View ProductTwo buying paths
Finished media and formulation components serve different jobs.
Choose a complete medium for direct planting or a component only when a verified recipe calls for it.
Finished growing media
Choose an appropriate complete medium for the crop, container, exposure and watering routine. Ordinary garden soil is not generic potting media.
Formulation components
Perlite, pumice and other components belong inside deliberate recipes; none is a complete growing medium by itself.
Selection factors
Choose by root-zone behavior.
Fine propagation, balanced general production, durable outdoor nursery structure and specialist high-air programs are different jobs.
Germination & plugs
Fine, uniform media for seed-to-medium contact and young-root development.
Learn more →Soil blocks
A cohesive blocking medium with different handling and dry-down behavior from tray seeding.
Learn more →Long-duration containers
Outdoor and perennial production need structure that fits container duration and management.
Learn more →High-air programs
ProEarth #2, ProEarth #4, M&R and Wizard’s keep their distinct specialist roles.
Learn more →Custom media
Review standard products first; formulate only when the production system has a genuine unmet requirement.
Learn more →Pumice & components
Components can change physical behavior, but pumice is not a complete growing medium.
Learn more →Specialty Soils experience
A product name is only the beginning.
Specialty Soils selects professional media by the production system and keeps specialist products in the situations where they belong.
Made by Specialty SoilsGrowing media is part of the company’s core manufacturing work
Stage mattersGermination, blocking and potting-up are separate decisions
Management mattersIrrigation and fertility can change which medium fits
M&R stays specialistHigh-aeration, frequent-feed production—not general homeowner media

Potting & Grower Media FAQs
Use the project details—not the broad label alone—to choose the next step.
Can I use ordinary garden soil in a pot?
Do not treat garden soil as generic container media. Containers need a medium suited to their drainage, air space, crop and watering conditions.
Is the most free-draining mix always best?
No. Maximum drainage is not the goal. The useful balance depends on crop, container, irrigation and production duration.
Which mix is for soil blocks?
ProEarth Organic Blocking Soil Mix is the current soil-blocking product. Seeding Mix serves conventional seed-cell and tray propagation.
When should I request a custom mix?
When a standard product does not adequately fit a real production requirement and a trial-and-review process is justified.
Need help narrowing professional media?
Share the crop, container, irrigation, fertility program, production duration and desired behavior.
Compare growing media by system
This category compares media families; the application decides the selection.
Home containers, seed trays, soil blocks, nurseries and greenhouses have distinct selection paths. Do not reduce professional media to general potting soil or send ordinary garden soil into containers by default.
