FAQ

AGTIV REACH®, thanks to Mycorrhizae, promotes plant growth, supports root development and enhances water and nutrient uptake. Additionally, it has qualities that reduce transplant shock and strengthen resilience against environmental challenges such as drought and soil compaction.

AGTIV AMPLIFY®, thanks to Bacillus and Mycorrhizae, promotes an amplified root system and better absorption of nutrients and water. It fosters faster germination, increases resistance to transplant shock, and optimizes growth rate and uniformity.

Only available in Canada.

Typical ppm for PRO-MIX® HP® is 1300-1600 ppms straight from the package. The product has a low-level preplant fertilizer charge and two sources of limestone, which contribute to overall EC and ppms. The limestone and some of the fertilizers are in a granular form, which do not completely dissolve and will remain in the product for several weeks. After several leaching with RO water, it is expected to have residual EC and ppms. The remaining 800 ppm is likely from the limestones (contributing Calcium and Magnesium), Sulphur, and a low level of Phosphorus from two of the fertilizer components, and ppms from the micronutrient fertilizer (low levels). There may also be a small amount of nitrogen bound to the organic component (peat moss), contributing 7-10 ppm of NH4. This is all normal.

You won't need to add anything to PRO-MIX® HP® to start your growth. It comes with a wetting agent to help the medium moisten easily. It is also loaded with calcitic and dolomitic limestone to help balance the pH of the media, and a starter load of fertilizer that will last for 1-2 waterings. You will need to begin a fertilization program based on your water quality and the plant's nutritional needs 7-10 days after transplanting.

There is an initial NPK starter charge that helps reduce transplant shock and boost young plants into healthy vegetative growth. This nutrient charge is usually depleted at about 10-12 days after planting so make sure to feed accordingly after this time to keep plants healthy and growing.

The bags are designed to have the correct porosity and ingredients to promote healthy growth throughout the cycle and to hold and release nutrients as the plants need them. Most growers use liquid feed fertigation to supply the necessary nutrients to plants for the substrate to absorb and hold. However, some growers do like to top dress the bags with granular cal mag or other ingredients to reduce the strain on drip emitters that can become clogged over time, and this is perfectly acceptable.

No, PRO-MIX® CX is OMRI listed/approved for organic growing, so you must add cal-mag and nutrients soon after expansion to ensure no nutrient deficiencies occur. This gives the grower more control over inputs and timing for early plantings to be consistent and controlled, while also ensuring the substrate is approved for use in organic production.

Yes! Both bags contain the same coco material, so the hydration process is the same. However, growers should keep in mind that when using PRO-MIX® CX in plant-based packaging, the bag must be fully opened and remain open during watering. Since there are no drainage holes at the bottom, the coco may take a little more time to fully absorb water and expand when watering from the bottom.

The PRO-MIX® CX plant-based packaging features very small apertures that facilitate the exchange of both water and air, in contrast to the plastic bags. We have measured increased exchange of water and air and effective root colonization within the plant-based bags, providing additional space for root development, creating a preferential environment for air and water to exchange.

Extensive testing has shown no visual or measurable degradation in:

- Growth rooms over 12+ weeks (including commercial trials)
- Greenhouse environments over 6+ months

You can grow with confidence; the bag holds up throughout the entire cycle.

~30% for a strong generative approach
~15–20% for a standard approach

Note: The plant-based packaging may cause your plant/media system to dry back slightly faster due to increased drainage and aeration, so monitor closely.

Yes, since the coir product inside is the same, hydration and drainage performance are maintained. The main difference is that the plant-based packaging will dry a little more easily because of the additional space available for the root to grow.

Eco-One® is a brand of organic additives which enhance the biodegradation of plastic products through a series of chemical and biological processes in a biologically active landfill. It allows the plastic to be consumed (as a food energy source) by the microbes.

The quality of the PRO-MIX® won't be affected if you stock products not used in your garage for the winter. If you have a PRO-MIX® open bale, just make sure to re-cover and tape it to prevent anything from getting inside the bale

PRO-MIX® BX is our general purpose growing media, whereas PRO-MIX® HP® is our high porosity media. The main difference between the two is the volume percentage of perlite in the media. PRO-MIX® HP® contains about twice the amount of perlite compared to PRO-MIX® BX. As a result, PRO-MIX® HP® will be harder to overwater and will dry out faster than PRO-MIX® BX, which is useful for crops that do not tolerate as much water in their root zone or in regions that do not receive much sunlight and where pots dry slower.

Our PRO-MIX® products are designed to be used as is, so you don't have to add compost. Doing so may introduce more nutrients and help keep the pH of the growing medium a little more stable, which are good, but compost often plugs up air pores in the growing medium. The result is reduced oxygen access through the plant's roots, which puts the plants under more stress. As a result, growth is often slower and root diseases can often increase.

PRO-MIX® HP® contains 25-35% perlite.

PRO-MIX® HP® has synthetic humidifying agents and synthetic starter fertilizer, making it non-organic compliant. Also, the best way to identify if one of our products is approved for organic usage or not is to look for the "OMRI" logo on the bag. If the product bag has this logo, it means the product is certified for organic use. If not, it means that the product is not intended for organic use.

PRO-MIX® HP® is ready to use. It does not need to be soaked in water before use, but you can mix a little water into the product when you unpack it (2-3 gallons of water per 3.8 cu. ft. bale). You can then fill pots, plant, and then water the containers.

The pH of the water has no influence on the pH of the growing medium. What does change your growing medium's pH are the bicarbonates in the water. Basically, the fertilizer must be matched to the water and the plant, and you will have more success growing the crop than if you try to set the pH of the water to a specific value and hope that the pH of the growing medium stays within the normal range of 5.7-6.2 when growing in peat-based growing media.

The best way to water any PRO-MIX® product is to water until it is saturated from top to bottom of the container. You will know you have accomplished this when water runs out the bottom of the drainage holes of the container. Then allow the growing medium to dry out without applying additional water. You know you are close to rewatering the product when the surface of the growing medium turns from a dark brown to black (meaning the  PRO-MIX® HP® is wet) to light brown / tan color (meaning it is dry enough to rewater).

When transplanting a new plant into a growing medium, the medium must be watered thoroughly so that the medium can settle around the plant's roots. Otherwise, there will be large air pockets around the roots, and the growing medium may be too dry to allow the roots to develop from the existing root ball. Therefore, enough water should be added during the first watering to keep the area around the root ball moist. In general, this means watering from the top and continuing to water until the water comes out of the drainage holes at the bottom of the container. With each successive watering, you can apply less volume, but if you squeeze a handful of the mixture and only one drop of water comes out, the PRO-MIX® may require more water application.

Make sure that during the initial hydration of the PRO-MIX®CX, it is fully expanded and saturated before planting. Use your hands to feel around bags to make sure there are no voids or pockets that have formed; massage bags to eliminate any voids to ensure active root venturing. Don’t overdry the bags during crop steering to avoid making the coir hydrophobic and resistant to saturation. Going past 20% dry back is not recommended.
