freeze used coffee, pasteurize while making substrate. works fine for me growing 1 coffee can at a time.

I love your quote. "Nature is a beautiful thing we just need to grow with it".

[@urbanfarm-it]

Thanks! it is how we feel here at Uraban

[@gelhope5510]

Great beginner friendly video, been wanting to grow mushrroms for years. Tried coffee grounds but gave up as looked like mold took over. Threw mix into garden and days later had blue oysters popping up. Well happy but soon got munched by something. So now im trying again after seeing this

[@bryanwatt9751]

Thanks for sharing! You guys have the best resources!

[@toddwmac]

Your timing...or my timing... is perfect. As a new grower of mushrooms, I've been looking lately at my daily coffee ground use and the water bottles we pitch regularly. You've given me some good ideas. As a suggestion, you might encourage your viewers to use gloves. The nooks and crannies of the hands and nails combined with their flexing nature make them very hard to effectively sanitize and they provide a primary contamination vector w/in any sterile zone. Alcohol and a cheap pair of nitrile (in the US) gloves will go a long way towards keeping those nasty critters at bay. As far as rolling up your sleeves a clean long sleeve woven shirt is a better option. Skin sheds constantly, and in that shed are microbes you might not want in your grow. Thanks and best of luck to you guys!

[@urbanfarm-it]

hi mate, thanks for the feedback! as long as our viewers learn that cleanliness is key that is a win! Good advice there though and detail. i guess you may have learnt the hard way with contamination??

[@ronparker6489]

Nice job Mate. Will give it a try.

I bought some grain spore on a whim one night and this is way more complicated than I thought it would be. For an organism that grows in rotting logs, in the dirty, unhygienic woods behind my house, it sure is finicky.

[@urbanfarm-it]

Hi Andrea, growing on coffee requires more care than other methods because it is so nutrient dense. you can grow outdoors using spawn and straw and there isn't a need to pasteurise as long as you use the correct mix ratio. hope that helps! Kr Elliot

[@Tinker13ee]

@@urbanfarm-it Ahhh, I see, makes sense. I had just thought, 'hey it's fungus, probably not too fussy,' but nothing is ever that easy lol. I followed your video instructions nonetheless and I'm eager to see what happens. If it works, it works, if not, oh well I tried lol. Thanks for all the info!

Hi, loving all you videos, Ive been using straw pellets, rehydrated at 60%, what coffee pellet ratio would you advise?

[@urbanfarm-it]

It depends a lot on the grade of the coffee and straw. I would use a lower ratio of straw pellets than chopped straw as its very fine and easily compressed.

[@EFTforeverything]

When you have sprayed a mist of water, do you re-cover with liner?

[@babygorilla4233]

So for starting some from liquid culture and im going to try something. Ill sanitize my hands and drop the coffee grains streight into a freshly unsealed plastic ziplock bag. This should work i got a shelf in the basement for em it's quite damp. Actually do you think too much liquid in the bag is a problem its coffee grounds direct from the drip machine there was a bit of water in the bag. Its got holes for ventilation.

[@dscott8799]

Thx for the video. This was very informative. I’m wondering if you can pasteurise older coffee grounds, let’s say a few weeks old, or perhaps even dry your coffee grounds so there’s less chance of infection with moulds? I don’t drink that much coffee after all haha

[@urbanfarm-it]

Thanks! it really isn't advisable to leave it. However, if you are using a fast growing species like oyster and you use a lot of spawn thank you may just get away with it. it isn't so black and white to say that if you don't use it right away you will get contamination. but, if you can control a risk then you should do!

[@dscott8799]

@@urbanfarm-it Thx for replying .. let me get on it this weekend :D

[@trevorbaker9981]

I'm gonna use all natural hard wood saw dust as opposed to straw it's completely organic and free of debris and chemicals...I hope it works

[@trinidadcurtan7928]

Sir is it ok if i use cardboard as substrate for oyster mushrooms. Watching from 🇵🇭🐾🐕

[@Whisky.]

this might very well be a st*pid question but can't I freeze the coffee grounds instead of using it within 24 hours?

[@daveharris2677]

Have you tried using coffee chaff mixed with grounds rather than straw? I collect both fresh from a roaster/cafe so they would be pasteurised.

[@urbanfarm-it]

I haven't tried it myself, but I had a friend that did it! I believe that was chaff and sawdust though....definitely worth doing some trials. Let me know the result!

[@vzero_snexfur885]

Great video can I use alcohol to sterilize and do I use the tips and bottoms or just the bottom of mushroom

[@urbanfarm-it]

you can use alcohol on all of your equipment no problem! you can use the tops to eat as they are and the bases as a lovely stock!

[@foxybuddy]

How about the waste coffee grinds from coffee shop? Normally we put it for raised beds. Sometimes with some sugar included. Can I use that mixed with straws?

