Help with pf tek?
    #18986611 - 10/16/13 03:11 PM (10 years, 3 months ago)

Sooo for the past week or so, i've gotten into the shroomery and learning about growing. I've watched a few documentaries, read the original pf tek, and watched a bunch of videos on different teks. I feel as if i am missing a few things. Well, here we go:
1) Do you suggest perlite for the fruiting chamber?
2) And if so, how often do you suggest fanning and misting?
3) Does adding perlite change how much you need to mist and fan?

I seem to not understand the whole part about fanning and misting. Could someone please explain them both when using the pf tek?

1. Yes perlite is excellent at holding humidity if your using a SGFC. What kind of fruiting chamber are you planning on using?

2. Depending amount and size of holes you drill the frequency of fanning and misting will change. With 1/4" holes space evenly 2" apart on all 6 sides of a SGFC you wont need to fan or spray more than twice a day.

3. Yes. Without perlite you would need another means of humidification. The only reason you put perlite in the FC is to reserve water for evaporation into the air. Without perlite you would have a dry airy box.

Misting is done to keep a high RH inside the fruiting chamber or fruits may not form / grow very small and shitty. Since mushrooms are 90% water you can imagine they need alot of water to grow. Fanning is done to evaporate water from the substrate surface, this is a pinning trigger. Fanning is also done to remove built up CO2 from the FC which stunts growth of mushrooms, they need plenty of fresh air to grow nice and healthy.

So misting is for humidity, Fanning is to remove CO2.

Thank you for the super quick response. :grin: For my fruiting chamber im just using a decent sized, see through, green rubbermaid container. I was planning on putting perlite on the bottom then setting the cakes on it.  I dont know the exact size, its big though. My friend is keeping it in his trunk until we use it. But im not sure what you mean by SGFC.

This is a SGFC:

ShotGun Fruiting Chamber
Its called as such presumably because it looks like it got shot with a shotgun...

You need to soak the perlite first before adding it to the fruiting chamber. Be sure to put about 3" of it in there, maybe more.

We do not mist for humidity, we mist the cakes to replace lost moisture, then we fan out the chamber to promote evaporation of the water we just misted.

In a SGFC there will be no build up of CO2, it flows naturally out of the top of the chamber riding the heat and humidity currents.

This is what it was designed to do.

Just remember to drill the holes. It will likely get to humid, too much CO2, and promote infection if you dont.
And be carefull, its worth literally measuring 2" between each hole. I eyed a SGFC and had waaay too many holes and it didnt hold a proper RH so it was useless. Had to pay another $7 to build a new one.

Please explain to me what "too humid" means.

We are shooting for the highest RH possible, so how can you have too much of it?

What I mean by too humid is puddling on the bottom of the bin if there were no holes. I suppose "too humid" was the wrong way to word that, could have said standing water, or maybe excessive dripping, which could get on cakes/pins..
