Our Native Seed is sold by “Pure Live Seed” Weight
All our Native Seed is sold on Pure Live Seed weight. This is really important to you! It means that a Government certified testing lab has tested our seed and that we only charge you for the seed you receive that is guaranteed to be viable. It means you do not pay for empty seeds, dead seeds, leaves, stems, dirt, weed seeds, or any other contaminants that may be in the seed from others who charge for their seed on Bulk weight. From Roundstone Native Seed you only pay for viable seed and this can mean a huge difference in your cost.
How is Pure Live Seed (PLS) Calculated?
A certified test determines the purity % and germination % of each lot of seed. Purity % = the % of actual seed in the lot Germination % = the % of actual seed that can germinate. PLS % = Purity % X Germination %
Example: Where Purity is 90%, which means 90% of the weight being purchased is actual seed, and where Germination is 70%, which means 70% of the actual seed are guaranteed to be viable. In this Example PLS = .90 X .70 = 63 percent
How Does Buying by Bulk Weight Affect Your Cost?
A Low Bulk Weight Price can be very misleading. Example: Pure Live Seed Price at $36.00 per pound on a species with 100,000 seeds per pound and 63% PLS VS Bulk Weight price of $29.00 per pound on the same species with 100,000 seeds per pound Bulk.
PLS cost = $36.00 for 100,000 viable seeds
Bulk cost = $46.03 for 100,000 viable seeds
While initially appearing to be 24% cheaper in this example, purchasing by Bulk Weight is actually 28% higher, and depending on the PLS percentage, it could be much, much higher.
NOTE: The seeding rates for USDA Farm Bill Programs using native seed are in PLS pounds and the use of Bulk Weight to fulfill the seeding rates can be a cause for contract compliance failure!
