I find the lactobacillus spray wash quicker and less labor intensive than regular washing. Plus it’s nice that it can be done at any point in the growing process, as needed or even repeatedly.
In theory this is potentially a safer option for seriously ill patients. When we use any kind of sanitizing process, we run the risk of eliminating all but the strongest and most harmful microorganisms.
I’m not sure what wash method you use, but a lot of people use hydrogen peroxide or baking soda to sanitize their harvested buds.
The main difference is that instead of attempting to sanitize the buds, I am replacing any bad bacteria with harmless / beneficial competitors that will literally eat bad bacteria and pathogens. This is also a simple form of covid precaution, some lacto bacillus eat pathogens including cold and flu viruses.
I am basically just physically cleaning them by misting them at close range with a simple food grade hand sprayer using a decent amount of pressure to rinse and irrigate the buds. This should also combat any fungal spores.
And lastly, I have no proof of this, but in terms of a safe and controlled drying process, I think it is less risky to get flowers on a live plant wet than it is to dunk harvested buds into water.
And again, I have no proof of this, but I would feel a little weird about dunking seeded buds after they have been chopped. I know that rain and foliar feeds do not harm ripe seeds growing on a live plant or interfere with the seeds drying process.
