In this category you will find our full range of organic nutrients for the cultivation of cannabis. In the world of science, organic is defined as a substance containing carbon, derived from living organisms, be they animal or vegetable. However, in organic gardening, this definition has been expanded to include mineral products derived from naturally occurring sources such as rocks and those products permitted for use in organic gardening by the various organic certification bodies throughout the world.

The use of organic fertilisers will feed the substrate at the same time as feeding the plants, slowly and consistently releasing nutrients into the soil, improving structure, increasing organic matter content and encouraging the proliferation of beneficial soil microbes like bacteria, fungi, nematodes, etc.

Organic cultivation has much less environmental impact than using synthetic nutrients, which are sourced from petrochemicals and require large amounts of energy to produce. Not only this, but many growers claim that cannabis grown using organic nutrients has a superior flavour and aroma than that cultivated with mineral fertilisers.

As a general rule, organic fertilisers are less concentrated than mineral fertiisers, and they release their nutrients to the plants at a more slow rate, made available to the plants once processed by the microbial population in the substrate.

Organic nutrients are available in liquid and solid forms, and are intended for use in soil systems in which hand-watering is carried out. This is because organic fertilisers will tend to solidify and clog the automatic irrigation systems used in hydroponic cultvation.
