I mean with that logic, you could also use your dehydrator in the same way you can use it to pasteurize substrate no?

I would be wary of the fans pumping contaminated air- which could be remedied if you put whatever you were sterilizing in bags/containers/jars (ala sub pasteurization).

Might be a niche method for a few tools if you wanted to go that route without firing up the oven

Din't use dry heat for substrate. Will dry it out and melt bags.

Your logic is a tad flawed.

160 °F will not melt a Ziploc bag, much less a grow bag.

(I'm not suggesting sterilizing in an oven though. The temperature required would be far too high - the low temp of steam sterilization is its main virtue.)

Tell that to my zaps

In all seriousness Phaethon is right.
160/165 won’t melt ziplocks, even for 12 plus hours.
I’ve done it to pasteurize substrate and there is a few posts around people use dehydrators and ziplocks for pasturizing casing.

It won’t dry out if you leave it unzipped and  fold the under itself so it can vent a little.
Give it a shot homie, it works.

Sure. And you might consider actually reading a linked post before replying like that next time.

It’s okay.
TCs can still learn from a rookie too.

I think the PP5 autoclavable petris are a bit milky/cloudy/opaque.  So, definitely can be autoclaved but they have a real downside

---

The Vabiooth ones are not polypropylene. They are polycarbonate and are perfectly transparent.

Edit: pics



These are way better than the polypropylene ones you are used to seeing.

Upgraded my SAB lid today with boat inspection hatches, im really pleased since before this I used a clean towel to cover the front


The view without the covers, and I made a small table inside of plexiglass and adjustable furniture feet so that I can get it level in my non-level plastic box

This upgrade is cleeeean AF. I'ma have to do this.

Folks used to pasteurize sub/casing in turkey bags in the oven using a temperature probe. Dry heat works for pasteurization but will only sterilize tools and dishes, it won't work for complex loads with heavy bioburden like grains. I've authored a thread re spore pasteurization using a dehydrator, I'm sure an oven would work as well.

https://www.shroomery.org/forums/showflat.php/Number/29130723#29130723

I think there's plenty of evidence that a dehydrator can pasteurize items so long as the item itself lacks any significant bioload. Sometimes it works, sometimes it doesn't For reliable results I'd stick to the tried and true methods utilizing steam/water bath (cleanest), or an oven, depending on item to be pasteurized. A broken clock is right twice/day. The density of the item should be considered as well as the timer doesn't start until core temperature is reached. The septic nature of the dehydrator should also be considered as they harbor a significant spore load by comparison, especially after running Pablo Escobar amounts of mushrooms.

The longer it takes an item to reach core temp, the longer it's exposed to vectors for contamination when being processed using less desirable methods or equipment.

I sterilize them with my agar, wrapped in foil twice in stacks of 5 and placed on top of wide half pint.



I can then fit the foil and plates easily through the arm holes of the SAB to cool. There's only a little moisture on them when I unwrap them, and it dries up fast with the plates just sitting in the SAB




These plates hold so much agar, 400ml can easily be used on 10 plates which is what I've been doing.

Buys me more time with room temp storage

---

Don't forget, with glass plates you also have the option to sterilize them with the agar already inside them. Pre-pour/no-pour style.

It may not be as cool as trying not to burn your hand or ruin plates or trying to keep agar at a certain temp, or as many steps as pouring agar...

But it works for me.
