First grow, stringy white stuff.
    #17906824 - 03/05/13 07:08 AM (11 years, 26 days ago)

Hey everyone, first post here after a few months in the shadows. My names heshnesh and I live in Tasmania, and I'm addicted to crack.
Just kidding. You can't get crack in Tasmania.

Anyway, on the tenth of February, 24 days ago, I started my first P. Cubensis grow. I thought I'd start off with the PF tek and make things easy but I'm now struggling to see how it's any easier than a bulk grow. After 17 days I dunked the fully colonised cakes for a little less than 12 hours (in the fridge), rolled them in verm and birthed them into my terrarium..

Now the terrarium is basically a 60 L or 15 gallon plastic container with cling wrap as the lid, foil lining the inside (thought it would help lighting.. Hurr.. Also meant I didn't have to properly disinfect the container :tongue:), saturated perlite as humidification and a cardboard flap through which I apply FAE and the odd spray of cold boiled water.

There are 5 cakes inside, sitting on individual strips of al foil, condensation is very apparent on all parts of the container and sunlight enters the room pretty much all day. I fan it as much as possible, between 3 and 5 times a day.

Here is a cake:


As you may or may not be able to see in the bad quality pictures, the mycelium has overgrown the outside layer of verm on the sides and top of the cake, they all look like this by the way, and there is some stringy looking white stuff coating only the top layer.

My question; what is it?

And on a side note, that is always a damn good question. Depending on how you pronounce it. :rasta:

Aaand should I get rid of the foil on the sides of the terrarium, buy a hand held fan and build a better terrarium full stop?

I am at your mercy, thank you for your kind replies.:mushroom2:

Looks ok to me op, The little white dots on top of the vermiculite look like primordia (mushroom formations) and the way the mycellium is fluffing up on the sides is a signal that its about to begin producing there too. Anytime mycellium (once in fruiting conditions) fluffs up, thats when you know to start grinning.

Keep up what your doing, you'll have fruits soon.

Ok will do man, does aerial mycelium have any negative effects at all? Any way to combat it?

Its often a symptom of too little FAE. The mycellium is trying to colonize the air. Increase the air exchange and you will be good. Not really a lot to worry about.

Thanks pastywhyte, I have changed to a different lid which I think will promote airflow, before work tomorrow I'll buy a mini fan and start getting serious!

My advice is not to use a motorized fan.  It may dry them out.  Unless your FC is in a cramped space (no airflow)...but don't use the fan inside the chamber.


It sounds like you possibly have not made your FC to specification.  Did you drill holes on all sides?  Do you have it elevated off the ground so airflow gets under it?

Happy growing..  :thumbup:

It's elevated but there aren't holes in the sides (or in the bottom...), I don't have a drill.. I could have improvised something I suppose but I thought that with plenty of fanning it would be ok. There are holes in the top and the lid allows for air flow, it's also near a window I keep open. I didn't build it to spec but I did make it to allow for light, air exchange and easy access. If you guys think its necessary I can buy or borrow a drill on the weekend.

I would give it some holes..
When the C02 builds up it suffocates the myc,
It's heavier than oxygen so without holes at the bottom of the fc it fills the tank like water would..

Yep, ok thanks. I'll get a drill as soon as I can then. Should've just nailed holes in there before it was full!

Live and learn my friend.  :thumbup:

Anyway, you might be able to just poke a few holes on the bottom for now to release the CO2.  Then once you're done with the first flush and while dunking for the second you can poke the remainder of the holes.

But for now, just give it good FAE while keeping the humidity high and you should be ok.

Not quite, you’re right about the holes but wrong about the CO2 and the reasoning behind them.

It’s to allow air to flow up underneath the SGFC and through the perlite, that’s how the SGFC works and more importantly why it’s so effective.

The OP really needs to build the SGFC to the correct specifications if he wants success.

Actually it's both.  While the CO2 is being released, air is being drawn into the FC up through the perlite.

But I'm not here to quibble over semantics as it was only a suggestion until the OP can get their FC to specification.

