Disclaimer : I'm still considering myself a newbie in this area, as there's so much reading to do, but I think it could be interesting to talk a little bit about that, since it's a subject I'm not seeing that much in forums, despite being something really benificial for our plants.
To simplify things, let's say we have 2 categories of bacterias :
- Bad Bacterias
- Beneficial Bacterias
Most common bad bacterias found in our plants are :
- Botrytis Cinerea (Bud Rot)
- Pythium (Root Rot)
(I let you google the terms if you need more scientific infos about them).
So now, let's talk about the good stuff :
Benificial Bacterias
There's a lot of benificial bacterias. I won't go into details for all of them, first because I don't have enough knowledge, and second because this would probably be too long.
But let's talk about the most important ones :
- Bacillus subtilis : B. subtilis bacteria produce antibiotics, including some called iturins, which help the bacteria compete with other microorganisms either by killing them or reducing their growth rate. When applied directly to seeds, B. subtilis bacteria colonize the developing root system, competing with various disease organisms that attack root systems. According to the manufacturers, B. subtilis also inhibits plant pathogen spore germination and interferes with the attachment of the pathogen to the plant. When soil or seed-applied, it is claimed that B. subtilis feeds off plant root exudates, depriving disease pathogens of a food source.
B. subtilis is also reported to induce systemic acquired resistance (SAR) against bacterial pathogens. SAR is when a plant’s own defense mechanisms are induced by prior treatment with either a biological or chemical agent. The concept of SAR has been studied for many years and is an exciting prospect for disease management. (Source : http://www.growingmagazine.com/fruits/bacillus-subtilis-for-disease-management/)
I haven't looked much into growing it yourself for now, I came to this webpage but I didn't made more research so far :

- Trichoderma spp :
Trichoderma spp are fungi mostly found in soil and root ecosystems. It is used in biological agriculture as a control agent against various plant diseases, including Pythium and Botrytis.
Trichoderma is also able to colonize the rizosphere, which means it can help in roots development as well.
Trichoderma detect other fungi, grow towards them, and attach and coil around the fungus, then produce enzy,es that destroy the cells walls of the target fungus (Source : https://manicbotanix.com/root-disease-prevention-and-management/2/)
Trichoderma seems to be pretty easy to cultivate yourself. I won't go into details cause I haven't tried it yet myself, but I'm planning to start testing in the coming months.
So that's it for now. I would be really interested to know if some of you are trying to cultivate those bacterias themselves, and how ? How do you cultivate, How do you use them and where (soil, hydro, coco ?)
There's various products you can find at your hydrostore claiming that you're buying beneficials bacterias, where in fact, you're buying just plain water, cause the bacteria's shelf-life is pretty short. (Yes especially you AdvancedNutrients, you probably managed to sell the most expensive bottled water those last years with you Pirhana/Voodoo/Tarantula shit).
Don't belive me ? Attached are LAB results from Oregon's Agriculture Department where they tested a bunch of products claiming to have beneficial bacterias. (Source : https://manicbotanix.com)
So that's why I'm interested in making this myself and speak with others already doing it :)
