Just Cannabis – 30L

(1 customer review)


Specifically Formulated & Enriched for Optimal Cannabis Growth

Available on back-order


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.

    Delivery and service was great. All growing mediums i purchased from happy harvest reak of amonia(sign of lack of oxygen) very disappointed as I’ve had great results with this soil before and never has it smelled like this which leads me to think that it’s the storage conditions of the mediums. The vermicompost was so bad that it was white and ashy in the center
