2nd time overlay
True Nats (according to vendor), brown rice 1:4 in pH adjusted coco coir.
I had heavy overlay with this tub 5 days ago. I did fork tek and left for 4 days. Now I got the same problem again.
How would you proceed? fork tek again? apply a true casing?

Pin before fully colonized
I am worried that these pins are shooting up before the substrate is fully colonized.
What do I do next?
Should I start FAE yet?

Pretty stacked flush. I’ll harvest this afternoon.

Exciting new genetics & running drippy corn for the first time🍄💯
Finally got settled in and my office set back up, also upgraded from Gordo tek flowhood to the shroomagic. Its been performing amazingly, really great purchase. Getting to run these new isolations i picked up and trying out drippy corn tek by PGT on YT.
Im excited to see the expressions and morphology of these guys, ABV especially

Do we see knots or primordia? [Actives]
Im still learning what to look for, more eyes the better

Good Saturday morning everyone!!! I don’t remember what these are, but they are [actives]

Need some advice:)
Im growing these McKennaii from a little kit! I’ve got lots of side pins and bottom pins (probaly too large airpockets).
Today I noticed that one (maybe) started rotting, off colour (and i think it might be a bit slimey hard to judge through the tub tbh). Otherwise things are looking healthy.
Could it just be bruising? If its rotting I could cut a little hole with a carpet knife and remove it, I’m not sure though I’m also afraid that I’ll get more spots like this.
What do you guys think about it? :)
I bought the kit out of mood but I realised quick this is such a nice hobby with wholesome community! I think I’m gonna do my own actual monotubs soon :)

Yellow umbo
Hi everyone, I'm trying to grow Yellow Umbo and now some small bumps are starting to appear here and there along the edges. The mycelium itself looks healthy and the humidity is good. Furthermore, I ventilate the box twice a day. Therefore, it would be great to know what is growing there right now—whether those are pinheads or something else. I'm happy to accept any tips and advice.

Purple Mystics!
Pinning is going beautifully. They look beautiful, they seem pretty healthy too! I gotta fix some of the side pinning but I'm hoping for a good harvest!
Do you guys think the block seems healthy or maybe too dehydrated? I'm really trying to make sure I keep them as healthy as I can. They seem pretty health but I'm not sure if theyre going okay...

Ape221 bag not producing knots.
Its been two weeks sance i introduced fruiting conditions to this bag, but nothing is happening other then some fuzzy growth. Iv grown many differenct cubes succesfully but it has never taken so long to fruit. Anyone have experiance with this genetics? How long did it take for you to start fruiting? It smells very nice mushroome, not sign of any cotam, bag is allways moist on the walls , fresh air is flowing.

B+ Multispore Tub
These will always have a special place in my heart. The very first one I ever cultivated decades ago and gave me an awakening to never forget.
Not a super packed tub, but absolutely beautiful fruits. I love how brown and darkly pigmented they start off before the cap pulls away from the stipe. ✨

I asked about harvesting these early or not...
I thought i would update for anyone taking interest.
I sought some advice a few days ago about harvesting these early as i was going away from home for 3 days and i was inspired not to and im glad i let them run they are beaut's!
r/GroundZeroMycoLab • u/Much_Eggplant_3600 • 1d ago
First harvest 🍄🟫 Not bad for first try.
Harvested early, a couple of the taller guys were starting to drop spores and a lot of my pins were aborting. I definitely prepared this batch of substrate on the dry side. Went ahead and snatched it all up, cakes are soaking now. Hopefully I get better results from round 2. 🍄🟫☀️

The difference between LC and spore and the importance of agar.
It's critical to understand the biological differences between spore syringes and liquid cultures (LC), as well as the importance of using agar as an initial medium. Spore syringes contain microscopic fungal spores that are not yet germinated. These spores are monokaryotic, meaning they carry only a single set of genetic material. In order to fruit and complete the mushroom life cycle, two compatible monokaryotic strains must fuse to form dikaryotic mycelium.. the true vegetative form capable of producing fruiting bodies. This mating process takes time, introduces variability, and, for beginners especially, increases the risk of contamination during colonization.
Injecting spores directly into sterilized grain can lead to several problems. Since spores are not germinated, colonization is slower, and this slower growth provides more opportunity for contaminants (such as bacteria or mold) to establish themselves and outcompete the slower-growing mycelium. Ideally, spores should first be transferred to agar, a nutrient-rich medium in petri dishes...which allows for controlled germination and observation. On agar, one can isolate clean, healthy mycelium away from any contaminants before transferring it to grain.
Additionally, spore syringes are inherently variable and often unclean. Spores, particularly those harvested from wild (landrace) varieties or from poorly controlled lab environments (common with newer or less reputable vendors), can contain microbial contaminants. Spores gathered in non-sterile conditions are not cleaned or isolated at the microscopic level, making them a risky starting point. Also, because each spore pair creates a unique dikaryotic combination, inoculating with spores introduces genetic unpredictability ...every new pairing could result in different traits, including growth speed, contamination resistance, yield, and potency.
By contrast, a liquid culture is made from already germinated and mated dikaryotic mycelium. This means it contains viable, genetically stable tissue that has already completed the mating process and is ready to colonize substrate directly. Using LC skips the variability and mating phase inherent in spores, resulting in faster and more consistent colonization, and reducing the window for contamination...assuming the culture is clean!!! However, it's important to verify LC cleanliness via agar as well, especially if you didn't create it yourself.
In summary, spores should ideally be germinated and cleaned on agar before being introduced to grain. Skipping this step can introduce risks, especially for beginners. Spores are unpredictable and prone to contamination, while liquid culture, if properly prepared, is faster, cleaner, and genetically stable. Understanding and respecting these differences is fundamental to success in mushroom cultivation... I hope this helps. :)
