Question How long until harvest
I have a few that have opened, but a good majority still havenât. Should I wait a few more hours / another day to harvest?

Iâll break this write-up into 4 posts. At the bottom of each post will be a summary in bold. You can find material lists in Part 2 and Part 3.

What most people know as âmushroomsâ are only the small reproductive part of the entire organism. Like an iceberg, most of the living tissue is actually found below the surface. When two microscopic mushroom spores meet in a pile of organic plant matter, they germinate and start producing mycelium. These microscopic threads begin forming a colony within the organic matter and absorb the available water and nutrients to produce an impressive mycelial network. After colonizing all the available nutrients, the mycelium turns its focus to reproduction.
To spread its spores, the mycelium forms into baby mushrooms, also known as pins. To produce these pins, the right fruiting conditions need to occur. Once the nutrients have been colonized and the mycelium reaches fresh air, the organism is ready for reproduction. The next rainstorm provides the moisture necessary, and the pins inflate upwards with the stored water into mature mushrooms.
Once mature, the mushrooms open their caps and drop their spores, withering away to ensure the success of their genetics.
To cultivate your own mushrooms, you need to replicate this process indoors.
Since this is still the most commonly broken rule and most commonly asked question:
You cannot discuss/advertise/promote vendors in r/unclebens. I want to keep it focused on cultivation, not a marketplace. If you need a recommended vendor, I recommend using syringes from SporeStock.com for USA and OrangutanTradingCo.com for UK. Every mushroom I've ever grown has come from these two vendors, and thousands of other users have had excellent success. No, I am not affiliated in any way with these guys, though I do think they kick ass. Yes, I am open to other vendor recommendations as well! I include this here so you can stop breaking the rules now.

Psilocybin is the nontoxic, non-addictive psychedelic compound found in âmagicâ mushrooms. There are more than 180 species of Psilocybin-producing mushrooms that grow across every continent. For 99% of hobbyists, the species to cultivate is Psilocybe cubensis, also known as "cubesâ. These are the easiest and most cultivated species of psilocybin mushrooms.
The sale of cubensis mushrooms is illegal across most of the world not because of the mushrooms being a controlled substance themselves, but because mature psychedelic mushrooms produce psilocybin. Psilocybin is the only thing mentioned in the Controlled Substances Act, because mushrooms arenât illegalâpsilocybin is. However, the spores of these mushrooms do not contain psilocybin and are legal to sell, purchase, and possess in most locations. In the US, only 3 unlucky states (California, Georgia, and Idaho) have specific laws preventing the sale or purchase of spores. Spores are sold in "multi spore syringes", which contain many thousand microscopic spores diluted in a sterile water syringe.
In the last few years, a better alternative to spores became available from many vendors online. Liquid Culture syringes contain live mycelium in sterile solution, similar to spores. Liquid Culture syringes are superior to spore syringes in almost every way, but have a more complicated history in a grey area of the law. More on Liquid Cultures later.
Either type of syringe can be purchased from vendors online. You can find several popular and legitimate vendors even on the first page of google, but as always, do your research before giving any vendor your money. My personally trusted vendors are recommended in this guide, since itâs the most commonly asked question.
Some countries/states/counties/individual cities have finally approved legislation to allow the cultivation or possession of small personal amounts of psilocybin mushrooms. In many places across Canada and the US, local law enforcement has made prosecuting psilocybin-related arrests their lowest priority after evidence has pointed to no increase in crime related to psilocybin decriminalization, as well as the immense therapeutic and antidepressant benefits psilocybin studies have shown. Make sure to check with the jurisdiction of your area before attempting cultivation of any cubensis mushroom.

Once you have your syringes, you need to inject your spores or Liquid Culture into hydrated and nutrient-rich grains to produce your mycelium. This step is known as inoculation and is followed by colonization. When your grains are colonized, we call them Spawn Grain.


You can buy premade, ready-to-inoculate grain from the store in the form of Ready Rice (more on this in Part 2), or you can make your own DIY Jars of spawn grain. You can inoculate nearly any hydrated and sterilized grain, including Brown Rice, Whole Oats, Millet, Rye Berries, Wild Bird Seed, Corn⌠you name it. But there's one major problem:

Mycelium's requirements of water, nutrients, and warmth are all the perfect breeding ground for mold, mildew, and bacteria. These contaminants live on our skin, on our surfaces, and even in the air we breathe. Normally itâs not a problem to our immune system, but the largest obstacle in mushroom cultivation is contamination, and it will ruin an entire grow and needs to be avoided at all costs. So, you need to make sure that your grains are hydrated, warm, and EXTREMELY sterile.