I rolled a cake in 50/50+ just for kicks 11 days ago, moistened and covered it for 7 days. When I opened it to see if it needed a patch or whatever, it was 2/3 covered in this ultra white, beautiful mycelium resembling yours. I patched over it lightly to see if I could get it to come up more evenly, but I don't think I should have sprayed it like I did. The Myc came out more uniformly, but it's more wispy now. The pinset is looking great so far, I'll be trying this again for sure!

No problem and it’s all good, but, well…

That wasn't the issue as actually it’s not both and it wasn’t semantics as it was hardly related to the meaning of words.

I was specifically trying to dispel the myth that just because CO2 is infinitesimally heavier than oxygen it simply falls through the air settling wherever it falls which is just ludicrous.

I appreciate you were trying to help the OP but doing so by perpetuating a myth or a falsehood is surely counterproductive?

Like I said I was only addressing the misguided belief that CO2 falls through the air and settles on the ground or that this was the purpose of the bottom holes as is highlighted by your original statement of CO2 being released through the bottom holes.

This would work, if co2 actually sank and settled out of air, but it does not.

You are both wrong.., soz.

http://www.youtube.com/watch?v=fne3CNiwQog

I'm starting to think a sgfc need's a redesign..

:mushroom2:Phil.

Edit: I should follow that up tbh..

In normal air co2 is evenly dispersed due to air currents but when at higher levels, in a sealed environment or when with a co2 producer it will sink..

So in a sgfc co2 will fill up like water in a tank..

I think the sgfc needs a redesign because holes under the perlite won't bring air and moisture up but rather down and out..

It does in a sealed environment.  Which is what the OP has at the moment.  Which is why I suggested poking holes for GE.

Guess what GE is?

Gas exchange.

Guess how that happens?

Convection through the holes.  No holes = CO2 buildup at the bottom.

Don't believe me?  Here's a link.....

M'kay, I'll see your sources and raise you a professional mycologist:  :shrug:

O2 will build up in a terrarium, whether or not holes are drilled into all six sides. The levels will be lower than they would be without holes drilled and/or fanning regularly, but will still be above normal ambient. With oyster mushrooms and lion's mane to name two species that are very CO2 intolerant, you need to fan a few times per day, even when using my terrarium design. The point above is that even with 100 holes in the floor of the fruiting chamber/terrarium, CO2 levels will still be elevated. The holes help, but don't make for maintenance free fruiting. In other words, gravity won't 'drain' the CO2. I hope this clears up any lingering confusion. In addition, CO2 is not the only reason we provide air exchange. The other important reason is that contaminants prefer stale air, while mushroom mycelium prefers fresh, moving air.





Quote:

RogerRabbit said:

CO2 doesn't 'sink to the bottom' or 'pour out like water'. It mixes with the air and raises the CO2 content. CO2 can be measured in the upper reaches of the atmosphere. If it all settled to the bottom (ground) it would snuff out life on earth. Therefore, you can't drain CO2 out of your terrarium by holes on the bottom. Fans in a small terrarium will dry out the air. That's why your current cakes
are blue. They're dry and stressing. You want natural circulation in your FC, near 100% humidity, and enough holes or fanning by hand to get the CO2 out.

RogerRabbit said:

If CO2 was heavier enough than air that it settled to the bottom, we'd all be dead from CO2 poisoning on the surface of the planet. CO2 mixes with the air. To get rid of it, you exchange the air in the terrarium. You can't simply drill a hole in the bottom and expect it to run out like water.

CO2 is found high in the atmosphere, not just at the surface. It's the same in your terrarium. In a completely airtight container, the CO2 would sink to the bottom. Such is not the case with our growing containers. C02*CO2 won't run out of holes in the bottom.

It's widely misunderstood that CO2 is heavier than air, and many growers think it will run out like water if only there's holes in the bottom. The fact is, the CO2 mixes with the air inside the tub and raises its CO2 content. You have to exchange ALL the air in the tub to get rid of it. I simply drill lots of holes in the fruiting chamber, and let nature take care of it.

