Stone for a greenhouse
A stone floor drains spilled water, holds some heat and is easy to rake clean. Many growers use about 3 inches of pea gravel or washed stone over fabric, with paver or concrete stepping paths if they roll carts.

Before the stone goes in
Clear vegetation, rake the soil level and compact it. Lay fabric overlapped at the seams and set edging before spreading the stone.
Ordering and delivery
If you haul it yourself, a typical half-ton pickup should carry only about half a cubic yard of stone, well under what the bed looks like it can hold. Pea gravel is small and rounded, comfortable underfoot, and needs edging because it rolls. The scale ticket is the real weight; tons per yard here is a planning figure.
Tools for the job
For anything bigger than a small path, rent a plate compactor; hand tampers cannot match it. A wheelbarrow, shovels, a hard rake and stakes with string are the rest of the kit. Wet the stone lightly before compacting so it binds.
Common mistakes
People often forget that compaction reduces volume, so they come up short. Others order clean, round stone where a packable crushed stone with fines would have stayed put. Finally, dumping the whole load in one pile far from the work area adds hours of wheelbarrow trips.
