My mycelium has started going green and its got beads of something on the top, have I left it in my agar tray to long? Or does anyone know what else could have happened

Hello!

This is my very first post as I am quite new around here. I've been digging around and it seems great to see all the stuff people share...

I'd love to poke your experienced brains to see if my initial tests with grain spawn are running smooth. I made about 14 jars of 490ml or 16oz so far, in two separate batches, all properly pressured cooked and inoculated with Reishi:

• 7 jars only with Rye
• 7 jars with rye and a spoon of ground coffee and barley malt (somewhere I read it was good, so I felt like testing and potentially compare).

I inoculated the jars about 10 days ago with 1cc each. I have them in a closed box over a heating mat for plant (not touching but barely one inch apart) set to 26C or 78F. While the growth of the mycelium seems on its way, it also seem slow for 10 days.

How quick should one expect to see a jar colonized?

Also, I wonder if its the temperature but as you can see in the image on the right side the rye looks rather dry and with hyphae. on the left side, it looks quite wet altough prior to the inoculation, I let the exterior moisture on the rye to dry... so don't really know why this humidity/condensation showed up.

Would that be an obstacle to the colonization? Just in case I gave all jars a nice shake today.

Grain Spawn

I teach in a makerspace classroom and I'm doing a mycelium project with my 7th grade students. Our school has a plant sale in the spring so we're making containers for the seedling plants out of mycelium I cultivated from liquid cultures. I used to use growbio GIY materials but now have learned to grow my own spawn and use materials at hand for substrate. So this project has brown rice spawn with reishi cultures, then grown in shredded cardboard with some coffee grounds added. The kids made the containers by pressing the mixure into large yogurt containers. We had great results, no mold even with kids and their germs. Here they are drying on my boiler.

I started these jars on Saturday and they don’t look like they did last time that picture is after shaking up before shaking up it’s all directly on the bottom of the jar

This is only my second time doing this so I honestly barely have a clue what I’m looking for

Any help or advice would be greatly appreciated 🙏🙏

Hey I was wondering if anyone had any data on the youngs modulus of mycelium bricks, does it differ between strains and substrate? Any data you have would be welcome thanks 👍

I sterilized some hay and sawdust about 5 days ago and had a couple of bags left over 2-3lb each. I’ve left them out in the grow room not sealed. They’re not showing signs of mold rn but I want to make more substrate and not waste.

Can I put those bags back in the pressure cooker? Maybe transfer to new bags and re sterilize or is there no telling. I have some oysters going off very well in the grow room right now.

Hi, any idea what to use for drying a 2x1m, 7cm tall piece? Aside from industrial walk-in ovens and so on..

Hi, let me know if one can hook me up with guy who has spore syringe for b1 varient. DM me or reply

I’m trying to make a mycelium block that is fire retardant what substrate and strain can I use to be the most effective?

Hi I have colonized a soil, sawdust and wood chips substrate with morel mycelium which grows OK. But all of a sudden this fast-growing white mycelium is growing over it. What is it? It seems to love the moisture on the sides of the tub????

Hello everyone! I have a question which is related to my project about the use of mycelium as geotextile.

I just want to know whether these innovative mycelium fabrics will somehow activate or grow again when buried in soil? Because I have read some articles telling that the mycelium in these fabrics are already "dead" and I don't know what can happen with "dead" mycelium.

Thank you everyone and have a great day!

Hi guys, just want to share my attempt on using mycelium for sand improvement. It makes the sand stiffer and hydrophobic. Has anyone did the same? Maybe if you guys has tips to grow it on sand faster? Thanks before

Hi guys! I'm new here, but I really need some advice from people around here.

I'm part of a University of Queensland backed start-up trying to repurpose spent coffee grounds into a myco-composite that can be used to replace plastic packaging.

I would really appreciate any feedback on the tech, anyone with experience in the field or any of your opinions!

I need to grow long white spindly mold on a cherry for a movie prop. I can see the mold in my mind’s eye, but don’t know what it’s called or how to get a sample to infect my cherry with.

It looks like long white, almost transparent hairs. What is it called?

How to make mycelium composite homogenous? What is the secret to grow mycelium evenly throughout the substrate, (inside out) so that the dried product can be postprocessed, for example cnc milled?I tried to shake and mix the substrate when sclerotium showed up, but no luck still.i am using ganoderma multipileum

[general] I started to try agar and honestly thought it would suck but I love it. All of it but have big problem. I'm not sure if I'm heating water up to fast but I can't get it clear all the time. Any suggestions? I use LME and agar powder. Use 7g LME and 10 agar for 500 water.

Hi everyone, first time growing and I need some help
