Microbes, Nutrients and Grow Cycles

Homegrown PotCast
July 02, 2020

In Homegrown Cannabis Co.’s inaugural PotCast, host Derek LaRose is joined by fellow grower @organigrower0624 to discuss a number of topics related to growing cannabis plants, including the benefits of using microbes and nutrients and details on grow cycles.


Though microscopic to the human eye, microbes are microscopic organisms such as the bacteria and fungi which form and develop at the bottom of the plant (in the root mass). Microbes have a symbiotic relationship with cannabis plants, they help plants absorb key nutrients like nitrogen, phosphorous, calcium, magnesium, sulphur and potassium. Microbes really speed up the absorption of these key nutrients and help the plant grow into a much fuller and better plant.

Without microbes, the cannabis plant’s roots will grow as normal, somewhat sporadic and spreading throughout the soil. Microbes act similar to a net, they spread wide through the soil and capture all the nutrients before latching on to the ends of the roots, allowing the cannabis plant to absorb the nutrients easily, like a sponge.


In the PotCast, a number of nutrients are discussed, here are a few examples:

  • Nitrogen: Promotes healthy growth in the leaves of the plant.
  • Phosphorous: Vital for the protection of the plant and maintaining the overall structure.
  • Potassium: Improves the marijuana plants ability to absorb water during photosynthesis.
  • Calcium: Builds the cell walls of the plant and gives the plant stability, allowing it to hold heavier amounts of bud.

Grow Cycles

When it comes to building your grow there are two main options presented to new growers.

Derek looks at the difference between hydroponic growing and soil growing. It is commonly considered easier for novice growers to use hydroponics when growing marijuana plants. However, Derek does not think this is the case. Hydroponics can be very expensive to set up. Furthermore, there are potential problems such as pH imbalances that can easily occur in hydroponic grows and can be difficult for beginner growers to deal with.
