Pinning humidity level
    #13819075 - 01/20/11 07:49 AM (13 years, 10 days ago)

In the FAQ it says -

"The relative humidity should be from 95%-100%, temperature between 70°F and 75°F, the fruiting chamber should be vented 2-3 times a day to displace the CO2, and they should receive a couple of hours of either indirect sunlight or fluorescent light. "

Is this entirely true? or is it possible to initiate pins at a little lower level of humidity like 80-90%???

I find with cakes, the higher the humidity the better. lower humidity will make it take longer.

like he said they will pin it will just take longer and your flushes will be crappy but i have done fine bouncing down to 70% every so often then raising it back up when i notice.

Try fanning more often... I fan 6-7 times a day n mist 3-4 maybe try plugging a few holes if u are using a sgfc...

fanning more often will just dry it out faster....I have plugged many holes, and use a fan for 2-4 minutes 3-5 times a day.  I mist 4-8 times a day depending on the Humidity level, i will keep trying different combinations until I get the right one, currently i have been able to maintain at least 80% and sometimes getting to 100%, so i will try to get it to be 90-100%.  It's getting more than enough FAE considering i have only a few small cakes in there.  Hoping to add more soon that will help up the humidity level too.  I'll see how they are doing in one week.

80-100 humidity is perfectly fine, just mist your cakes and fan right afterwards...the water evaporating from fanning will cause pinning

Depends what we're talking about. If it's a bulk sub that holds a lot of moisture it'll pin fine around 85, even 80. But if we're talking about something that doesn't hold a lot of water like a pf cake or straight grain, you want to try to keep the humidity up higher.

By the way if you're talking about a shotgun fruiting chamber, don't even worry about the reading on your hygrometer. If it's built to specs, it'll work. Most hygrometers are crap.

would it make sense to put small clear palstic cups with holes over the cakes for a week, taking them off when i fan and mist, in order to raise the humidity for those cakes and induce pinning?

Not necessary, but it kinda sounds like it might work. Similar to wax paper, or Ozzie's shower cap in bucket.

The FAQ is so horribly outdated that it's nothing more than an archive of 'how things used to be done', before we knew better.

You don't want to vent a fruiting chamber 2 to 3 times per day.  It should get more fresh air than that per hour.  That's why the shotgun terrarium outperforms everything used in the early days when that FAQ was written.

In addition, you want nearly 12 hours per day of very bright light for best pin formation.  Furthermore, the air at the surface of a substrate which is evaporating moisture into the air is by default very near the dew point, thus perfect humidity.  If your ambient humidity is only 80%, you can make up for it by misting more.  However, building a proper fruiting chamber will be all you need to do.  If you build a shotgun terrarium per the tek, your humidity will be correct for pinning, despite what a chinese 'hygrometer' might read.  You still need to mist of course, but don't obsess over humidity.

How often should I mist?  I have a fan right next to my shotgun FC, I usually turn it on for 1-3 mins aimed directly at the side of it like 4-5 times a day, and currently I mist about that much, 4-5 times a day.  How does that sound?

I can't possibly count how many times I've posted not to have fans anywhere near a shotgun terrarium.  They destroy the natural air currents that make a shotgun terrarium work, ruining the humidity.

so i should scrap the fan, and just use the cover to fan?  I was substituting fanning with the cover, with just turning on the fan next to it for a couple minutes, what's the difference?

Im just replacing the air in there with fresh air

the fan is off otherwise, all day, just on to replace air