As covered in Part 3, the basics of spawning to bulk are simple:
First, your spawn grains need to be 100% fully colonized. Then, you will need to mix your grains into a bulk substrate. After the mycelium has reconnected with itself in the new substrate, you need to introduce Fruiting Conditions. This involves simulating fresh air, rain, and a little bit of sunlight. Within a few days, a Flush (or group) of mushrooms will grow from your colonized surface. Once you grow your first flush, you can then harvest and dehydrate your mushrooms, and feel proud for accomplishing something incredibly rewarding.

And that's the basics of cultivation. If this information seemed overwhelming, hang in there as I simplify and break it all down in the following guide. If you still have doubts**, I promise that you can do this**. The original cultivation guide I posted on Reddit years ago has received more than a thousand awards, helping hundreds of thousands of beginners cultivate, while catching the attention of the mushroom industry as well as mainstream media. Every week we see countless beginners post their harvested results here in r/unclebens. If they can do it, so can you. So, grab a pen and a pad for some notes, and learn everything you need to know about cultivating mushrooms from start to finish.
It just might be one of the most important decisions you make in your life.
Your first step in cultivation is to obtain either a few spore syringes or a few liquid culture syringes from a reputable vendor. My personal recommendations can be found in Part 2. Vendors cannot legally advertise or sell syringes specifically for use in cultivation. Syringes are usually marketed for âmicroscopyâ, âtaxonomyâ, or âresearch purposesâ. If you ever have an issue with a syringe, make sure to avoid mentioning cultivation to your vendor so you arenât refused service.
An average spore or Liquid Culture syringe is 10 to 12mL, (mL and cc are used interchangeably) and should come with a separate needle in a sterile package. This sterile needle will be used during the inoculation process and shouldnât be opened until then.Â
Pros:
¡ Spore syringes are guaranteed to be legal to purchase, sell, and possess in most places across the world (with 3 US state exceptions: CA, GA, ID).
¡ Spores can also be stored in a fridge for years, sometimes longer than a decade, and still be viable.
Cons:
¡ Spores take a while to germinate, so colonization can take weeks or even months.
¡ Spores frequently arrive already contaminated by the vendor. This is due to how mushroom spores are harvested, which is nearly impossible to guarantee contamination-free syringes. No matter how meticulous the harvesting process is, most spore syringes cannot be guaranteed to be sterile.
¡ The thousands of competing spores in one syringe also result in randomized genetics. The spores of a parent mushroom might grow children mushrooms that neither look nor grow anything like the parent generationâsometimes even worse than the parent generation.
Notes: Each spore syringe will contain thousands of dark microscopic spores. Individual spores are not visible to the human eye, so if you can see them, youâre actually seeing a large clump of the spores themselves. It would only take 1 drop of spore solution from these syringes to begin colonizing your grain.
Â
Pros:
¡ Liquid Cultures can have guaranteed sterility if made correctly, leading to fewer contaminated results.
¡ Since the mycelium is already germinated, LC colonizes grain significantly faster than spores.
¡ LC can have guaranteed genetics by skipping the randomized spore phase.
Cons:
¡ LC can still be contaminated by the vendor, though far less likely than with spore syringes.
¡ LC stays viable for only 6-18 months in the fridge, as opposed to spores which can stay viable for many years if stored in a fridge.
¡ Potential legal âgrey areaâ.
 In recent years vendors began selling Liquid Culture syringes to the public, often under the name of âisolatedâ syringes, or just âSyringesâ (without âsporeâ included), or even openly advertising their syringes as liquid cultures.
For decades, it was scientifically proven that mycelium grown on solid grain contained psilocybin. This made most cultivators believe that Liquid Culture syringes, which contain early-stage mycelium suspended in solution, must contain psilocybin, and were therefore considered a illegal to purchase or sell, similar to the mushrooms themselves.Â
What gave vendors confidence to begin selling Liquid Cultures was the results from new studies that showed the development of psilocybin and psilocin only starts during the later stage of mycelial growth. These results showed that early-stage mycelium suspended in solution DOES NOT contain psilocybin or psilocin. Following these studies, vendors began sending their syringes to laboratories for âHigh-Performance Liquid Chromatography and UV Analysisâ to determine if there was any psilocybin present at all. Which, by the standards set by the DEA themselves, means that these syringes would be legal to sell, purchase, and possess no differently than spores.Â
Out of curiosity, I sent in some Liquid Culture syringes I bought to a lab providing these tests and received the same results: no psilocybin present in my LC syringes.
I prefer using liquid cultures unless doing genetic work when starting from spores. Ultimately, itâs up to you to determine the best syringe type for you to get started.
Â

