Micro Wave sterilization?
    #1108890 - 12/04/02 02:54 AM (14 years, 6 days ago)

Hi was wondering if anyone sterilizes with a micro  wave?Or if this is somehow bad to the media as ive seen no mention of it just of pressure cookers which nowadays are a lot rarer than micros waves? :confused:

casing layers and bulk substr8's i have seen documented sterilisation/pasteurization with microwave. seems 10-12 minutes with seran wrap over a bowl or something does quite well for some folks.

When sterilizing casing substrate.....somtimes. Not the actual growing substrate though. Just nuke for like 4 minutes, stir, then a couple more.

yes it is as long as you poke holes in it to allow the water to escape.

Well i have been boiling them so far in a steamer for 1 hour but was just thinking nuking the jar's may be a bit better as it heats the center of the media better and would use less resources but i think for now ill stick to steaming and just do some experiments with nuking.
Thanks for the imput all  :smile:

I sterilize my coco coir in the microwave. I haven't had a contam yet. I got a microwave safe bowl, fill it with a lil extra water, nuke it about twice as long as it takes to boil water. Quickly take it out and cover it in saran wrap and put it in the fridge until it cools. Just in case I pour some hydrogen peroxide in, get a glove, and squeeze the coco coir really dry and crumble on top of my casing.

I have been nuking some 1/2 pint plastic cups full of brf/verm/h2o.The tops are covered with plastic wrap with a few holes in it,mic'ed for 6 mins and so far ive grown quite a few cakes with no contams at all :smile:  Still prefer the PC though as you can do a lot of jars at once...Peace

For me, it worked better than boiling jars. I used glad 3 1/8 cup microwaveable containers (the flatter the better - otherwise deeper areas will be heated by conduction, not microwaves), I wrapped a large ruber band around the container, placed upsidedown and microwaved on high for 5 minutes, flipped over and microwaved for 5 minutes again. You need to experiment with the water content because you can dry out the substrate and burn it. Also, put the substrate in VERY LOOSELY and leave a little space between the top of the ramsey seal (or substrate) and the lid as the vermiculite will expand quite a bit while getting nuked.

i recomend NOT nuking.  I tried nuking a 1/2pint jar of V,BRF, and water for 6minutes and it completley cooked the brf and the v.  also it smelled horrible, :confused:

most fan dried / decissant mushies should be good for 1+ years, vacuum sealing prolongs storage life as well (do a search for more info)

While you may kill most microorganisms if you heat to their TDP, it's not the most effective way and it's not a sure thing. The big nasties that produce endospores will most likely survive. The best way to kill off microbes and endospores is moist heat and pressure. This is why autoclaving (or pressure cooking depending on your environment) is the standard for medical supplies, canning, lab work, and mycology.

Don't skimp on this. Pressure cooking your jars isn't that hard and it keeps the nasties at bay.

Best use of microwave:

Boiling 1 gallon of water quickly to pour into bucket tek if gas stove is unavailable.

This thread is 13 years old and microwave sterilization does not work....it causes mass water evaporation and fractional sterilization (fractional = only partial) I tinkered with the idea awhile back using verm/brf. .. I did get germination but the sub dried up..... a pot and stove is easier.

that's not what fractional sterilization means.

you can see the theory in this thread.
https://www.shroomery.org/forums/showflat.php/Number/21174437

I don't think I have ever seen a thread where somebody did proper and reasonable fractional sterilization. People say it doesn't work or highly unlikely to work but I have seen none try it. I would discount any who do not follow the actual instructions, just like if some guy said PCs don't work since he PCd for 5mins and failed.

Definitely a personal preference. Every time I've microwaved my casing layers I've gotten contamns. Could just be how I did it thou. I like to stick to tried and true :laugh: while trying new things at the same time thou! If it works it works!
