Blue Mycelium Throughout Bulk Trays
    #22155586 - 08/28/15 09:38 AM (8 years, 5 months ago)

Hi!

This is my first bulk grow attempt (and second overall). I tried Googling and searching the forum specifically for "blue bulk tray" and "blue bulk substrate" but didn't seem to get anything particularly helpful; every post with pictures seemed to look *much* better than my present situation.

Details of the bulk grow are as follows:


  • MS P. cubensis "Golden Teacher"
  • 1 quart rye berry spawn
  • Bulk substrate: Damion5050's Elementary Coir tek
  • 1:1 spawn ratio
  • 8 days to full colonization of bulk substrate
  • Uncased
  • 13"x13"x9"(lxbxh) SGFC


When initially placed into my SGFC, the trays were covered with a layer of pure white mycelium. Since Day 3 or so, however, the surface has been blue like this:



Given the information provided, would anyone have ideas as to why this could be happening? It's now Day 9 of fruiting and the pin-set looks pretty sparse; even more so on the tray which is visibly bluer.

One theory I had is that the bulk substrate was not sufficiently wet when prepared. I followed Damion5050's tek to the letter, but only later learned that "field capacity" bulk substrate should produce a light stream of water when squeezed - mine was definitely well below this moisture level.

Thanks in advance for the help!

Some of those caps have growth on them I haven't seen before, what do those tan areas feel like? Sometimes bacteria in the substrate can cause strange growths, but I haven't seen it on fruit.

Mycelium turning blue is due to stress, the most common of which is dryness. It looks like somethin else might be going on though, the substrate looks yellow like the myc has been releasing metabolites to fight off bacteria.
Has it been yellow like that since colonized? Or at some point were there noticeable droplets of yellow emerging?

In the first picture it looks like there's a wall very close to the wall of your SGFC, for proper air flow you really want it 1 ft away from walls and lifted off the ground.

Thanks for the reply, Appalachian Brony!

I noticed the weird caps too. They seem to be only growing out near a specific spot. Oddly enough, the stems and the stem-colored growths on the caps turn blue when misted, then quickly recover within about 30 minutes. This only* happens on the mutated shrooms.

The tan (it's more bruising-blue in person; my camera seems to make it look browner than it is) areas feel spongy and don't leave a noticeable residue on the fingers after being touched.

I've attached a close-up image of the mutated caps for your reference.



Thanks!

It's probably some variation of improper conditions.

The blue is bruising from being dry.

Right on man, judging by that picture your only issue is dryness. I would try to selectively mist the substrate real well over the next few days. As soon as you harvest you can dunk those trays and be good to go for the second flush :thumbup:

I agree with tagyo, the mutations are probably environmental. Does your SGFC got space away from walls?

Thanks again for your help, taGyo and Appalachian Brony!

taGyo: I remembered your advice not to mist so much from my last thread, and the stems are indeed looking a lot better. Thank you!

Yeah, I suspect the initial dryness of the substrate is playing a big part in what's happening now. I'll try to get the substrate on my next grow closer to field capacity without varying anything else and see how it goes. I now have 6 quarts of this MS cube' on rye and 2 of an MS Panaeolus cyanescens ready to go, so I have lots of material to experiment with.

The SGFC is more than a foot away from the nearest wall (I moved it to get a good shot and for... privacy reasons), but I'm only elevating it 3" above the desk I've placed it on. I also understand that the FC I've got right now is a little small. It was the most suitable thing that I could find when I was IKEA, but I've since acquired this monster, and can't wait to break it in :cool:



Thanks for sharing your experience and insights!

It's almost hard to most too much. Give them a good soaking a few times a day.


--------------------
Stop experimenting half way through your first grow. Grow it to maturity, watch it, learn from it. Do this a few times then experiment with different ideas and figure out what works best for you.

That's whats up, I still think once you dunk those they're gonna ball out on the next flush.

That new tote looks dope, I gotta say though if you know how to spawn to bulk you are ready to run a monotub. It's easier, more efficient, and yields better.

Instead of spending 20 minutes drilling 100+ holes you can spend a couple minutes measuring, and a couple more drilling out 6 holes.

When I did a coir tray with 1 quart of spawn, cased it, and fruited in an SGFC I got a quarter oz 1st flush.

Then I read pasty's thread about minimonos and decided to give them a go using 2 quarts of spawn an a half brick of coir each. No first flush was under a zip. Using damion5050s tek makes the perfect amount for two 30ish quart minimonos (mine are 31, pasty's are 27 I think) at 3.5 inch sub depth. These a couple first flushes from MS, uncased.

Thanks for the advice, Appalachian Brony and tahoe :mushroom2:

Here's an update on the trays. They're looking a little better now:


Those mutated mushrooms, though...


There's also this spot of disconcertingly dark mycelium right next to the mutant cluster:



I have no idea what's causing this. It looks like some kind of blight, or shroom cancer, or something.

I think the larger specimens should be ready to go in about 24h or less. Fingers crossed that the veils won't tear while I'm at work.

Also, thanks for the visual comparison of the monotub vs. bulk trays in an SGFC. I'll definitely give the mini-mono method a go, since it looks to have yielded a lot more with less effort.

Hopefully the GF won't mind her manicure scissors being appropriated... I'll try not to scorch them too much  :iloveyou:

It all just looks like bruising from being too dry for too long. Keep up the misting.
