PRO-MIX FPX
FPX - plug and germination
Providing an optimized growing environment is fundamental, especially when it comes to plugs and germination, as it will define future productivity levels. PRO-MIX FPX is well adapted for water-sensitive crops by providing low water retention levels and good air porosity for developing seedlings.
Crops
- Vegetable transplants
- Plug & Germination
- Young plant propagation
Benefits
- Easy filling of trays
- Improved drainage and air‑exchange for developing roots
- Dry out faster than peat/ vermiculite blends for easier water management
- Reduced calcitic limestone allows grower to have better control of pH with high water alkalinity
- Reduced fertilizer charge gives grower better control to prevent seedling "stretch"and growth
Certifications
-
VeriFlora® is an agricultural sustainability certification and eco-labeling program recognized as the gold-standard in the floriculture and horticulture industries.

Advice from our specialist
Premier Tech Horticulture offers two products: PRO-MIX FPX, which contains perlite for extra drainage, and PRO-MIX PGX, which contains vermiculite for more water retention. When using these products, remember to start fertilizing after the emergence of the first true leaves. For the best root development, cut back waterings once seedling roots go to the sides of the container. Allow the surface to dry down between waterings, which will encourage the development of an extensive, deep-rooted root system.

How Substrate Structure Influences Water Holding Capacity
Choosing the right substrate not only depends on the physical properties of the substrate, but also on the type of plants to be grown, the growing environment and the availability of the substrate.

Substrate Handling Influences Water Holding Capacity
A mixture of coarse and fine particles can be prejudicial for a substrate because the macropores will be filled by the fine particles, which reduces the air porosity of the growing medium.

Ingredients

SPHAGNUM PEAT MOSS (80-90%)
?
Canadian Sphagnum peat moss is a natural, organic matter that comes from a peat bog. This primary resource is carefully harvested by vacuum harvesters. Peat moss comes in various fibrosity and levels of decomposition. Once carefully graded, peat moss assures that qualities of each grade are optimized for based on grower and uses for a final product reaching high quality requirements.
-
PERLITE
?
Perlite is an alumino-silicate ore of volcanic origin. The raw ore is crushed, graded and screened in various particle sizes. Perlite has a high total-porosity and improves drainage and air porosity.
-
LIMESTONE
?
Used to adjust pH to optimum range. Also a source of Calcium and Magnesium.
-
WETTING AGENT
?
A wetting agent is a substance that reduces the surface tension of water, allowing water to penetrate and uniformly wet growing media.
