Can I put an 8 X 10 greenhouse on decking? Can I screw the base onto decking? Am I heading for disaster? I will buy toughened glass and bar capping.
You could but will have to dismantle it a few years down the line when the decking rots. The humid conditions and condensation running down the glass inside a greenhouse will probably accelerate that happening too. Wood preservative is toxic and something you definitely want to avoid using anywhere near a greenhouse, so that's not really an option to prolong the life of the decking.
I would put the effort in now to either remove the decking and build a proper base or put the greenhouse somewhere else.
Thank you - brilliant advice. I will try and find a good gardener to take up the decking and put some paving slabs down. Again - thank you.
That's a good idea, think of the rats under the decking, they may come into your greenhouse in the winter. I have mice in mine.
you can't beat a good base for a greenhouse.
i wouldn't ask a gardener to take up the decking and lay slabs, gardeners can be very expensive. Try someone in the building trade, or even a man friend could do it.
oops! Sexist remark, even a strong friend could do it
tee hee @ " even a man "
I know! I could have deleted, but you what a devil I can be.
