I bought a cheap grow house with 4 shelves for growing herbs but the wind has knocked it about and it is starting to lean to one side a bit more than it should.
I plan to build a wooden frame, to remount the shelves on and use twinwall polycarbonate for the panels, instead of the plastic that was over the grow-house frame.
The final unit will be 1.8m high and 40cm by 60cm shelf size. I was wondering what thickness twinwall polycarbonate to use for the panels, the local DIY shop only had 1 thickness but when checking online there is quite a variety: 4mm, 6mm, 10mm, 16mm, 25mm, 32mm and 35mm.
I will likely use the same material to build some cold frames later on.
