Solid fertilisers or solid nutrients, whether in powder, granules or tablet form, are an excellent option for both indoor and outdoor cultivation, meaning plant nutrition is as easy as can be during cannabis cultivation.

As a general rule, solid fertilisers should be mixed into the substrate before planting. The plants will then feed from these slow release organic fertilisers, containing all the macro and micro nutrients that the plants need in the different stages of life: growth, stretch, flowering and maturing.

A well-amended substrate means you won't need to worry about using liquid fertilisers at any point, simply irrigate with the right amount of water each time. To take better advantage of solid organic fertilisers (there are also solid mineral fertilisers) and increase their availability, you can use microbial supplements which include beneficial bacteria and fungi like trichodermas, endomycorrhizas and others.

We can also supplement them with root stimulators, in growth and flowering. The amount of fertiliser we mix into the substrate will vary depending on whether we have a long growth period such as in outdoor cultivation or if it is a rapid harvest as with indoor growing. It's very easy to add more nutrients, either when we carry out transplants or by top-dressing the surface of the soil, and mixing into the first few centimetres of the substrate.

This type of fertiliser is ideal for beginners who are new to cannabis cultivation and want a grow that's easy to manage, but also for those who seek the best quality flowers, as well as for those looking for simplicity and effectiveness in their garden.

There are several brands of solid fertilisers, in organic and mineral format, shown below, some are complete by themselves as for example Bio Tabs, Powder Feeding, BioGrow and BioBloom, among others. Other fertilisers should be complemented with other amendments, as with the Guanokalong brand, where we can find ingredients like guano, palm tree ash, among others.
