Ready-to-Use Grow Bags for Cannabis
Our ready-to-use grow bags simplify installation and reduce labor during setup. Pre-filled and ready for planting, they eliminate the need for filling pots, handling loose media, allowing teams to focus directly on cultivation.
Each PRO-MIX® ready-to-use grow bag is designed with practical features to support efficient production, including pre-cut drainage holes to help manage irrigation and breathable materials that promote strong root development.
Available with peat-based and coir growing media, with options that include integrated AGTIV® biologicals, our ready-to-use grow bags are built to align with different cultivation systems and irrigation strategies.
At Premier Tech, the company behind PRO-MIX® and AGTIV®, we develop grow bag solutions designed to simplify cannabis production in professional growing environments. Backed by decades of growing media expertise, we work alongside growers and industry partners to continuously refine our designs based on real-world production feedback and evolving cultivation practices.
Making daily operations easier
Every feature is developed with efficiency in mind. From tear-off openings that eliminate the need for utility knives to pre-cut drainage and dripper holes that simplify setup, PRO-MIX® grow bags are designed to save time and reduce handling throughout the crop cycle.
Designed for root-zone performance
Our grow bags are paired with proven PRO-MIX® substrates developed to support stable root-zone conditions. Whether using peat-based or coco-based solutions, features such as optimized drainage, breathable materials, and high air porosity help maintain the balance of air and water needed for healthy root development.
Developed through real production experience
We continue to evolve our grow bag offering through collaboration with growers who use our products every day. Their feedback, combined with our expertise in growing media and root-zone management, helps shape practical improvements focused on usability, consistency, and performance in commercial production settings.
Innovating with plant-based packaging
For growers using PRO-MIX® CX, a plant-based packaging option is available on select sizes. Designed as an alternative to traditional plastic packaging, the material features micro-openings that facilitate water and air exchange, helping support root-zone aeration while delivering the same proven coir performance. This innovation reflects our commitment to developing practical solutions that respond to the evolving needs of commercial growers.

"Grow bags make transplanting a walk in the park. We just drop those bags on our tables, rip off the top, and place our plants in them. On top of that, we've noticed that growing in PRO-MIX® adds a bit more flavor to our genetics."

Find answers to frequently asked questions here.
Will hydration and drainage properties remain the same for both Eco-One® plastics and plant-based packaging options?
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.
What is the recommended maximum dryback % during mid-flower crop steering?
~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.
Will the PRO-MIX® CX plant-based packaging break down during the grow cycle?
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.
What is the airflow like in the PRO-MIX® CX plant-based packaging, and how does it benefit the root zone?
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.
Does PRO-MIX® CX plant-based packaging respond to water the same way as the Eco-One® plastics when fluffing up?
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.
