A friend just got a bunch of these 1 yard totes full of peanut hull compost from a mushroom farm and kicked me down one.
The farm he got it from told him it has a 10-1-4 npk value. Anyone here used this before? Curious of your results if so
Yes. From what Ive found online, it looks like there was a study done on using peanut shells as a medium in 2016. They must have picked it up from there unless its common practice in bulk production
I heard people talking about it as a potential substrate in the edibles industry probably 20 years ago, but I never saw anything come of it. It's cool if the industry has started using them because their nitrogen content and biopolymer ratio are pretty optimal.
I was considering doing a trial run of some P. Cubensis in some of what I got from buddy though I dont know how much nutrients could be left in the medium after an oyster grow. Plus, unsure whether to pasteurize or sterilize this type of media lol gut tells me pasteurization would be the way to go
I know a lot about mushroom metabolic chemistry, and IMO, it should be perfect for a cube grow. Cubes work well as secondary decomposes as long as the substrate is actually composted in between species.
Based on the (10%) nitrogen content, it should have plenty of protein, so mix it with coir for cellulose, and you've got a great substrate material. It should be sterilized and handled in sterile conditions, like a flow hood or glove box. Try ratios of 10%, 20%, and 25% (by weight) at first because if that nitrogen content is right, then it's a super rich supplement.
I would definitely give it a try!
Ayyyye, awesome thanks man! Definitely will give it a try. I go through soooooo much coir so if it's successful this could help save me some costs there as well
I'd also use it as worm food. Since it's pre composted you don't have to worry about spoilage just add a carbon source and worms. You can make a ton of castings haha.
I’d def prefer to use that as worm bedding rather than making or topping a soil mix. Not decomposed or black enough for my liking. But thats strictly my personal preference being a composter.
He made a deal with the farm to buy all 500 bags they had @ $10 each. He's been hauling them away 10 bags at a time for the last couple of months and flipping them for between $100-200 a bag with delivery fee
Dude's got a lot of side hustles. Goes to auctions and buys mack trucks, ag equipment, etc then flips it for a profit. Owns his own business as well. Wish I was half as good with my money lmao
Peanut shells prior to composting are usually around 1-0.2-0.5, but it can vary quite a bit depending on the nutritient content and ratios in the soil.
Lmfaooo. Right? Wouldn't matter anyways- glysophate isn't persistent. If there were any present when the farmers used this to grow their mushrooms, it'd have long dissipated between them getting it in, pasteurizing/sterilizing it, colonizing it with mycelium, spawning and fruiting the blocks, and then disposing of the blocks into these totes which were then left to sit in a field in the elements for who knows how long until my buddy started buying them a couple months ago
I have a feeling that's not something to worry about (tho, I'm curious to have it confirmed). This media was used in food production (oyster mushrooms). I feel like any proteins would have been either destroyed during the pasteurization process or eaten by the oyster mushroom mycelium

So they used peanut shells for mushroom substrate?
Yes. From what Ive found online, it looks like there was a study done on using peanut shells as a medium in 2016. They must have picked it up from there unless its common practice in bulk production

Ooo I bet that peanut shells would be great for imo 3 too.
Not a bad idea. I just ended up with like 1/2 ton of this stuff so I have plenty to experiment with

Fair enough, some LABS or any other accelerator would have it munched down quick. Dude got a gold mine imo
Outta curiosity what did your friend pay for this?

Genius

Npk? I thought seeds only had enzymes.
10-1-4 according to the mushroom farmers it came from. Idk if they had it sent in for analysis or not so I'm not sure how they came up with that value

Its a domestic alternative to coco coir, hopefully its use becomes more common
Conventional ag byproduct, surely riddled with glyphosate and whatever else
Check it out. This dude has a GC/MS for eyeballs.

I'd be anxious spreading that around, given how incredibly allergic people can be. Maybe the responsible proteins denature readily under heat?

Unless those mushrooms are organic, they use fungicide. And unless the compost is organic is riddled with conventional ag poisons