Note: The difference between âstrainâ and âvarietyâ doesnât have a true scientific mycological definition, and while âvarietyâ is likely appropriate for spore syringes, âstrainâ is likely more appropriate for LC and is commonly used interchangeably. Therefore, I will simply use âstrainâ as the phrase to use here to reference the type of cubensis mushroom (sorry hardcore mycology buffs).
Â
There are an overwhelming number of cubensis mushroom strains out there to choose from, so let me simplify things:
Psilocybin mushrooms and psilocybin itself, are not like cannabis, or other nature-produced psychoactive compounds**.** When it comes to cannabis, different strains contain different combinations of 4 types of psychoactive THCs, multiple CBDs, and more than 80 cannabidiol compounds that change the psychoactive effects. When it comes to psilocybin mushrooms, the active compounds are actually much simpler. There are only two scientifically confirmed psychoactive compounds present in cubensis mushrooms: psilocybin and psilocin. Although psilocybin is the famous compound, itâs not the actual psychedelic drug. Psilocybin is only a âprodrugâ for psilocin, and once ingested is converted into psilocin in the body.
Note: While OTHER potentially psychoactive compounds such as baeocystin HAVE been discovered in varying amounts across different strains of cubensis mushrooms, they are almost negligible in concentration and have not been confirmed to have physiological or psychoactive effects. For now, itâs safe to assume that the only compounds to care about in cubensis mushrooms are psilocybin and psilocin.
Although some vendors might claim that one strain provides a different experience than another, the difference between strains is only cultivation-based or appearance-based. Scientific studies have generally confirmed that the psychological effects produced from consuming one cubensis mushroom strain are not majorly different than another. Unfortunately, recreational drug culture has spread a lot of misinformation regarding mushroom strains**.** In our upcoming âMushrooms for the Mind Therapeutic Use Guideâ focusing on safe use, harm reduction, and education regarding psilocybin, youâll learn that your preparation, mindset, and setting have everything to do with your experience, regardless of what strain you choose.

However, there is one real factor to consider between strains: potency. The concentration of psilocybin and psilocin determines the potency of the experience. Although all cubensis mushrooms contain these compounds, it is 100% Â true that different strains express different potencies. The one exception to this rule could be Psilocybe natalensis (aka âNatalensisâ, or âNatsâ), which is a newly discovered cousin-species to cubensis. Many reports show that this cousin species to cubensis potentially provides slightly different physiological and psychoactive effects, but more evidence is needed before that claim is considered fact.
Most strains exhibit âstandardâ potency, such as Golden Teacher, B+, Mazatapec, Z-Strain, Cambodian, and similar varieties. When grown next to each other, many of these mushrooms would be hard to tell apart and are more likely marketing and advertising labels than truly different mushrooms. There are a few known potent strains, including Penis Envy, Albino Penis Envy (aka APE), Enigma, Tidal Wave, and other mutants. These mutated strains are often more difficult to cultivate than standard cubensis and require more time and care, so I donât recommend starting cultivation with any of these.
My recommendation? Give B+ or Golden Teachers a try. They are known to be hardy, fast-colonizing, and are the most popular strains for a reason. However, the phrase âa cube is a cubeâ is appropriate for most cubensis strains, since there is so little difference. Pick one and just go with it.
For your first attempt at cultivation and to give yourself the best chance against contamination possible, Iâd recommend purchasing two to three different strains of syringes from a reputable vendor. Syringes should cost about $20-$25 USD before shipping. If you donât use all your syringes for inoculation, you can store them in a fridge, where Liquid Culture syringes will last for 6-18 months, and spore syringes for years at a time. One 10mL syringe can be used to inoculate 10 to 20 bags of ready rice or more, or about 10 quart-sized jars.

r/unclebens • u/rainydays_rainyways • 13h ago
Left for work and had picture 1 (I harvested the largest one) came home 12 hours later to picture 2. Harvested all of them and theyâre now in the oven dehydrating.
They dropped a ton of spores, will they be okay to attempt a second flush?
r/unclebens • u/Kbreezy20 • 13h ago
And thank you to this awesome community. My first ever grow and Iâve learned so much over these past few months. Have 4 more bins fruiting and should yield over 100g dry from first flush. Had my first trip with 3.5g OJ Tek and I was a freaking cosmonaut!
r/unclebens • u/jess-birdman • 7h ago
I have been active here especially and other subs 5 years ago when I grew mushrooms!
I usually learnt from this sub and PhillyGoldenTeacher.
I would like to start to grow again.
Would like to ask, did anything changed on formulas, recipes , procedures to make it easer and more effective since then?
Or all the same?

NSS, first flush, 2lb grow bag, got roughly 13g dried. Took about 2 months. Pretty excited!
r/unclebens • u/Traditional_Dare_218 • 11h ago
Before I went out of town there were only pins, when I got back it was time to harvest! I wish I had taken a picture of the box before harvest, these are hillbillies! My other box I harvested right before I left (golden teachers) but they seem to need a few more hours in the dehydrator so Iâm leaving these in front of the fan. Will they be fine like this for the 12 hours or so itâll take to finish my other mushrooms?

