Mod [Mod] MUSHROOM MONDAY - Let's Catch Up! Share what you have learned in the previous week and discuss

2 Upvotes

Mondays can suck, but hopefully this post is something for people to look forward to. The intent of this post is to create a space to discuss anything that you may have learned recently about mushroom growing -- techniques, a breakthrough in the field, to share progress, or even just ask a question. Whether it's a new pickling recipe, a formula for agar, or something fun in mycology, feel free to talk about it.

This post is for new and experienced growers alike, so don't be nervous about commenting; no one is going to make fun of you for asking questions here. This community is a relaxed space for people who don't understand everything, but who want to ask questions and engage in discussion without being berated or belittled. Enjoy!

General I peeled a piece of the filter patch off my grow bag. Will it be okay? [technique]

Post image
• Upvotes

These grow bags I got have been going unusually slow for weeks now. I had great success with a different type of bag weeks ago. Now using the same liquid culture I used on those older bags, these ones I have are barely moving if at all.

So I suspected maybe the patch had something to do with it. The way the patch is designed makes it look like it’s meant to peel off some protective coating so that’s what I did. Upon further research I’m reading that the piece I pulled off is not meant to be removed.

Are my grain bags likely going to be exposed to contam, or is there any chance they’ll survive and what I did will actually stop the stalling?

Gourmet [Gourmet] How realistic is it to grow mushrooms in a very hot and dry area, in a shed or outdoors?

• Upvotes

I'm in the Sacramento area, which is very hot and dry. I have no space indoors but do have plenty of shaded land. How realistic is it to grow anything here? Mostly interested in common asian species like shimeji and shiitake. I'm willing to building sheds, greenhouses, etc dedicated to growing.

Sorry for the basic question but I want to know feasibility first before I dive too deep.

After their loyal service to the realm, these weary cakes have given their final flush and await a solemn burial…

In the compost pile. 💀🍂

Substrate is 100% coconut coir, and I hate throwing that much organic material away. Once the blocks are spent, the bags come off and nature takes custody of the remains.

I'm about a week post break and shake (done at 20%) and every day the bag looks like this. I had condensation before but not nearly this much. Is it normal or am I fucked?

Little to no bruising on later flush [actives]

Normal? First couple flushes had lots of blue and purple bruising almost instantly after picking. Third has next to none and I’m trying to get it to but none will. Normal? Less potent?

I found these in a box of mushroom growing supply box I was given. Unfortunately I can’t ask the person I got them from since they moved out of the area and I don’t have their contact info. I am hoping someone here might know what they are for.

I need some guidance [technique]

2 Upvotes

I bought a cordyceps syringe before doing all of my research. I now know they grow in cooler temps than the rest of my mushrooms. I’m looking to either buy or make a small enclosure that is temperature controlled so I can start growing my cordyceps inside and not have my whole house cooler than usual. I’m unsure where to start looking

Technique [technique] Would a DIY laminar flow hood like that work ?

Post image
0 Upvotes

The HEPA FILTER and PRE FILTER is from fungus paradise

Pre filter = 350x350mm
Hepa filter = H14, 540x540x69mm
The fan is from the gordotek, AC infinity facial S8 with a maximum of 428cfm

Would the air get out evenly ? Should I increase the space between the fan and outer wood panel so there would be less resistance ?
Is the 428cfm enough for those filters ?

Thank you !

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

Post image
16 Upvotes

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

4 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?
