Lost Everything to Fungus

[Capn-Crunch]

For the last 2 years I've been growing in the same peat moss medium because all the garden centers here have not had any promix.
Every plant of 2 different strains came down with a systemic fungus issue and died 4 weeks into flower.
I tried spraying hydrogen peroxide, baking soda and water, and Daconil. Nothing stopped it.
I'm thinking of doing a bleach and water flush to sterilize the medium, then a soil drench with Revitalize.
Is this a good idea or not?

How are you sure it was 'fungus'. Personally I've never heard of someone loosing mature plants to fungus suddenly.....unless it's outdoors. Do you have any pics of said fungus?

It was absolutely a fungus issue. I'm pretty sure it was Sclerotinia sclerotiorum and it was coming from infected growing medium.
I've been growing for a long time and have never run into this issue before.
I have no actual pics but looked exactly like this.

Bummer. I have stopped buying soil from garden centres, or anywhere that stores it outside. I was forever getting fungus gnats. I have swapped over to Plant !T Pro from Amazon. It is dry stored and is delivered dry.

It pisses me off that I keep the inside of my tent and all of my kit completely clean and sterile, only to be thwarted by the products I buy to grow them in.

Sorry for you loss, I have never had a fungus problem indoors, I imagine that it is going to be a big job to sterilise and reset everything to stop it coming back.

Your saying you cant find promix in maine? I see it in every hardware,garden center an big box store that i shop at. Dump that nasty old stuff an take a ride.

What were your growing conditions like besides the media? I'm not saying the media wasn't the source, but healthy plants do a good job of staying healthy unless something is off in the environment. Could you provide more details about the room it was in, like, is this inside a house or outbuilding, what temps/RH were running, ventilation/air circulation?

I'd throw out all that media, sterilize every surface in the room, maybe consider getting a hepa filter for the room as well, to keep spores out of the air-mold like that isn't healthy for you either. Also, I suggest treating your plants with a rhizobacteria product that has 3rd party potency test results available, like Tribus. Not cheap, but the small bottle would be enough to treat your next cycle-I'd treat the media once per week and the plants every other week with it until you go to 12/12. Depending on where that room is-inside or outside a living area-you might consider one of the greenhouse ozone type sterilizers too. Next time, lollipop your plants, and trim all leaves that are below the canopy and not getting light. I'm not sure what your RH is, but you should keep your Dehumidifier below 50%....if you were trying to follow VPD, I'd say, lowering your RH is more important. Good luck to you!

I feel dirty just looking at that pic. I never go into the MJ Plant Problems for that reason. Bad juju.
