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.

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.
Getting it delivered
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. Ask your supplier for their own tons-per-yard number, since stone source and moisture change it.
Measuring the area
Use a long tape and measure each side twice. If the ground slopes, measure depth at the high and low ends and average them. Irregular outlines can be broken into simple rectangles, triangles and circles; add the pieces for the total square footage before converting to tons.
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.