You want holes all around to create circulation. It's a myth that CO2 settles to the bottom and needs to be 'drained' out. If that were the case, we'd all be dead from the CO2 from the power plants, car exhaust, etc. sinking to the surface of the earth, but the fact is, CO2 can be measured in the highest reaches of the upper atmosphere. It simply mixes in with the air and goes where the air goes.

Drill holes as described. CO2 isn't enough heavier that it will 'drain' out holes in the bottom. You want lots of holes so there can be constant fresh air.

Anyway, you might be able to just poke a few holes on the bottom for now to release the CO2.



This would work, if co2 actually sank and settled out of air, but it does not.




It does in a sealed environment.  Which is what the OP has at the moment.  Which is why I suggested poking holes for GE.



But there are cakes in there right?

Well mycellium gives off heat, so the co2 mixes with the air because of these heat currents...it's like a convection.

The funny thing is I only mentioned the CO2 because it was stated before my post.  The initial reason I said to poke holes in the bottom was for gas exchange and humidity.  I only mentioned the CO2 because it was mentioned previously.

I understand what you guys are saying but why would a mushroom grow tall and skinny when looking for O2 if the CO2 didn't sink naturally?

co2 does sink naturally and cakes do have heat currents that take some away with those currents and all this science has been thought of before and the result is the sgfc! thats y there are holes on all 6 sides!

Thanks for the information guys.

I'm starting to believe that the draining CO2 theory is incorrect myself.  At least to the point of poking a hole or two on the bottom wouldn't change much.

I like the way the community here somehow gets the conversation to start with everyone saying give the fc holes to an in depth discussion about ozone and convection lol..
:grin:

Essentially we all agree op needs more FAE, his question is answered..
Yet we all still carry on chatting.. op might not even return lol..

Considering there were no holes I would stick with my gun's and say co2 sinks but notahacker made a great point, with the myc producing heat even in an airtight container the air would circulate..

I was wrong..

i said naturally hacker lol if you put co2 in a baloon what happens?
the fact of the matter is the amount of co2 generated by a few cakes is minimal at best and the slightest bit of air movement will push it out or the smallest heat current will carry it

Yep it does sink naturally,
It's just that the natural environment disperses it..

That's how it end's up.

The holes in the SGFC are essential, more so the bottom ones. The only point I was making was that CO2 doesn’t fall through air and drain out of the holes in a SGFC and more simply that’s not what the holes are for. The SGFC is an elegant & ingenious design but you only maximise its potential if you build it to the correct specification.

The easiest way of looking at it is if CO2 did settle out of room air and was draining out of the holes in the bottom of the SGFC then it would be taking the moisture of the perlite with it. But as the cakes give off CO2, heat & water then as the CO2 is warmer than the air it naturally rises and it’s this pressure differential that draws air in through the holes in the bottom and subsequently through the perlite thus supplying humidity to the SGFC.

Once the warmer CO2 is mixed with the air and drops to ambient temperatures it remains mixed due to gaseous diffusion.

It doesn’t separate and it doesn’t fall through the air to the ground.

Very interesting.... Haha, well what I've done is poke 2 (3" diameter) holes in the bottom at the opposite end to the lid. Now as we've learnt, CO2 will not drain out like a tap. 'Oweva, when I fan my makeshift SGFC from the other end, whatever air is not displaced from the hole through which I am fanning will be forced out through these holes. As another bonus, the natural air flow from my window entering through the sizeable gaps in the lid will also displace the stale CO2 laden air through the other side.. Which would not have happened before, due to the lack of any level of vacuum suction.

You guys are off ya chops, I love it. Thanks for the help.

Don’t flatter yourself sweetheart I actually thought it was the OP I was quoting hence I was advising that holes in the base of the SGFC were essential, which they are.

Besides which it really doesn’t matter to me who was wrong or right but I do like to understand the how’s and why’s of things and genuinely thought I was helping by explaining why I believed the holes should be there.

Not to worry though, it won’t happen again.          :shrug:


Happy trails.  :thumbup:

I also appologize for my butthurt.  Was uncalled for.  I get cranky without my MMJ.

Cheers to you, and the others and the OP.  Happy growing everyone.