Enable HLS to view with audio, or disable this notification
Was never supposed to take off the lid but accidentally knocked it whilst opening vents for FAE, some water did drop from the lid onto the sub

I just noticed this little pin popped up and itâs my first time. Should I top it with a layer of coco coir now or leave it be?
r/unclebens • u/SnooDoodles8906 • 3m ago
Can someone who knows a thing or two tell me if I buy liquid culture and grow bags under the same name am I gonna be on some watchlist? I really want to grow I am just afraid to get some feds knocking on my door some day.
r/unclebens • u/elijemm • 6h ago
No SAB, just hopes and dreams. 9 dayâs into inoculation 2/3 bags survive, I pour the grains that are about 30% colonized into a quart sized ziplock bag and b&s in hopes it would colonize faster, the FAE hole, if I can even call it that took way too much time for the first baggy so I decided to not make an FAE hole, for the second one. 4 days later I come back to both bags fairly colonized with the ziplock with active FAE being almost 100% colonized and the non fae bag 80%. what I think was this means is with ziplocks you can disperse the mycelium easier and the air that made contact with the grain during transfer from UB to ziplock was enough stimulation to make the mycelium grow.

Thank you everyone for your comments on my last post! I really appreciate all the feedback and knowledge everyone has been so kind to pass on to me.
To answer some questions and give feedback to everyone's suggestions is the following:
⢠The strain I am growing are Jedi Mind fucks. It is the only strain I have grown previously so I felt it would be in my best interest to stick to this while I am scaling up as it's what I 'know' the best.
⢠I have been told by a friend that the best way to introduce FAE was with the fans blasting air through my filters and it had worked with the small monotub previously. However now after seeing your guys suggestions I have changed from 3 fans blasting directing through the filters, to one ocelating fan positioned on the other side of the room for more passive FAE.
⢠I used millet grain bags and left them to fully colonise before adding them to my CVG. I used a 1:1 ratio for bags of millet and bags of cvg. X2 of each in my bigger tub and x1 of each in the smaller tubs.
⢠I have also lifted the tubs off the floor to prevent contamination from the carpet which is something I definitely didn't think about before!
I have included a few pictures of my current setup after improvements as well as what my sub is looking like as of today. If anyone has any more advice or thinks they know how to improve my setup/chances of a successful run then I am more than open to hearing suggestions.
Finally, please could you guys take a look at my cake and see if it still looks like I am on the right track or if it's best I start again? I have had some mixed opinions so I'd just like to see what the majority thinks. I am also extremely colour blind so I don't trust my eyes as much as I'd probably trust yours. I know purple/green = bad and white = good. I can see some patches I would say are sort of yellow but I'm not sure if that's just the grain I can see through the mycelium or if it's contamination.
Thank you guys for all your support and feedback. You truly are a great community of people and have made me feel very welcomed and gave me great advice, especially since I never post on any forums ect.
Many thanks and much love!

Hi,
Nothing from this aio bag after nearly three weeks. Temps have been stable but no pins. More fae or humidity?
Mush love
r/unclebens • u/Soggy-Feature-68 • 6h ago
Think thi would work good for mono tub Minnie batches
r/unclebens • u/Mathbound314 • 3h ago
After my grain was fully cultivated I did a break and shake, but some of my cultivated grain ended up on top of the substrate. Right now the substrate isn't fully cultivated and I haven't opened the bag or exposed it to sunlight, it's in my closet. I see a few things growing on top that I'm guessing are mushrooms fruiting, the one I circled is over an inch in length. I'm worried if I open the bag it will become contaminated because the substrate isn't fully cultivated, only like 85% is. Do I need to open it and mist the sides with water to continue fruiting?
r/unclebens • u/scvmfvckfl0w3rb0i • 9h ago
So proud of the progress because it has been a very long journey so far.
r/unclebens • u/Individual_Tell_3183 • 3h ago
Iâm a relatively novice grower here with about a year of growing under my belt. Iâve had successes and failures. Iâve started making my own aio dung based bags using dry aged horse manure, rye grains, coir, vermiculite and hay. Since starting to make my own bags though I cannot for the life of me successfully fruit them. Theyâve colonized incredibly well, but Iâve got 3 bags that have been in fruiting conditions for about 6 weeks with no pins. Iâm about to open 3 more and Iâm just wondering if my technique for fruiting needs to be different for dung based bags rather than cvg. I think Iâve been suffering from overlay due to excess nutrients and the mycelium being too happy colonizing. (Growing ghost, PE, and natal ss) If anyone else has had consistent success fruiting dung based aio bags, please help!
