Rooting Mediums for Clones & Cuttings

Posted by Art G. on

Choosing the appropriate medium for planting a clone is essential to ensure its healthy root development and growth. Here are some of the best mediums to consider for starting plant clones:

1. Rockwool Cubes:

  • Pros: Sterile, porous, and retain water well.
  • Cons: They can sometimes retain too much water, leading to oxygen deprivation for roots.

2. Coconut Coir:

  • Pros: Sustainable, excellent air and water retention, and has a natural rooting hormone.
  • Cons: It can be too dry sometimes and might require frequent watering.

3. Peat Pellets:

  • Pros: Easy to use, biodegradable, and have good water retention.
  • Cons: Peat extraction is not always sustainable, and pellets can sometimes be too compact.

4. Soil:

  • Pros: Natural, contains essential nutrients, and is familiar to work with for many growers.
  • Cons: Can contain pests or diseases and might not be as sterile as other mediums.

5. Aeroponic Systems:

  • Pros: Very high success rate, clean and rapid growth due to maximum oxygen exposure to the roots.
  • Cons: Technically complex and can be expensive to set up.

6. Water:

  • Pros: Simple and cost-effective; roots are visible, making it easy to monitor growth.
  • Cons: Risk of rot and algae growth; less oxygen availability to roots.

7. Hydroponic Systems:

  • Pros: Controlled environment, efficient nutrient delivery, faster growth.
  • Cons: Requires equipment and some technical knowledge.

Factors to Consider:

  • Sterility: The medium should be sterile to minimize the risk of disease and pest infestations.
  • Water Retention: It should retain enough moisture to keep the clone hydrated but not so much that it becomes waterlogged.
  • Aeration: The roots need access to oxygen, so the medium should allow good airflow.
  • Nutrient Content: While not crucial for initial root development, having some nutrients can be beneficial as the clone grows.
  • pH Balance: The medium should have an appropriate pH level to support nutrient uptake and root health.


  • For Beginners: Soil or peat pellets can be a great starting point due to their ease of use and availability.
  • For Intermediate Growers: Rockwool or coconut coir can offer a balance of water retention and aeration.
  • For Advanced Growers: Hydroponic or aeroponic systems can provide precise control over the growing environment for optimal results.

Remember to ensure that the chosen medium is moist (not soaking wet) before placing the clone in it and to provide the appropriate lighting, temperature, and humidity levels to support the clone’s growth.

Cloning Cannabis - Guide

Cloning a cannabis plant involves creating a genetic copy of the plant, ensuring the clone inherits the exact characteristics, potency, and yield as its mother plant. Here’s a step-by-step, highly detailed guide to cloning a cannabis plant:1.

The Benefits of Microbial and Bioactive Soil Amendments

Introducing beneficial microbes and organic or inorganic compounds can work wonders in improving overall soil health. Microbes enhance the soil structure, promote root and plant growth, improve crop health, increase water dynamics which can reduce salt and drought stress, prevent the loss of nutrients, increase the uptake of nutrients and water, and protect against disease and pests. Bacteria [...]

Mycorrhizae Crash Course

Most people and even some growers don't know what mycorrhizal fungi are. It is a fungus that forms a mutualistic and helpful relationship with plant roots. Mycorrhizal fungal filaments in the soil function as extensions of plant root systems and are more effective in nutrient and water absorption and delivery than the roots themselves. In essence, they bond with [...]
