Using water additives in spray or humidifier to keep contaminants out of Fruiting Chamber * 1
    #26691684 - 05/24/20 03:05 AM (3 years, 8 months ago)

I am new here and a novice grower so I am afraid to really experiment just yet but I love a good experiment. But it seems like contamination is an ever present danger especially for those without lab equipment. 

Surely to God there are some water additives that can mitigate or remove the contamination problem altogether without killing the mycellium.  Off the top of my head: garlic, bee propolis,tea tree oil, cinnamon, cloves, orgegono oil, etc. ad infinitium.  Nature is smart does anyone know how to use it.  It doesn't have to be strong, just enough to slow the bad stuff.

I have done diluted bleach dunks and my mycellium didn't die.  Maybe I am just an idealistic newcomer who thinks there's an answer. I feel like there's so much mold and shit in the average home that contamination can't be prevented unless you have a lab.

What about Jesus? Are you all familiar with the power of prayer?

I just run straight water in my ultrasonic and clean it out every now and then. You probably could add some H2O2 to the water to keep your humidifier clean. I know the pot guys use it lots between cycles in their hydro grows. It comes at around 20% concentration and you would likely want to dilute it to 0.25-0.50%, maybe less. I have sprayed solution at 3% directly onto mycelium and it didn't kill it. To be clear, I've never put anything in my humidifier and don't feel the need to, but if I were to try something, H2O2 would be my first thing.

If your humidifier is inside your grow area, I wouldn't think it is the source of contamination unless it is dirty. If you are using a pressurised tub with an ultrasonic outside the grow area, you could use a pre-filter to help keep things out.

I have found that contaminations tend to come from earlier steps in the grow process. Once your mycelium has fully colonised your substrate, it should be able to fight off contams on it's own for at least a couple flushes.

You probably would get more replies with this thread in the general cultivation forum. Not really an advanced topic. Happy cultivating.

You prevent contamination with healthy substrates. Healthy substrates go 3+ flushes easily without molding. You can spit on a healthy substrate

I used the sunbeam ultrasonic humidifiers inside a small 4 tier greenhouse and after a couple grows I took it apart and it did have black mold or some type of mold growing inside it. They pull the air from under the unit with a blower fan and direct that up piping and out the top. The vent holes on the bottom where the air is drawn into the blower fan for the humidifier is also open to all the electrical (which is mainly an AC/DC transformer and the PCB/components for the ultrasonic disc). After I noticed this I stopped putting it inside where the humidity is to prevent an electrical short and reduce the amount of active mold growth and mold spores from forming inside the unit.

I've since built a totally different humidifier which is sort of based around how those sunbeam ultrasonics work and started to add H202 to the water at the rate of about 3-5ml 29% H202 to 3.78 liters, to keep it fresh, as the gravity fed reservoir is 18 liters and where the ultrasonic disc is located is about 5 liters. This is the same rate that is used in hydroponics water systems and apparenlty helps to fend off bacteria and algae from growing in the water system. It should be added at the same rate every 3-4 days, as it degrades quickly. But I doubt it will actually prevent any mold growth from growing. Fresh circulating air, even in a very high humidity environment is apparently the best way to prevent mold from growing, as most mold and fungus need high c02 to grow their vegetative stage, from what I understand.

But as bodhisatta and piggypie said healthy substrates shouldn't contaminate quickly.
