Why You’ll Love This Recipe
The CVG substrate recipe is a game-changer for anyone aiming to create an ideal growing medium that balances water retention with proper drainage and aeration. Unlike traditional soil mixes, CVG substrates minimize the risk of root rot while maintaining moisture levels that plants thrive on.
This recipe is especially loved for its versatility across a wide range of plants, from tropical to desert species.
By mixing coir, vermiculite, and granite in just the right proportions, you get a substrate that encourages roots to breathe, absorb nutrients efficiently, and anchor firmly without compacting over time.
Plus, it’s easy to customize with additives like perlite or organic fertilizers based on plant needs.
Ingredients
- Coir fiber – 4 parts (provides excellent water retention and organic support)
- Vermiculite – 2 parts (improves moisture retention and aeration)
- Granite grit – 1 part (ensures drainage and prevents compaction)
- Optional: Perlite – 1 part (for extra aeration, especially for succulents)
- Optional: Organic compost – ½ part (for nutrient enrichment)
Equipment
- Large mixing container or tub
- Measuring cups or scale for accuracy
- Gloves to protect hands
- Garden trowel or scoop
- Storage container or bags for substrate
Instructions
- Prepare your workspace: Choose a clean, flat surface to mix your substrate. Wear gloves to avoid irritation from coir fibers.
- Measure ingredients: Using the measuring cups or scale, measure out your coir fiber, vermiculite, and granite grit according to the ratios listed above (4:2:1).
- Combine coir and vermiculite: Place the coir fiber and vermiculite in the mixing container. Use a garden trowel to blend them thoroughly until evenly distributed.
- Add granite grit: Slowly add the granite grit to the mixture and continue mixing. The granite ensures good drainage and prevents the substrate from becoming compacted.
- Optional additives: If you want extra aeration, mix in perlite. For nutrient boost, add organic compost and blend well.
- Check moisture level: Moisten the substrate slightly with water, but avoid making it soggy. It should feel damp but crumbly.
- Store substrate: Transfer the finished mix into storage containers or bags until ready to use. Keep it in a cool, dry place to maintain freshness.
Tips & Variations
“Customizing your CVG substrate based on the type of plants you grow can maximize their health and yield. For orchids, increase coir slightly for moisture.
For succulents, add more granite and perlite for drainage.”
Here are some additional tips to make the most of your CVG substrate:
- Pre-soak coir: If using dry coir, soak it in water overnight before mixing to ensure optimal moisture levels.
- Adjust particle size: For smaller pots, use finer granite grit; for larger containers, larger grit works best.
- Sanitize components: To avoid pests or diseases, you can bake vermiculite and granite briefly at low heat before use.
- Reuse substrate: CVG substrate can be rejuvenated by adding fresh coir and compost annually.
Nutrition Facts
| Component | Role | Nutrient Contribution |
|---|---|---|
| Coir Fiber | Water retention, organic matter | Low in nutrients, primarily provides structure and moisture |
| Vermiculite | Moisture retention, aeration | Contains magnesium and potassium, minor nutrient supplier |
| Granite Grit | Drainage, aeration | Inert, no nutrient contribution but improves root environment |
| Organic Compost (Optional) | Nutrition, microbial activity | Rich in nitrogen, phosphorus, potassium, and trace minerals |
Serving Suggestions
While CVG substrate itself isn’t edible, the plants you grow in it can be! Use this substrate to cultivate healthy herbs, succulents, or flowering plants that can brighten up your home or garden.
Try growing kitchen herbs like basil, mint, or rosemary in pots filled with this substrate for fresh flavors on demand. Succulents planted in CVG substrate make charming desktop companions that require minimal watering.
