Beneficial Bacteria for Cannabis

beneficial bacteria for cannabisPretty much every single time of soil has some sort of fungi in it, which can either be beneficial or very bad for plants. These fungi work by connecting to your plants’ roots, and the fungi essentially enters into a symbiotic relationship with your plant. This is an incredibly potent way to protect and feed your plants, and this type of relationship essentially makes most life possible on the planet. Microscopic life is powerful enough to eradicate the entire planet, after all.

Types of Fungi and Beneficial Bacteria for Cannabis

We’re going to have a look at various different type of fungi and beneficial bacteria used when it comes to growing cannabis and the differences between them; there are thousands of different types of fungi and bacteria, all of which have their own functions.

Endomycorrhizal Fungi:

Endomycorrhizal fungi are types of fungi that actually get into your plants roots and begin getting to their cells too. These types of fungi can’t be seen, but they’re used just as much as Endomycorrhizae

  • Glomus intaradices
  • Glomus mosseae
  • Glomus etunicatum
  • Glomus aggregatum
  • Glomus clarum
  • Glomus mososporum
  • Paraglomus brazilianun
  • Glomus deserticola
  • Gigaspora margarita
  • Trichoderma koningii
  • Trichoderma harzianum

Ectomycorrhizal Fungi:

Ectomycorrhizal Fungi are types of fungi that don’t actually get inside the colonized roots; they stay on the outside of the root system and can be seen without the use of a microscope. If you were to wash out a root system with this type of fungus attached to it, you’d be able to see small dots stuck to the roots.

  • Pisoliyhus tinctorius
  • Rhizopon fulvigleba
  • Rhizopon luteolus
  • Rhizopon villosullus
  • Rhizopon amylogopon
  • Esclerodermia citrinum
  • Esclerodermia cepa

Bacteria and Micro-organisms

Bacteria are microscopic beings that essentially decompose minerals so that your plants’ roots can easily absorb them, as well as attracting atmospheric nutrients to the soil. On the other hand, they also produce a certain amount of stimuli for plant roots, as well as protecting them and the plant itself from various different insects and microorganisms, including damaging nematodes.

  • Azotobacter chroococcum
  • Bacilus subtilis
  • Bacilus licheniformis
  • Bacilus azotoformans
  • Bacilus negaterium
  • Bacilus coagulans
  • Bacilus pumilus
  • Bacilus thuringiensis
  • Bacilus amyloliquefaciens
  • Paenibacillus durum
  • Paenibacillus polymyxa
  • Pseudomonas fluorescens

Harmful Fungi and Bacteria for Cannabis Plants

When growing cannabis, as well as knowing which fungi and bacteria are beneficial for cannabis, you’ll also need to be familiar with fungi and bacteria that harm your cannabis plants in order to stop this from happening. Cannabis plants are always vulnerable to fungi or bacteria infestations, which is why it’s a great idea to use preventive products.beneficial bacteria for cannabis

The different types of fungi that can severely damage cannabis plants, especially their roots, are pretty well-known nowadays, and we have a whole post regarding what they are and how to prevent them – click here to read it. We’re going to have a closer look at the various types of damaging bacteria that can infect your plants; thanks to the genetic makeup of cannabis and the wide amount of preventive and combative products that are on the market, bacterial infections are pretty easy to deal with in cannabis plants.

Epiphyte and Endophyte Microorganisms

Just like with fungi, which have two types (those that stay outside the roots and those that infiltrate them), bacteria also have two different types; epiphytes and endophytes. Epiphytes are bacteria that develop on the top of your plants’ substrate, and endophytes are bacteria that live within your plants.

Damaging bacteria for cannabis plants:

We’re only going to name a few bacteria, as these all englobe hundreds and thousands of sub-species of bacteria.

  • Erwinia amylovora
  • Xanthomonas campestris
  • Pseudomonas cichori
  • Erwinia caratovora sp. caratovora
  • Agrobacterium tumefanciens

How Bacteria can Damage Your Plants

The first thing to keep in mind is that you can’t see bacteria with the naked eye, so you won’t even know that your plants are infected until they begin to show symptoms – bacteria can be found in the air, in water, even on your skin. When it comes to how bacteria shows up on plants, it can cause issues such as staining, rotting, bad smells or even weird growths on the trunk. We’re going to name a few of some of the most common symptoms.

  • Staining
  • Mosaic disease
  • Deformed areas
  • Growths on the trunk
  • Poor yield and poor root/vegetative growth
  • Dead cells on leaves, stems and trunk
  • Withering