[@urbanfarm-it]

that is precisely what you need! just make sure it goes straight from the machine into a sealed container

[@sjewitt22]

I'd try putting it in the fridge for a day before fruiting to shock it.

[@allisonc6518]

I have left over coco noir from some indoor plants, do you think that would be a decent alternative to the straw?

[@urbanfarm-it]

you can grow oyster mushrooms on coir for sure!

[@DustBunny.101]

Hello there, I have been watching your videos, checked out your website to order but you don't ship to USA. Thank you for the informative videos. Wish I could buy your products

I've got a question.. what about aspen bedding for snakes? I might give it a go

[@urbanfarm-it]

I've never tried it, let us know how you get on!

[@said.skopal]

Wow.Can we grow any mushrooms except oysters on this way?

[@urbanfarm-it]

there are others (e.g. winecap) that you can grow on a coffee straw blend. However, most other varieties would be very prone to contamination when using coffee waste as it is so nutrient dense. so YES you can, but with more steps in the process to sterilise.

[@vzero_snexfur885]

Also I have used brewed coffee grind s I dried it in sun. ...so wer brewed coffee grinds are dried out , can I use reused coffee ground and do I need to sterilize coffee too? If so how do I do that thanks

[@urbanfarm-it]

best thing is to re-boil it to be safe!

[@ThinkPraise]

Can cococoir be used in place of straw? Thank you

[@urbanfarm-it]

I haven't tried it myself, but i expect that it would be absolutely fine as long as it was something vigorous like oyster mushrooms that you were using.

[@sjewitt22]

Can you keep coffee ground in the freezer or re-pasturize it?

[@urbanfarm-it]

You are definitely better off using freshly made grounds always. However, you could in theory re-pasteurise. if you did that I would use a higher mix rate of spawn to negate any extra competition

[@rodneyb7918]

Question, is that 20 degrees Fahrenheit or Celsius?

[@michaeldodge7293]

Well 20° F is Below freezing.. sooo

[@emmanuelalva6597]

I would I suggest not growing in a carpeted room at all. There’s a chance you have allergies to spores and they will linger in the room much longer and your sinuses will hate you.

[@barry4967]

How did you sterilize the paper towels?

[@urbanfarm-it]

Paper towel is clean from factory processing. be careful to use fresh towels rather than ones that have been knockign around in the cupboard!

[@jagtazman]

How much mixture grams fits into the coffee cup?

[@urbanfarm-it]

Hi Adam, That depends on type of substrate your using. Here a few hundred grams per cup is about right. you could get half a KG in there if using a fine blend.

[@Pmomma100]

Ok call me crazy but you don't know things unless you ask but why all the sanitation when they grow in nature just fine around a ton of unclean stuff. I'm sure man/woman harvested them in some nasty forest, washed them or dusted them, ate and lived. You know what I mean? Nature doesn't use 91% alcohol on the logs it's growing from. People go harvest them from wooded areas and that's fine. No telling what bug or animal scales, fur etc are touching those logs they grow out from or the ground. IJS and curious. I want to grow some because local grocers do not have king or regular oyster mushrooms.

[@urbanfarm-it]

true! in nature, they don't have sterile conditions. However, as a result there is far more contamination and competition form other organisms. as our objective is to grow as efficiently as possible, clean environment for growth really helps to achieve that! Also, coffee grounds don't occur naturally in that form and have a really high energy and nitrogen content...this means that it attracts mould growth really easily if your mycelium isn't given the best shot by keeping conditions clean!

[@Pmomma100]

@@urbanfarm-it thank you for your reply. I am going to take a shot at it because God knows I love mushrooms, especially oyster mushrooms. And having to drive 1 hour just to find some and hope they have it in stock is bananas for me. Little things creep me out really easily and looking at how the mushrooms grow give me the willies but I'm willing to overlook all of that so I can have what I want. Lol Thank you again for your reply and educating me.

[@jacojoubert3464]

Did you have success? Contamination is really a big headache. Yes, nature doesn't use alcohol, but it also doesn't care if it grows where you want them to grow. It has a lot of space and will only grow where thei're conditions are met which is not necessarily where you want them to grow as is the case when trying to grow them yourself. Creating the conditions where they like to grow also creates conditions where many many other things like to grow which is what causes the problem.

[@JB_thebig3]

Can you sterilize the coffee for coffee stored over 24 hours?

[@urbanfarm-it]

Hi Bennie, although you can do that, and re-pasteurising is always better than nothing I would advice sticking to fresh coffee grounds wherever possible. some bacteria and spores are resistant to heat, so the older the coffee the more resilient their populations may be!

[@graham.broome]

is that just a trash bag?

[@buffalo369]

There is almost one roll of kitchen towels wasted. Not environment friendly, dude.
