The Just Cannabis Craft Cannabis Cocopeat Soil is a high-quality coconut husk substrate (also commonly known as cocopeat) product. Just Cannabis potting soil is a high quality pre-enriched cannabis growing medium. It is perfect for seed sowing, cuttings and potting-on. Because of the unique qualities of Just Cannabis Potting Soil, less water is required compared to other potting soils and growing mediums. Just Cannabis Potting Soil is the potting soil of choice for many established and experienced cannabis growers.

Coco Peat is also known as coir, coco fibre or coir peat. It is made from coconut husks and is a consistent media for long term growing. Cocopeat has excellent water retention ability and can be used multiple times. Coco peat generally has an acidity in the range of pH –6.0 – 6.5. It is a little on the acidic side for some plants, but many popular plants can tolerate this pH range.

Cocopeat has a negatively charged complex, surrounded by a couple of positively charged ions: sodium and potassium.


No additional fertilizers are also required.

General Directions:

Germinating Seeds:

Fill the seed tray with Just Cannabis Potting Soil. Level off and firm lightly. Water thoroughly using a watering can with a fine spray and allow to drain. Make a small hole in the medium of approximately 1cm deep and carefully place the cannabis seed in the hole. Keep the soil moist, but be careful not to overwater – especially during the early stages right after germination. Once the seedlings are large enough to handle, pick them out gently. Pot in the final growing pots using Just Cannabis Potting Soil.

Propagating Cuttings:

Water the parent plant 24 hours before taking cuttings. Use a sharp knife to cut off young shoots, trimming each one just below the leaf joint by removing the lower leaves. Dip the bottom end of the cutting in a suitable rooting hormone as per the manufacturer’s directions. Fill pots or containers with Just Cannabis Potting Soil and level off. Make holes in the growing medium and insert the cuttings. Firm gently around the plant and water well using a watering can with a fine spray. To help your cuttings to establish, cover each pot with a clear polythene bag to avoid a moisture loss. Put a few small holes in the bag for ventilation and do not allow the leaves to touch the polythene. When a healthy root system has developed, remove the bag and water.


Fill pots loosely with Just Cannabis Potting Soil. Plant with the minimum of firming. Water plants well so that all the growing medium is moistened. Please remember to take care with fragile roots.


Just Cannabis Potting Soil will supply all the nutrients needed for strong healthy growth during the entire life cycle of the cannabis plant. During the flowering stage of the cannabis plant, a mixture of blackstrap molasses and Epson salt can be added to the medium as an optional extra to help further increase bud density.  The recommended ratios are 5ml sulphate free blackstrap molasses to 1L of water and 1ml of Epson salt to 1L of water, up to twice a  week during the flowering stage.


Adequate watering is essential to your cannabis plant’s health. Keep the growing medium moist, although not consistently over–wet, particularly during the first few weeks of the plant’s life. Avoid drying–out of the growing medium and if this occurs, ensure sufficient re–moistening. The optimal pH range of water for cannabis plants is 6.0 to 6.5.
