Re: Dialing in humidity... [Re: Mad Season]

Alrighty, I've got the humidifier set to take my chamber up to 93% RH and then cut off until it reaches 63% RH.  At 93%, the mist is thick enough to give that glistening layer that was mentioned to the bottom of my tub...so I'm assuming that when I have colonized substrate in there, the glistening layer will accumulate on top of it in the same way it did on the bottom of the tub.  When the humidifier kicks off, it will give the moisture that's condensed and collected on the surface time to evaporate. 

63% RH at the low end is a working number.  I'm really not sure where to set this yet, but I do know that I want to provide enough time for the moisture on the substrate to naturally evaporate off before the humidifier comes back on.  The thing that I'm going to have to be conscious of is that the substrate itself provides moisture...so, the RH may never drop to 63% and the humidifier would not kick back on to remist...which would be a major fail. 

The fan is set on a timer that has 20 separate on/off settings, so I've programmed it to run for 36 minutes and then kick off for 36 minutes.  Filling the entire 24 hour cycle with only 20 options was really annoying.  Reminded me of the hot dog bun conspiracy haha.  The fan provides large amounts of turbulent, swirling air flow throughout the entire day...and since the humidifier is set to kick on and remist before everything dries out, I won't have splitting caps.

Now if I could get these damned jars to colonize I could actually do some testing.  I still have five jars of PE colonizing (since 12/23), but I went ahead and did five jars of Pink Buffalo (1/16) because I wanted to go with a strain that had faster colonization times and higher yield. 

This is myc growth, yes?

I fucked up. 110%. Virtually nothing about what I've posted in this thread is a good idea.

#1 - There are way, way too many holes. You need two holes, one for the humidifier and one for the fan...that's it. I've since taped all of the rest of them up and am much happier because it actually holds the humidity in.

#2 - The RH range needs to be 1%, not 10-30% like I'd done at first. The combination of having a zillion holes and a wide range caused the chamber and the trays to flood because the mister would have to run for so long so often.

#3 - The fan cycle was wrong too. Fanning for five minutes every couple hours is excessive and causes the fruits and casings to dry out too quickly. I now have it set to run for one minute every four hours and it's a lot better.

So...no holes, RH range set at 93-94%, fan cycles every four hours for one minute. With these changes, the chamber really is set and forget. Still some misting every once in a while...like every 24-48 hours...but no fanning and great results.
