PRO-MIX® HP® AGTIV® REACH™ GROW BAG

High porosity growing medium

Former name: PRO-MIX® HP® MYCORRHIZAE GROW BAG

PRO-MIX® HP® AGTIV® REACH™ is perfect for growers that require a growing medium with good drainage, high air porosity and low water retention. The combination of fibrous Sphagnum peat moss and a high percentage of coarse perlite makes this formulation ideal for growers who require a growing medium product that is adapted to their needs for watering flexibility and crop seasonality. PRO-MIX® HP® AGTIV® REACH™ contains a beneficial endomycorrhizae that improves plant growth.

Frequently Asked Questions

To use PRO-MIX® grow bags, shake the bag to gently unpack the growing medium, tear the removable part of the bag and transplant directly in the bag, avoiding compaction.

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 percentage 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 overwatering, to low light growing conditions or for use in winter months when daylight is shorter.

Using the Saturated Media Extraction test method (SME), PRO-MIX® HP® is formulated in a pH range of 5.2-6.2. Once the product is opened, crops planted and watered, limestone is activated and pH will reach 5.8-6.2 within 7-10 days.

We do not recommend reusing PRO-MIX® HP® or any growing medium. There are many good reasons not to reuse, including changes to chemical and physical properties over time, diminished effect of wetting agent after use and/or transmission of root diseases to newly planted crops.

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).

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.

PRO-MIX® HP® can be used for transplanting seedlings. However, we suggest PRO-MIX® FPX for seed starting and seed germination.

PRO-MIX® HP® is a peat-based growing medium formulated 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.
