstances, which is not really practical in your greenhouse situation (apart from potentially flattening the plants, you would probably lose more by the fleece stopping any sun from warming the soil than you would gain from the insulating effect.)

To late! I am not worried about flattening plants as hasn't done up to now. It will be on for week. I was just putting it on at night. Although after week it may have flattened them. I will report back. I should have made sure it wasn't resting on the plants. I was as usual in a rush. Thanks
