Fruiting advice? (green contams)
    #22120645 - 08/21/15 03:38 AM (8 years, 5 months ago)

I am getting increasingly frustrated. My last attempt was a complete and utter failure. The incubation went perfectly but when it came down to fruiting they all got green mold and stopped producing mushrooms halfway through the first flush. With the first attempt I used the shotgun tek with the cakes on foil in my closet propped on top of shot glasses and on other tubs to keep the FAE good and off the floor.

I figured the problem was that my closet was 95 degrees and it was doomed to mold as a result. For THIS attempt I am using a homemade swamp cooler until I move into my new place and I have successfully been able to keep the room at 70-75 degrees. I have a hepa filter and fan which also seemed to lower the temp in the room. I follow all the proper sterile procedures. mask,shower cap,gloves and lysol before entering the room and/or handling the cakes....yet i STILL HAVE CONTAMS. What makes even less sense...is two of the jars that i thought had contams early on I placed in their own small tub and just stabbed the tub with a knife to give it a little more air and placed it in another room. A fairly dirty room with high heat/humidity. I have only handled the cake with my hands and taken no precautions yet these seem to be pinning faster without any problems. I dont get it at all. I am wondering if the shotgun tek is whats flawed because I have no idea what i could possible be doing wrong. I cant afford for this to keep happening. the cost of this project adds up fast.

I have included pictures. the small tub and cakes are the ones in the other room...the other pictures are of my setup and the the arrows on the cake pic are pointing to discoloration that is hard to see but in person it looks green. I'm hoping I figure out what is going wrong soon but, as far as trial and error goes, i cant make improvements if I dont know where i'm fucking up in the first place. If I need to make a post with step..by..step descriptions of everything I have done I will. I have since moved the 5/17 cakes that have that discoloration to the monotub on the left. still have 12 with no signs yet...though this is only 3 days into the fruiting stage.

The bluing near the arrows is bruising from you handling the cakes. 95F is definitely way too hot to fruit/colonize in. I'd never go above 80F and try and keep mine at a constant 70F or so.

You shouldn't have any fan in a room with a SGFC as it will dry out your cakes. I'd get rid of that and try and cool the room another way.

The other tub you have looks really small as well. You should try and have a neater area in your SGFC. I suspect covering the perlite with verm will block it and disrupt FAE from the bottom.

The cakes look super dry. How often are you misting and fanning?

I appreciate the reply. Though those spots aren't blue..they are a green tint. I don't even think I handled those much before I saw the discoloration. I live in Arizona and my apartments are shit. I didn't know til it was too late that they don't have a proper AC unit. I have no other way to cool the room. The most I can do is move the fan as far away as possible. I am misting 3 times a day but I can increase that to compensate. I really appreciate the input...still worried about the discoloration though. As far as the smaller tub...it's in a different room with because I thought it had contams. Only put them in a tub in the hopes of getting something out of them at least

hard to say from the picture. normally trich (green foresat mold) won't grow on a newly birthed cake as there's no place for it to grow (the healthy mycelium isn't a good place for it to grow) however the pics do look a little suspect...

can you get another picture that's less blurry? put the cake down and try and steady the camera as much as possible?

does it look like this?

no...and honestly the color does look a little blue to me now...and the cakes that have the discoloration are deepening in color so i suppose bruising would make sense. the only thing I can think of is that when I birthed them they didn't just pop out..i had to bag the jars on the counter....unless there is some other magical way of getting the cakes out then that will continue to happen. the only issue I have is that this happened last time too...and the cakes continued to get dark and then started to grow visible mold. I just assumed this was the same shit. here is a better pic for you though. :p

Though I am a little worried about the humidity...even before the fan was put in the room the shotgun tub didn't seem to be doing anything. I would expect humidity would mean there would be condensation on the sides and there is never so much as a drop. Now I'm wondering if I should just say fuck it..and put tape over all the holes. Maybe the real reason my last group of cakes stopped producing shrooms was because they dried out

humidity on the sides of the box doesn't mean the humidity is there. it usually shows a temperature difference between the inside and outside of the box
a properly working SGFC doesn't have condensation on it. humidity is important, but not as important as Fresh Air Exchange, so DON'T tape up the holes


as long as you have 1/4" holes on all sides (including the bottom,  infact, especially the bottom, they allow the air to rise up through the damp perlite, gain humidity and pass on the benefits to the mushrooms)

don't tape it up, get rid of the tin foil tray underneath your SGFC, take a few deep breaths and believe that you will get joy at some point

I did the tinfoil because my last setup molded..figured I'd change it a little for the hell of it I guess. But yea I'll do that immediately. Thank you for the info. :smile:

temps are too high, if your place stays around 70 to 80 i would recommend getting rid of the heat source, it will just add to your frustration and care for your cakes as high temps  make it a perfect breeding ground for contams, also can dry your cakes out and cause them to bruise , the pic of the discoloration i believe is bruising from either handling the to much, misting them with a globby mister or from being to dry. with those heaters and high temps i believe that is the main suspect. start there. and i would make a lil bigger holes in that one fc as they look uneven in size, clean the holes up and that will help with fae. best of luck to ya.

My apartment is that hot because I live in the desert. I am keeping the closet at 70-75 with a homemade swamp cooler. I can't possibly fix the tubs right now with all those cakes in them. Might have to do that next to round though

The bigger the room it's in the better. A closet is never enough fae. Also did I read that right? You have a fan going? No fans for a sgfc! When your shit is dry, it isn't a humidity problem. It means you need to be misting more. Keep them glistening wet. Make sure it has those crystal glistles. Stick your finger in the perlite. Make sure it's damp. Is it raised off the ground? How deep's the perlite?

I have no choice but to have a fan and have it in a small room. My apartment is really fucking hot lol...the fan is facing The ground and ice to cool The room though The perlite is about 4 inches deep and the bins are propped up an,inch off bins underneath them..about 4 feet off the floor

I like them raised at least 6 inches off the surface under them. You don't want anything that could hinder how much air gets pulled in or out. Also 80F for fruiting is perfectly safe. For colonization it's crap. But for fruiting high temps aren't such a big deal.

Your SGFC is way to small, it cannot function properly and that's why your cakes are suffering. Go get yourself atleast a 66 quart tub and make sure there's 5+ inches of perlite and holes every 2 inches. I've seen some 30 quart sgfcs on here but they aren't ideal. You want 12-16 inches above the perlite. Those 8quarts make okay trays and dubtubs but not sgfcs.

What exactly does high temps for incubation cause to happen? Mold? Slow growth?..

And that kinda makes sense. A bigger tub with more perlite...course I can't do that now. Kinda too late. I'll just have to wait til I fruit my other 40 jars I have incubating

Bacteria thrives in hither temps, lowering your BE as well as increasing chances of early contams during fruiting. Also colonizing myc slows down after 80F.

Honestly the fc might not be ideal, but it really doesn't matter. Just keep them glistening through misting. That's the thing they need. If you can keep them glistening 24/7 through misting, you don't even a fc in under 10% humidity(another Open air grow). All problems of being dry are always from the grower not misting enough.

Also did you make sure the perlites wet? Are you misting the perlite thoroughly at least once a day?

It's not too late, I think those cakes would flush well in a proper sgfc, being misted and fanned twice a day.

I disagree with misting being the key factor here. The mycelium needs evaporation from the surface of the substrate as a pinning trigger.

In an open air grow, especially with 10% humidity, there will be constant evaporation, so constant misting is necessary. I think cakes can be over misted, especially in a cramped fc where humidity is remaining high. Too high of humidity will retard evaporation and result in a weaker flush.
