Crop and stage
Propagation, potting-up, finishing and holding do not have the same needs.

Greenhouses
There is no universal best greenhouse mix. The correct medium fits the crop, container, irrigation, fertility program and production duration together.
System-first selection
Begin with irrigation, fertility and container duration.
Two growers with the same crop can need different physical behavior because their containers and management systems differ.
Container
Include size, height, automation and production duration.
Irrigation
Describe frequency, volume, delivery method and dry-down expectations.
Fertility
Describe the feeding program the medium must support.
Media behavior
Balanced, high-air and specialist paths.
The crop name alone does not assign the product.
Balanced production
Growers Professional is a practical general greenhouse/container starting point.
Learn more →High-air systems
A hanging basket does not automatically require ProEarth #2; the actual high-air and free-draining requirement must fit.
Learn more →Controlled flowering
A flowering crop does not automatically require ProEarth #4; choose it only where its production role fits.
Learn more →Intensive programs
M&R is for experienced growers using high-aeration, frequent-feed production—not general homeowner media.
Learn more →Vigorous flowering
Wizard’s can fit appropriate vigorous flowering programs without assuming the intensive M&R management style.
Learn more →Custom blend
Use a custom path only when current products do not satisfy a defined system requirement.

Balanced and specialist greenhouse media.
Keep each specialist mix connected to the physical behavior and management system it was intended to support.

Greenhouses FAQs
Use the project details—not the broad label alone—to choose the next step.
Is ProEarth #2 best for every hanging basket?
No. A basket shape does not prove the crop and irrigation system require a high-air, free-draining medium.
Should every flowering crop use ProEarth #4?
No. Flowering alone is not the decision. Production system, crop duration, irrigation and fertility still control the fit.
Who is M&R for?
M&R is a specialist high-aeration medium for experienced growers using intensive, frequent-feed management.
Can I request a trial sample?
Yes. Include the objective, crop, container, current medium, irrigation, fertility and evaluation schedule.
Greenhouse system review
Controlled environment does not make every system the same.
Define the container and management system before choosing a balanced, high-air or specialist product.
Container geometry
Size and height change the water profile and the physical behavior required.
Irrigation frequency
Describe delivery method, timing, dry-down and automation.
Fertility program
Connect the medium decision to the actual feeding approach.
Crop duration
Separate propagation, short finishing cycles and longer production.
Trial
Compare candidate media under representative greenhouse management before a full changeover.
Describe the greenhouse system—not only the crop.
Send container, irrigation, fertility, duration, current media and the behavior you want to change.
