Key Takeaways

Premier Tech’s Open Top Grow Bag is a new system perfectly adapted to the cannabis grower’s needs. It’s a labor-effective solution for an improved workflow and it requires very little clean up, resulting in valuable savings, both in time and money.

Going to a hydro store can be an overwhelming experience when having to choose between a huge variety of products to make plants grow (growing medium, nutrients, beneficial microorganisms, lights, containers, irrigation systems, etc.). Containers, whether one opts for cell containers or gallon pots for transplants, are always a necessary purchase.


A grower’s choice of container varies depending on space, water retention needs, desired root development, material (plastic, fabric) as well as different watering methods. These choices play an important role in the development of plants and their root system.

Pairing the right container with the right growing media plays a crucial role in having a successful grow. The combination of physical, chemical, and biological characteristics helps define the root zone, provides the plant with fiber and structure, and determines the water holding capacity as well as the exchange and air porosity necessary for healthy roots.


Once you have the right combination of container and soil, the real work begins: filling the containers, placing them in the right spot, cleaning, and storing extra growing medium. When reusing containers, add cleaning and sanitizing to the already long list of things to do! Keep in mind that each extra step you take to properly care for your containers will add up in time and labor cost in the end.

All of this is a lot of work! And growers from the cannabis community are always looking for better technologies that will give them an edge in yield, quality, sustainability, and overall results. Therefore, providing the plants with the best growing conditions and improving nutrient intake while reducing the overall labor only makes sense.

The Research

Taking in consideration the growers’ needs for a cleaner environment and to help them save in time and costs, Premier Tech Growers & Consumers started developing a new product: a grow bag system. The end goal was using the technology behind PRO-MIX® HP® growing medium, combining its active ingredients such as Mycorrhizal and/or Biostimulant technology, and delivering it in an easy to use, cleaner format.


Today, Premier Tech introduces a new delivery system for their PRO-MIX® HP®: the all-new PRO-MIX® HP® MYCORRHIZAE™ Open Top Grow Bag.

Advantages for the Cannabis Community

Developing a New Delivery System for PRO-MIXThe Open Top Grow Bag solution was designed with multiple characteristics to ensure ease of use: eight pre-cut drip holes, an easy tear-off opening method that requires no tools, 1-ft3 of loose-fill growing medium, as well as multiple openings for aeration and equal air distribution in the root zone to promote root development. Keeping the interior of the bag lighter than usual containers also contributes to better root development and distribution. This system is perfectly adapted to the cannabis grower’s needs. It’s a labor-effective solution for an improved workflow and it requires very little clean up, resulting in valuable savings, both in time and money.


PRO-MIX® Open Top Grow Bag solution helps growers keep a cleaner growing environment. Key steps to reduce contamination and plant disease such as grow room sanitizing, disinfecting, and sterilizing are simplified thanks to a quicker, cleaner set up with reduced manipulation.

In an ongoing effort to deliver adapted solutions for the industry, Premier Tech develops and uses active ingredients, which add value to a well-balanced growing media. The addition of active ingredients gives growers the return on investment they seek in crops and yields, along with the opportunity to save cost and time, which have always been key for PRO-MIX®.

According to Mitchel Alswiti, CEO, founder, and Master Grower at Purplefarm Genetics, “By using the HP® grow bag, we are saving around 25-50 percent in transplant labor and from a planning and time savings standpoint. As the grow bag is already filled with growing media, it reduces handling, making the transplanting process cleaner, and we get the same consistency as with the HP® + product itself.”

More than a Growing Medium

The formulation inside the bag is a key component of the technology. To increase crop yield and quality, the active ingredient included in the grow bags is carefully chosen for their growth enhancing properties:

Mycorrhizae are the beneficial associations between a mycorrhizal fungus and roots, which boost the plant’s water and nutrient uptake. This increases the plant’s resistance to environmental stresses such as drought, compaction, salinity, low fertility, and transplant shock.

Designed to prevent plant problems and to ensure quality and sustainability to every facility or growing environment in a renewed integrated growing solution, PRO-MIX® HP® MYCORRHIZAE™ Open Top Grow Bag brings:

✔ Less labor
✔ Quicker set-up
✔ Easier handling
✔ Pre-cut drain holes
✔ Easy tear-off
✔ No need for cleaning or sterilization
✔ Decreased risk of handling contamination
✔ No containers required
✔ Quick post-harvest room turnover

And we’re not done! In the near future, PRO-MIX® plans to introduce new product sizes of this delivery system, all the while focusing on what the growers want and need. Stay tuned, we’re just getting started!
