I've been growing mushrooms for...oh, about 35 days, and just from that very short experience so far, I can safely say that the bulk of the information found in this particular thread is ridiculous.

I've got a shotgun terrarium, with nine cakes sitting on top of 5" of moist perlite.  The terrarium is suspended within another plastic tub, with about an inch of water, warmed by a submersible heater and aerated with a pump and bubble stone. 

Hanging from the top edge of the SGT is a small four inch fan which blows gently across the top of the cakes, for constant FAE.  Each cake has about a half inch of regular vermiculite as a reservoir for holding water. 

A water bottle, capable of spraying a very fine mist, is filled with hot tap water.  When sprayed through the nozzle, the hot water turns into cool steam.

These nine cakes are getting DRENCHED with this cool steam at LEAST five times per day.  In addition, about a quarter cup of water is poured directly into the center of the top vermiculite layer of each cake per day.

What I've found in my short time growing is this:

1.  You can't water cakes enough.  As long as you've got good (or in my  case, constant) FAE, and no standing water, mushrooms LOVE to drink.  Think about it this way - you DUNK the cakes in water.  Even when there are pins on your cake, you can dunk them and assume that all of the pins will survive.

2.  Having good FAE after liberal spraying creates a cycle of wetting/drying that these mushrooms respond to like nothing else.  I'll spray a section of vermiculite, allow it to dry, and see a little mushroom pin growing from that spot within hours.

3.  My first pins began at the very base of my cakes.  I realized that where the moisture is, is where the pins start to grow.  The water was traveling down the sides of the cakes and the moisture was all consolidated there.  When I added the top verm layer and soaked it, the cakes really took off.

It makes me wonder if these mushrooms could even grow underwater.  Imagine it - you weigh down a cake by some means, insert it into a container of water which can be either aerated or cycled.  Nah, it probably wouldn't work.

I agree evaporation is the key. I spray the shit out of everything i have. I spray heavy on pins too, but I have a martha that allows for prefect air exchange. Its the combination of very little air, and over saturation that can cause problems. If your air is prefect, the pins will have a chance to dry out a little, way before bacteria blotch sets in.

Wrong idea with the heavy-constant spraying, you want the humidity to stay high enough in your FC to keep the surfaces of the cake and mushies from losing water to evaporation. Depending on your FAE it could be 1 time a day, none for a mono tub sometimes, or as many as 5 or more if you have something like a very holey shotgun terrarium. As far as spraying pins-I try not to spray them directly and I don't spray heavily, once again were just looking to bring the humidity back up after fanning. If you spray young pins they will abort.




You were correct on the first 7 words.

It's important for the cakes to lose water to evaporation.  This is the number one pinning trigger.  Even at 99% humidity such as in a shotgun terrarium, the fresh air supply will cause evaporation of moisture from the substrate.  This evaporated moisture needs to be replaced a few times daily with light misting.

We don't mist to control humidity other than that the overspray from the mister re-wets the perlite, which then evaporates that moisture as humidity.  We mist to replace moisture in the substrates, and also to gently dampen the fruits themselves, since they absorb water from their surface, as well as water from the substrate.

Misting young pins does not cause them to abort.  Allowing them to dry out does cause them to abort.

I already stated in a previous post that I misstyped and put evaporation instead of dehydration, it was a simple mistake that I am now truly sorry for.

...and please stop harping on the fact that I didn't know not to mist young pins, it's not my damn fault that there is no screening on this site for the bad information that comes up as a noob is trying to make his way in the mycological world. If even 1/10th of the time that was spent tearing apart beginners over and over in the same thread was spent screening out the places they got that info then this wouldn't be happening. I learned that spraying pins aborts them from this website. Just type in the words drip shield, I dare you.

RR-your post wasn't agressive at all, I've just been told the exact same thing from I'm pretty sure every other person on this thread, many after I made a correction to my mistakes.

No problem.

The 'screening' you speak of is what's going on here and in other threads over the last few years.  Nobody is attacking you, but we're trying to correct bad information so others don't make the same mistake.  This has been going on for years.  Unfortunately, the archives and main site here are full of bad info from ten years ago, that nobody has time to go into and delete.  I've tried, but the task is so daunting with thousands of pages of pure crap, there's no way I can find and delete it all and still have time to make a living.  We've tried to set up various members over the years with the password to delete bad info, but the job has still never gotten done.

I don't pretend to envy the job of the mods., it's not a job I wish to undertake so I shouldn't be noisy, I do see the work that goes into forum, it functions well. It's just killer to get told the same thing so many times by so many people in the same thread.

Agreed.  Ya gotta have thick skin around here.  If anyone is being abusive or rude, hit the notify mod button at the bottom of their post and a mod will handle it.  Otherwise, continue to learn as we all still are. 

I've found much of the advice I was giving even five years ago is now outdated due to the advances in the hobby.  We have to continue to learn and adapt as new information and experience becomes available.  Mushroom growing is an artform and a work in progress.  The final book is far from being written yet.  We're all pioneers, so to speak.

I've also found that I must be very much more careful with my posts. Communication via a forum is often sticky business and it is easy to type a tone that wasn't purposeful+it's very hard to recover when many people are in on the conversation.

anyway, didn't mean to totally misdirect this thread-much thanks for understanding
