What is PULSE® Gro-Coat®

An organically compliant seed pellet. PULSE® Gro-Coat® envelopes the seed creating a uniform pill shape and increasing the weight which makes more accurate planter metering and placement of the seed possible. When germination conditions are moderate and not adverse, PULSE® Gro-Coat® is the right choice.


Key Benefits

The industry-leading way to deliver organic pelleting requirements. This seed treatment is a pellet application for most vegetable seed that germinate in average conditions such as California Coastal climates. It is a pelleting process that can be customized for a range of requirements in terms of density and size.

PULSE Gro-Coat Pellets:

  • Are uniform in size
  • Split quickly when exposed to moisture. This is important because when seeds germinate respiration increases dramatically. When seeds respire, they require both moisture and readily available oxygen.

Not Primed

PULSE® Gro-Coat® is not for use on light sensitive lettuce varieties or those lettuces that will be planted and germinated in high heat conditions; those seeds need to be primed.


We have developed different pellet weights and densities to fine-tune plantability and ease of handling. Conscientious growers adjust the weight of their pellets to match their tractor speeds. Faster tractors require heavier pellets for more straighter accurate drops. More accurate drops produce less bouncing in the seed furrow, and that maintains field singulation and uniform plant spacing.

This product is available in several weights for lettuce: High Density (HD) Medium Density (MD) Light Density (LD). The pellet size can remain the same. We can modify the weight to meet the needs of your planters and planting conditions.
