New lean to greenhouse - stuff on the floor or not?

[takeabrolly]

My new 6x2 lean to will be going up soon and I was wondering, should I put stuff on the floor? Its going on a patio so it'll be on a hard surface but do I need to put pea gravel or bark chippings down? Does it matter?

I wouldn’t, it will have a sound base and much easier to keep clean. Gravel is not nice to walk on, and tends to migrate outside.

No.. I would leave the floor as it is. It’s easier to clean.. not sure why you would want to put anything else down.

Thank you both. Someone told me I should do that because in the summer it can lower the temp if you dampen it and in the winter gives some protection from cold. I had thought treading the gravel out would be a PITA so I'll leave it bare

You can still dampen the flags. And the flags are an excellent heat storage.
