Greenhouse tips
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
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. Gravel is a broad label, so confirm whether the yard means crushed or rounded stone and whether it carries fines. Round up by about 10 percent for compaction and uneven ground.
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.
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.
