Greenhouse flooring project.

[BrassavolaStars]

Hello all,

As a summer project, I would like to install some kind of floor for my greenhouse. Currently, the floor is just top soil. I believe I would like to use pavers stones (but am still open to other choices) as I find brick pavers very aesthetically pleasing. Is this a bad choice of flooring? Is there something better I’m overlooking?

Either way, I have no idea how to install them and would like to know how if they end up being the final choice.

Allegedly, they get placed on top of sand. Many sands apparently come in two forms to be used in conjunction: a coarser sand to be used as a base and a finer sand to be used as a second layer.

Do I actually need both or is one optional? Do I need additional pebbles at the base to make sure it drains well? I am completely unsure and would love advice.
