Greenhouse tips
Greenhouse floors need to drain. A few inches of washed stone over landscape fabric keeps roots and weeds down and dries quickly after watering. Avoid stone with a lot of fines, which can turn muddy.

Prep
Clear vegetation, rake the soil level and compact it. Lay fabric overlapped at the seams and set edging before spreading the stone.
Buying the stone
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Crushed stone has angular faces that lock together under a compactor, which is why it holds a pad shape. The scale ticket is the real weight; tons per yard here is a planning figure.
Planning the cost
Stone is usually priced per ton or per cubic yard, and delivery is often a separate charge based on distance. A full truckload can cost less per ton than a partial one, so it can pay to combine projects. Ask whether the quote includes tax, delivery and any small-load fee before you compare yards.
Tools for the job
A flat shovel, a steel rake, a wheelbarrow and a rented plate compactor cover most residential pads. A landscape rake or the back of a rake levels the top layer, and a long straightedge or a level string shows high and low spots before the final pass.
