Lambert Professional LM-191 substrate is a slightly less coarse version of their best-selling all-purpose blend, the LM-111. This new mix is blended with a specially selected grade of sphagnum peat moss and coarse perlite. An additional step in the screening process of the peat was done to allow this all-purpose mix to be more widely adaptable, including the utilization in 6-pack, 50 and 72 cavity trays. Available in 3.0, 74 cu. ft. loose filled bags, and 3.8, 55, 120 cu. ft. compressed bales.
