Advice from our specialist
How do I use PRO-MIX HP?
To use PRO-MIX HP, open the package, remove some PRO-MIX product and place into a large tub or container. Lightly break up any clumps so that the PRO-MIX is light and airy. Most growers prefer to add a small amount of water prior to filling containers. If you add water, add enough so that the PRO-MIX product is slightly moist to touch. Do not saturate.
Fill flats, containers and/or pots, without compacting the PRO-MIX in the container. Plant your seedlings, young plants, etc., then water in containers.
What's the difference between PRO-MIX BX and HP?
PRO-MIX BX is a general purpose growing medium, compared to PRO-MIX HP which is a High Porosity growing medium. These products are the same in pH and chemical properties. The difference is that PRO-MIX HP contains a higher percent of perlite than PRO-MIX BX. Perlite is a porous aggregate that does not absorb water.
When incorporated into growing media, perlite provides air porosity and reduces water retention. Since PRO-MIX HP contains a higher percentage of perlite than PRO-MIX BX, HP holds less water and is better suited for crops that are sensitive to over watering, to low light growing conditions or for use in winter months when daylight is shorter.
What is the pH of PRO-MIX HP?
Using the Saturated Media Extraction test method (SME), PRO-MIX HP is formulated in a pH range of 5.2-6.2. Once product is opened, crops planted and watered, limestone is activated and pH will reach 5.8-6.2 within 7-10 days.
Can you reuse PRO-MIX HP?
We do not recommend to re-use PRO-MIX HP or any growing medium. There are many good reasons to not recycle, among these include changes to chemical and physical properties over time when in use, diminished effect of wetting agent after use and/or transmission of root diseases to newly planted crops.
When to water PRO-MIX HP?
When irrigating, add water to PRO-MIX HP until it is saturated from top to bottom of the container. You will know you have accomplished this when water runs out of the drainage holes at the bottom of the container. Over time, allow the growing medium to dry-out without applying additional water.
You will know when to apply water again when the surface of the growing medium turns color from a dark brown/black (wet) to a light brown/tan color (dry enough to rewater).
Does PRO-MIX HP have nutrients?
Yes, PRO-MIX contains a starter fertilizer to help plants acclimate to a new rooting environment. We strongly recommended to initiate a fertilizer program within 7-10 days after planting. The fertilizer program you select should take into consideration water quality, crop type and the stage of plant growth.
Is PRO-MIX HP good for seedlings?
PRO-MIX HP can be used for transplanting seedlings. However, we suggest PRO-MIX FPX BIO-FUNGICIDE for seed starting and seed germination.
Is PRO-MIX HP soilless?
PRO-MIX HP is a peat-based growing medium formualted with a high percentage of perlite. PRO-MIX HP and all PRO-MIX growing media products are 'soilless', meaning that they do not contain any mineral soil.

SPHAGNUM PEAT MOSS (65-75%)
?
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.
-
BIOSTIMULANT
?
Biostimulant is a naturally occurring strain of bacteria called Bacillus pumilus (GHA180). This bacterium combats harmful organisms to reduce the onset of root diseases and enhances plant growth.

MYCORRHIZAE - PTB297 TECHNOLOGY
?
Mycorrhizae - PTB297 Technology is a Biological Growth Enhancer that increases the yield of flower, fruit and vegetable plants by extending the root system to acquire the most of available nutrients in the soil. Mycorrhizae also improve resistance to root diseases and stresses.
