Plug Life Peatmix and Plug Life Coco are professional RHP-certified substrates for seedlings and cuttings. Peatmix offers superior moisture retention, while Coco provides maximum aeration. Both ensure a stable pH and low EC, driving explosive root development and vigorous plant growth for a perfect start in any hydroponic or soil system.
Establish the perfect starting point for your cultivation with the Plug Life range of professional propagation substrates. Whether you prefer the traditional water-holding properties of a Peatmix or the high-aeration benefits of Coco, these media are engineered to provide the ultimate environment for seedlings and cuttings.
Both blends are RHP-certified, ensuring they are free from pathogens and pests while maintaining a stable pH and low EC. By choosing a high-quality starter medium, you ensure vigorous plant growth and a robust root system before transplanting into larger pots of potting soil or coco-based systems.
Key Benefits of Plug Life Substrates
- Rapid Root Development: Both mixes are structured to encourage fast lateral root branching and dense root hair formation.
- Optimal Air-to-Water Ratio: Designed to prevent compaction, ensuring roots have constant access to oxygen while maintaining essential hydration.
- RHP-Certified Quality: Guaranteed consistency, cleanliness, and stability, reducing the risk of "damping off" or root rot in young plants.
- Low EC & Buffered pH: Specifically formulated with a minimal nutrient charge to protect sensitive young roots from nutrient burn.
- Versatile Compatibility: Perfect for use in propagation trays or as a standalone medium for small starter pots.
How to Use Plug Life Substrates
Using Plug Life Peatmix or Coco ensures a stress-free start for your plants.
- Preparation: Fill your propagation trays or small pots with the medium. Gently tap the sides to settle the substrate, but avoid compacting it to keep the oxygen levels high.
- Hydration: Water the medium before planting. If using Plug Life Coco, you may want to use a very weak nutrient solution or a root stimulant like Canna Rhizotonic.
- Sowing & Cuttings: Sow your seeds at the recommended depth or insert your cuttings after using a rooting gel.
- Feeding: Because these are starter mixes, begin using a dedicated young plant nutrient like Canna Start once the first true leaves appear to support vigorous plant growth.
- Transplanting: Once roots have colonised the medium, transplant into a larger volume of Ecothrive Coco Lite Mix or your preferred soil.
Available in Trays of 104 cubes.
Also available in the Plug Life range is Plug Life Big Phat Mother Pluggers (Coco Coir & Peat).
Frequently Asked Questions
Which is better for seedlings: Plug Life Peatmix or Plug Life Coco?
It depends on your watering style. Plug Life Peatmix holds moisture longer, making it more forgiving if you cannot water daily. Plug Life Coco provides superior aeration, which can lead to faster root growth but requires more frequent monitoring to ensure it doesn't dry out.Do I need to rinse Plug Life Coco before use?
No. All Plug Life products are RHP-certified, meaning the coco is already thoroughly washed and buffered to remove excess salts. It is ready to use straight from the bag for your seedlings and cuttings.When should I start feeding nutrients to plants in Peatmix?
Plug Life Peatmix contains a very light mineral charge to sustain plants for the first week. You should begin a low-strength feeding schedule with a propagation-specific nutrient as soon as the first true leaves emerge.Can I mix these with PLANT!T Perlite or Vermiculite?
While both mixes are professionally blended for immediate use, many growers add 10-20% Perlite to the Peatmix to further increase drainage, or Vermiculite to the Coco to help retain moisture during the delicate germination phase.SKU: 1572- Plug Life Peat Mix
