I have been drying my bulk grow on a fan. It dried to a crisp and then I store them in an air tight Tupperware-like container. After a night I will check on them and they are soft again.
I've even used those bags with the beads on the container and still, same issue.
Advice would be welcomed, please.

I use freezer ziplock storage bags?

Why freezer bags? Because, the others are O2 permeable; and oxygen aides in the oxidation of the psilly molecule.

Sometimes a material feels dry but there is residual moisture inside cells that softens the material overnight , simply dry a little more and then put into storage, I like mason jars they come in sized from 2oz to half a gallon.

edit- maybe your container is not as air tight as it seems

Depending on the relative humidity where your at fan drying may not be enough. Sometimes it takes some desiccant, or some heat to drive that last little bit of moisture out.

I live in subtropical climate, so I use heat. I have a 9 tray Excalibur Deluxe that is a real work horse.

Probably not all are as dry as you think. I don't believe fan drying will ever get them cracker dry. Without a dehydrator you pretty much have to finish with a resistant.

If you successively add mushrooms to the same container moisture content is going to equalize. One batch not fully dry will turn them all soft.

Also anything moisture content over cracker dry makes them subject to mold.

Add heat or a dehydrator. If it is moderately humid you can not just fan dry them to cracker dry.

Maybe like a space heater?

With a little care you should be able to make it work,  just be careful you don't start any fires. 

 

A dehydrator works best IMHO, but if you don't have access to one, you can also use a sheet pan in a warm oven.

Does your Excalibur have a variable heat setting? If so, what temperature do you safely dry your goods with the least loss of potency?
My dehydrator goes from fan only, then 95 F through 165 F.

Just wanted to add a note, the only time I've seen potency loss is tryi g to use an an oven. An oven is not the same as a dehydrator. There's no air movement. Better off with a a fan and finishing with dessicant.

I've screwed the pooch twice with large amounts of mushrooms in the oven.

the OP can make an inexpensive and reusable desiccant by taking 3 - 4 ounces at a time of Epsom Salts and boiling off the water in it. The crystals contain moisture, if you place the crystals into a microwave safe upper ware container and microwave on high untill all visible moisture is gone; note you want to keep a mug of water in the oven all the time so it does not run with no absorption inside of the oven. I microwave dries 3 ounces in about 4.5 minutes easy. The dry Epsom Salts is said to absorb over twice its weight in moisture. I dried about 0.7 of a litre of Epsom Salts in a microwave safe tupperware container took about twenty minutes. That's a lot of desiccant.

   Fan dry off the bulk of the mushroom moisture then place into a container with the dry salts and let them do the rest to a cracker dry state then pack into freezer bags with as little air as possible.

So, here is what I've done with semi decent results.
Air drying to the point where it feels dry, even a little mush but not much. I took a huge, wide mouth jar and put dessicant at the bottom (about a 1/2 in). I covered that with a layer of tyvek and put the air dried mushrooms on top and replaced the lid.
So far, it has worked wonders. When needed, I can remove the shrooms and tyvek, put the jar in the oven, and bake the dessicant/sterilize the jar.

I'm with Heirloom. Cracker dry however you have to to get there, then into glass jars with a tight lid. They stay dry and keep just fine that way.

Cabela's has a couple of really big dehydrators for not a whole lot of money if you are into that kind of thing. Probably the best value for a big dehydrator.

I have caused a few bleeding gums with shrooms splinters by overbaking myself.
