Any ideas on the best type of flooring for a permanent greenhouse? I'm thinking a layer of landscape fabric topped with sand and then cement stepping stones......better ideas appreciated.....

Welcome!

My first greenhouse had that floor. I loved it. I used rectangular paving brick and layed it in an interesting pattern. There's no reason not to have a pretty floor and the drainage was great.

Clean pea gravel is the best, next to concrete for a greenhouse floor. There will be a lot of water hitting the floor everyday while in use. Plus you will need to bleach the floor from time to time. If you put sand under the pea grave for extra drainage its a plus. Good luck and happy gardening.

I used bricks, the decorative ones that came in several shades.
I used 2 X 6 treated lumber on edge for my controlling edging. Then laid 3-4" of builders sand leveled and pounded as a sub-floor. Then laid the bricks inside in a herring bone pattern. Left over sand was repeatedly swept over the bricks filling in the tiny spaces and cracks really locking the bricks in place!
Underneath my benches, I used wood mulch. When I watered my plants, the wood chips or mulch provided wonderful drainage! The bricks were held snuggly in place by the wood edging and lasted perfectly for 30+ years.

Pea gravel doesn't work that well because it never packs. Wall to wall bricks worked for 30 years (and probably are still). I grew orchids and ferns - my greenhouse was a very wet place.

I never bleached the floor (why would you?) but periodically washed it. How would you bleach pea gravel?

Mine is bricks, with sand underneath. Drains well and easy to sweep up debris.
