Instant pre-calculated material estimates for common US residential project sizes before compaction buffer:

Typical US Project	Area	Depth	Volume	Weight	Store Bags
Greenhouse Bench System (3 benches: 3 ft × 15 ft × 6")	135 sq ft bench	6 inches	2.50 cu yd (67.5 cu ft)	1,500 lbs	23 bags (3 cu ft bales)

Cubic Yards = (Bench Length × Bench Width × (Soil Depth ÷ 12)) ÷ 27

Calculates bulk potting soil volume or pro-grower bales for commercial greenhouse benches and propagation tables.

Greenhouse starting mixes must be sterile and light-textured (peat moss, vermiculite, and perlite) to prevent seedling damping-off disease.

Always exactly 27 cubic feet per cubic yard.
