Telltale signs of grow chamber deficiencies/saturations? (FAE, RH, etc) * 1
    #15614029 - 01/04/12 07:02 AM (12 years, 1 month ago)

Hi guys. I've been reading up on the forums for a few months now and have managed to get a few decent grows under my belt using mono-tubs and coir.  I've read here and there about how you can tell your grow environment is lacking in areas such as FAE, RH, lighting, and things like that, but I've yet to find some truly great examples or explanations of such "telltale signs".  Here is a quote from HorizonSpawn that I've saved that should give you an idea of what I'm looking for here: "More FAE will give you shorter fatter fruits; whereas high CO2 will give you tall skinny fruits...  More light will give you better larger cap development; whereas minimal light will give you smaller caps..."

If some of you experienced growers could elaborate for me on the quintessential growth parameters--and more importantly how I can tell if my micro-climates are lacking or over-saturated in such regards--it would be much appreciated.  Pictures would be even better, but I'm not asking anyone to write me an article.

I know that such information is no doubt available via the search function, but it seams to be all spread out through this huge knowledge base of ours, and I'd like to start a thread that can put it all in one place.

Thanks guys!

The below quote is from the OP of this thread.

- Troubleshoot the fruit!  :cuddles:  Effect! Cause! Solution!

While the effects and solutions are of greater concern with regard to troubleshooting, I would truly appreciate confirmation/correction about the causes since I do not know the complete science involved. **Consider my "causes" educated guesses.**
In no particular order...

1.
Effect: "Fuzzy-feet" or fluffy stems happen when the mycelium seems to crawl up and surround the lower portions of the mushroom and even sometimes up to 50-60% of the stipe. It's not widely considered aesthetically pleasing, and it's one more thing to clean up after harvest. It won't harm you to eat it, but the chemical content is comparatively low.
Cause: (Edited per RR's chime in.) Stagnant or still air in the fruiting chamber is our culprit here.
Solution: More FAE is the easy fix. :thumbup:

2.
Effect: Prematurely opening or small caps and/or small mushrooms in general.
Cause: It is possible that with MS projects genetics have opted for small fruits, but more often this is a result of insufficient lighting or improper moisture content. I write improper because too much and too little water can dwarf our fruits. However, if we have too much water in the substrate, the mushrooms should look excessively glossy/slimy on the caps. Usually, though, too much water results in anaerobic contamination before we see a flush. For those of you who attribute a short substrate depth to small mushrooms, here's one for you. :tongue2:

The reason deeper substrates support larger flushes and fruits is because larger substrates hold more moisture.  If you give proper moisture control to small substrates, they will perform well too.

Solution: Check the light cycle and bulb rating. Be sure to have as close to 6500K as possible (mine is 5500K and it's fine) and perhaps buy a timer set to 10-14 hours on/14-10 hours off. If the moisture is low on the first flush, adjust your substrate recipe to include a bit more until you get it right (field capacity). You can buy a moisture gauge if you want, but with some experience you can measure appropriate moisture fairly accurately using the "squeeze test." (I do not own a moisture gauge.) For those projects where the moisture is low for the first flush and for those where it's perfect, a dunk for 6-24 hours will make for a better second flush.

3. Borrowing a picture here with thanks :smile:

Effect: Yellowing, blueing, or "bruising" substrate.
Cause: Stress! :bomb: This is caused by too much FAE and subsequent drying of the substrate, contaminates in the substrate, dropping your humidity gauge on your friends :uhoh:, direct/close proximity misting, or anything else you can imagine straining the substrate, which is pretty fragile (especially primordia.)
Solution: Take it easy!  :cool:  I would say the most common cause of this one is the excess FAE, so adjust that accordingly when you begin to see bruising, metabolites, etc. Don't try to reverse the drying out effect with extra misting. This often leads to a dense mat of mycelium on the surface discouraging primorida/pins from forming.

4. Borrowing again :grin:

I believe the strain is Mazatapec.



Effect: Tall & skinny mushrooms.
Cause: This one is primarily attributed to excess CO2 levels at the substrate level. In an attempt to escape the suffocating circumstances, the mushrooms put most of their energy into growing taller looking for room to breathe. However, lacking light can also cause this one.
Solution: More FAE to displace the suffocating conditions and/or check your light cycle/rating.

5.
Effect: Hollow stems.
Cause: While cubensis is mostly considered a hollow-stemmed species and some varieties are more hollow than others, this "problem" can be attributed, at least partially, to high temperatures in the fruiting chamber.
Solution: Lower the temperatures in the fruiting chamber and surrounding area, and you will encourage thicker, dense stems to form. As a reminder, colder temperatures will also slow down the rate at which the mushrooms develop. But patience is good, remember?! :strokebeard2: Also, keep in mind that the substrate produces heat (the mechanism behind the convection current of our monotubs), so it will always be a little warmer than the space above the substrate and outside the chamber. :dancer:

6. I don't have any cube pics for this one, but it doesn't matter.

Effect: Cracked or splitting caps.
Cause: Usually this is a sign of humidity levels below the desired parameters. I could also imagine it happening as a result of too little moisture in the substrate, but I am less sure of this cause because lacking moisture is usually related to #2 above.
Solution: For monotubs, mist the walls of the fruiting chamber slightly more often, tighten your polyfill, or decrease FAE by a little if you are using a draft or fan. For SGFC users, you'll want to check the moisture of your perlite and re-moisten it, or add more as needed.

7. No image here because there are too many! :juggle:
Effect: Contamination. :shakefist:
Cause: A wide variety of sources may be at the heart of this one. It could be that our spawn was holding potentially unseen contaminates, say, a minor bacterial infection. If the mycelium has to fight this bacteria while trying to colonize, it will exact energy to these multiple tasks. As a result, the rate of colonization is slowed and/or the mycelium is weakened, similar to us when we have a cold or flu. Contamination of the substrate could also be related to the spawn ratio used in the sense that if the ratio is low, it will take longer to colonize the substrate thus increasing the amount of time for ever-present contaminates to develop a hold on the nutrients.
Solution: I can attest that a properly pasteurized substrate mixed with healthy spawn has a very low likelihood of contaminating. And no, I won't let you blame it on the coffee. :evil2: The best thing to do is be as clean as possible with your hands, breathing, tools, and the surrounding area/air when you spawn your tubs/cakes. Close windows, cough/sneeze into your sleeve, don't play with your dog then use your bare hands to mix spawn and substrate, and make it quick! If you take your sweet time to mix your projects together, you hypothetically increase the amount of mold spores falling into your tubs.

Nice find SGFCchamber. Thanks for sharing it in this thread.

I think the fuzzy feet can be attributed to maybe FAE or maybe its really high humidity or over misting.

Yes SGFCchamber, that's a great find and is exactly the sort of thing I'm looking for  :thumbup:

But feel free to continue and elaborate on such growth parameters & troubleshooting, fellow shroomerites  :cheers:
