RH is how saturated the air is at its current temperature.  The more saturated it is the harder it is to move water into it and when it reaches 100% saturation it dews and turns to mist/clouds/rain/dew.  Warmer air has a higher holding capacity than colder air and thus heating up air can reduce its RH and cooling off air can increase its RH, where the temperature it reaches when it hits 100% RH is called its dew-point.

Since drying is pumping moisture from the shrooms into the air, the total amount of water vapor in the air is less important than how likely it is to absorb more.



Thanks! That really clarifies it.

Learned something useful today :thumbup:

Yea air drying sucks. Who air dries?

OP did you do this experiment outdoors in the sun or not?


Edit: 
Quote:

The important point is the final relative weight: For the dehydrator it bottoms out slightly
below 8%. In open air this value is almost obtained as well, but after a much longer timescale.
On average it is slightly above 8%. This I attribute to the rather low humidity in the room,
in general I expect open air drying to perform worse, so it might end up at 10% or even higher.

Interestingly, even though the final relative weight of all fruits was rather similar,
only the ones from the dehydrator were cracker dry, while the open air dried ones still
had a certain flexibility.




When ever i do mine outdoors in the sun there isnt any flexibility left. your response would be nice and thanks in advance OP

TY for the excellent post--I am new to this and really learned a lot.  Can you share what type/brand of dehydrator you use or recommend?

Nice scientific research on drying.  However, have you noticed any difference in potency between air and dehydrator?

The humidity in my house is currently in the 5% range and Temps 78-82°F

I left some to air dry on paper towel, sone in light fan and others in dehydrator at 170°F.

The ones in the dehydrator all turned dark and more shriveled although they only took a few hours.

The air dry ones took about 24hrs to be mostly dry, 36 to snap cracker-dry. They retained their nice golden color and general shape.

My climate allows it but the visual impact of quick drying above heat is a turn-off

man if u would have used the search engine u could have found literally a gazillion threads about how air drying and desiccant drying sucks balls and that a dehydrator was the best way and if u ask me the only way to go. you really could have saved yourself a lot of time and you could have made graphs and done all this typing for something useful. i appreciate the effort and all but all i ask is why bother for something as well known and absolutely already proven as this??? just makes all that effort not worth the effort🤷🏼

Are the white chips at the bottom of the airtight storage container a desiccant?

Does anyone start with air drying and then move to a dehydrator to finish/buy time while the first round is in a dehydrator? I was thinking drying racks with a fan and a dehumidifier in the space to pull out a good amount of the moisture, and make larger fruits more manageable for a  dehydrator.  I have a 9 try excalibur to start, and two large hanging drying racks previously used for cannabis. 
Thoughts?

I'd just use the oven for whatever you can't fit in the dehydrator. Then you can do them all at once.

May I ask what the risk is of air drying prior to using a dehydrator?
Thanks for the response.

There's no risk, but without the heat the rate at which they'll dry is limited.

Well, I guess it all depends on the success and timing of fruiting....:wink:
Time will tell.  I'm just doing my first round.  Thanks for the information.

I've done that plenty. Works fine. I've never noticed a potency loss from leaving them to dry on a screen with a fan for a day before throwing in the dehydro.
