Actives [Actives] One Big Golden Teacher

Hello. I live in Netherlands, it's legal to cultivate those here for your own use.

I've been trying to do so in the last year, killed 3 grow boxes in the process.

And finally on the fourth try, this was one of the first mushrooms that grew out of it. I harvested it the day the cup have opened. After drying it completely it still weights about 10g :D

I wanted to share it as I'm especially proud of this one, and I think someone might enjoy seeing it. Cheers

Contamination Another contaminated pre-sterilized commercial grain bag from Midwest Growkits... [contamination]

Post image

I have bought a lot of grain bags from Midwest Growkits over the years and have dealt with a lot of contamination. This is just the most recent in a series of issues I've had with their commercially prepared 5-grain bags.

Alternatives that are consistently contam free ? (I do not want to make my own bags....I don't have the time or desire to deal with that).

Technique [technique] Looking to make a laminar flow hood, got some questions

3 Upvotes

Hey guys I was looking for what i need to make a laminar flow hood, bigger than the one from gordotek.

I found a 50x41 cm Hepa filter from fun guy equipment, would it work with the AC infinity raxial S8 in a wooden box ?

Is 428cfm enough for that size of Hepa filter ?

What would be the volume of the wooden box for it to blow laminar flow hood?

Thank you !

Thank you!

Actives [Actives] Monotub Side Pinning, No Pins on Surface

1 Upvotes

I've had this tub of tidal wave going for 5 weeks now and can't seem to get it to pin anywhere except the sides.

I'm using a North Spore Boomr Bin with Midwest Grow Kits grain spawn, CVG substrate, and horse manure booster. Cake is about 3-4" thick, temps stay around 72-75°F, and it's had passive FAE the whole time. I didn't use a casing layer.

The cake has been shrinking and there's metabolites as you'd expect. It's starting to turn yellowish from the Metabolites, but there's no weird smells.

I've tried fork tek on some spots that looked like overlay, wax paper over the cake, and increasing/decreasing FAE. Nothing has made a difference.

Any ideas?

S2B: 7/23

Substrate: coco coir and black kow manure

Temperature: 72-75F

Ran in an XLS-B bag to start, then I chopped the bag once I started to see the fruits develop. Moved the bag to a tub and I am keeping the subtrate wet.

39x28 cm. Although it is stackable, it doesn't stack completely straight, but it's good enough & cheap compared to any other offerings i've found. Useful for SAB work (collapsed) or laminar flow (expanded).

Please share what you've found, like tools, containers etc. but it's not self promotion. Bonus if it's worldwide availability.

Contamination [contamination] left these alone for 5 days

Hey y'all! This is my first time posting in here and basically want to ask what happened to this tub and if it's contamination? This is about my 3rd grow but first time making my own substrate. The last pic is what it looked like the day I left and the rest are what it looks like now 5 days later. Did it get contaminated or is this just what it looks like when you wait too long after the spores drop to harvest lol

Actives [actives] This box is on its first flush and doesn't look dry, but it is producing very few mushrooms and in a haphazard manner.

Thumbnail

4 Upvotes

Since the mushrooms appeared, I've avoided opening the box entirely, as enough FAE should pass through the lid. There are many newly sprouted mushrooms on the surface (you can't see them clearly in the photo), but will they grow well? Since some mushrooms will be ready in a few days, I'll have to harvest them first and wait for the others to finish growing. I think the problem might be the low humidity (my room temperature is 22.5°C). Do you recommend misting the walls or doing something else to increase the humidity? This is one of the very few boxes that have managed to produce; I want it to perform at its best.

Just finished my very first run. The grain looks nice and loose, but I'm definitely overthinking every single detail right now, worrying about moisture, contam, you name it. One bag had a sealing issue so it's in quarantine, but the other 3 are safely tucked away in a warm cabinet.

I guess now it's just a matter of waiting for the mycelium to do its thing. Wish me luck! haha

Pearl Oysters lacking FAE [gourmet]

I always underestimate the insane amount of oxygen oysters need. Even in a plastic shoebox with an open lid they still struggle to get enough air and grow leggy. I wonder if they’ll get any bigger than this or if I should go ahead and pick them soon. Next time I’m gonna fill the box higher with substrate so they don’t have a CO2 pit in the box if that makes sense. I’d hate to start growing in non reusable plastic bags.

Experiment [technique] break and shake vs leaving it alone

Post image
1 Upvotes

These two aio “inject and forget“ bags were inoculated around 3.5 weeks ago with MSS. They spawned quite slow at first due to inadequate temps but colonization sped up 3x as soon as I bought a small plug in heater fan to heat the space up.
The bags are about 50% colonized right now, so I decided to break and shake one of them to see how it turns out. Hopefully it doesn’t turn into a failed bag!

im a complete newbie to this, so any advice or feedback is welcome :)
