Germination
ProEarth Organic Seeding Mix for conventional trays and seed cells.
Stage-specific production media
Farms & Propagation
Plan germination, soil-blocking and potting-up as a production sequence, then connect each stage to quantity, packaging and repeat supply.
Production sequence
Germination → Blocking → Potting Up
Each stage has a different physical job and may require a different commercial product.
Blocking
ProEarth Organic Blocking Soil Mix for cohesive block production.
Potting Up
Move established plants into a medium suited to the next container and production duration.
Commercial program
Quantity, repeatability and packaging matter.
A good product recommendation still needs a workable supply plan.
Production quantities
Estimate bags, pallets or other available formats for each stage and planting window.
Learn more →Repeatability
Record the approved product, stage, tray or block system and reorder schedule.
Learn more →Samples
Trial candidate media against a defined production objective before broad changeover.
Learn more →Custom farm media
Review standard products first, then define a genuine unmet requirement if needed.

Commercial propagation and potting-up products.
Keep the current soil-blocking product tied to blocks and the seeding product tied to conventional seed-cell propagation.

Farms & Propagation FAQs
Use the project details—not the broad label alone—to choose the next step.
Should all farm propagation use Seeding Mix?
No. Conventional germination, soil blocks and potting-up are separate jobs.
Which product is for blocks?
ProEarth Organic Blocking Soil Mix is designed for soil-block production.
What commercial information should I send?
Send stage, tray or block system, volume, format, planting schedule, delivery location and repeat-order expectations.
Can Specialty Soils make a custom farm medium?
Possibly, after existing products are evaluated and a real unmet performance requirement is defined.
Stage-by-stage review
Propagation media changes with the production job.
Do not route every propagation project to one seeding product.
Seed cells & trays
Prioritize uniform contact, moisture and early root development for conventional germination.
Soil blocks
Use a blocking medium when cohesive block performance is part of the system.
Transplant stage
Move established plants into media appropriate for the next container and management plan.
Longer production
Review duration, irrigation, fertility and container stability after propagation.
Repeat supply
Record the approved stage, product, format, volume and timing.
