Im finally gonna be trying this soon as well, got two bags of bk sittin in my back room. Gonna do a lower spawn ratio with just a qt of toc and however much more i need for a decent little tub simililar to bods unmoddeds. Maybe even try makin a pan cyan Ms agar slurry and try something with that as well

last night tubbed 1qt of WBS spawn to about 200g coir, half a beer cup of black kow shit, handful of coarse verm. I did steam prep all the sub a la bucket TEK it smells lovely. update in a couple weeks or less hopefully.

I tried it and got pins but fruits didn't mature, but that may have been my fault as well.

Trying again now with p. tropicalis. Few small trays and a little patch near the garden.
The patch is just BK from the bag and a bit of straw. The BK for the trays was pasteurized this time.
My last fails, also dont think was all kows fault.
Everything looked, smelled, and felt great when mixing it all together today, so maybe theres something to post back with.

Has anyone tried this with generic store bought cow manure as apposed to this specific brand? I'm doing it outdoors but it doesn't really count.

Yes Black Kow is a GREAT substrate and pre-sterilized is a HUGE plus because you can literally go to bulk right out of the bag. They have it at Home Depot for $5.65 for a 50lb bag and yields from it are great! I do a 70/30 mix of B.K. & Verm and anyone that says it wont or doesn't work OBVIOUSLY has NOT tried it before because its cheaper, easier, and produces better yields than any Coir/Verm tubs I have ever ran. I have experimented with other mixes as well but the best so far has just been the B.K. & Verm 70/30 with a 1/4" "Casing" layer of coir. If you haven't tried it, try it. You WILL be happy.

Black Kow has arrived at the local big box stores, sourced from FL. I’ve read through this thread and didn’t really catch on to field capacity. Open the bag and throw in some verm? Any success with P cyan grows, still pasteurize just because?

I get results with half BK half Coir/verm but same results with just coir. I use it cause its cheaper than coir.

I decided to give the Kow a shot. I had high hopes.
The kow I bought locally was quite clean and consistent and even looked like it had a bit of sand mixed in - a really nice texture. I took it straight out of the bag and added filtered water to bring it to field capacity. It didn't take much water to get there... I'm doing 6qt shoeboxes and it took maybe half a cup of water max per box for 3 pints of kow.
I used clone genetics (koh-samui) that I'm quite familiar with growing on coir so that I could notice the difference.
The first thing I noticed was that the mycelium was extra brilliantly white and pristine and rhizomorphic. The second thing I noticed is that the kow colonized faster vs coir but the kow took longer for pins to form. The third thing I noticed was that the fruits were bigger on kow than coir but the canopy was quite sparse. Weight per box was way down on kow vs coir.
Here is my first flush on Kow:
Vs what my first flush of the same genetics looks like on Coir:
And here is second flush on Kow (this pic was taken about 12-24 hours before harvest which is why the caps look a bit different vs on the first flush Kow pic):
I didn't use vermiculite but might try that, and I also didn't pasteurize or sterilize the kow. I may experiment and try all three, but if I need to pasteurize or sterilize the kow then I'd need the results to be better than coir to justify using it.

Cool post, and it is very refreshing to see someone post their results, and experience with it. Ive stopped advocated its value in mycology. I love it because it saves me time, and it is cheap, more bang for your buck! Im glad to see people still check it out. Thanks for your input, and time!

Why have you stopped advocating it? Do you still use it yourself?
I definitely want to keep experimenting with it and see if I can find a formula or technique that gets me better results than coir.

Man I wish it was decent around here, every time I buy it it smells like a bag of ballsacks and goes bacterial even after a pasteurization.

lol bag of ballsacks.
There's a few other things I want to mention......
First is potency. I have not had a chance to eat any of the mushrooms I grew on black kow yet, but they do SEEM to stain a lot more blue than my coir grows do. I usually take the time to trim the very bottom off the stem to ensure no coir or kow residue on the finished and dried mushroom - take a look a the little stem piece I trimmed off and note how crazy blue it is staining!
Second is density - I notice the stems of the mushrooms grown on kow feel hard as a rock. They feel like a radish or a turnip almost.
Third is possible contams. Note in the following pics that for my second flush, the mushrooms ONLY grew from the liner - they were actually attached to the side of the liner just above the substrate brick (the shrooms on the bottom right look like they are growing from the brick but the stems connect to the liner right on the edge like the rest of the fruits in the pic). Not a single mushroom in the second flush grew from the top of the brick itself. Also note the strange white fluffy growth on the surface. The purple staining you are seeing are spores from the first flush, and some of that white growth looks like it might be turning blue/green but you'll just have to trust me that it's not and it's the lighting in the photo - it looks bright pure white in good light. It's been there for about two weeks now so it can't be trich I don't think? Maybe it's just cube mycelium that doesn't want to pin - I have no idea. Anyone have any ideas?

1) blueing is not a sign of potency. It's an unrelated chemical that oxidizes blue. Even some non actives bruise blue, in oldy times it was a dye.
2) This is 2 fold. Genetics will determine how hollow or full the fruits are. How soft a mushroom is depends on how mature it is; younger mushrooms still growing are firmer, around maturity they start to soften. Just a couple days can make a mature mushroom soft enough to start falling over.
3) I'm not used to black cow. Generally contam issues early in a grow are from the spawn as long as your sub was prepped correctly. There could be issues with BK I'm unaware of though.

Good info thanks. Definitely did not know that about blueing so glad to have that info now.
As for #2, this was a clone grow from genetics I grow all the time on coir. I always harvest right after the veil breaks, so between those two things, the only thing different is coir vs kow, so I'm pretty inclined to think the kow has something to do with it but I guess there could be other variables - I just don't know what.

Could still be genetic variables. A clone usually still has a bunch of genetics and sectors.
But it does make it more interesting. Perhaps it is how your clone reacts to the different substrates?
