coir pasteurization
#7934596 - 01/26/08 11:44 AM (16 years, 6 days ago) |

I feel like a fool for asking this, but I must.
To hydrate my coir and pasteurize it at the same time, I was planning on putting my 2 bricks into a food cooler like this http://www.knifecore.com/store/image.php?productid=18903. Add hawt ~8qts water (temps probably around 180) and let it sit for up to 2 hrs. Once cooled I will bring to field capacity and spawn to it.
Would this procedue suffice to pasteurize the coir? Should I just set the bricks and forget, or tend to them making sure the water is surrounding the coir and monitor the temps as time goes on (unfortunately opening the cooler drops the temps)? I also have not decided if I will put the bricks in a pillow case while hydrating, seems it may be easier to use one, though enough coir does get thru the pillow case.
I know many people do not even bother with pasteurizing coir, but I have been having issues lately when spawning to coir (maybe too wet, maybe not prepared well). The one thing in this hobby I detest is failed spawn run. So I have been taking my work step by step, making sure I do everything as best I can. This is the one that counts, everything before and after is gravy.
Your input is appreciated

The only way to know if it will work is to try it. I prep my coir by putting the brick in a large bucket and dumping in a big pot boiling water. I let this cool overnight, and spawn in the morning. This method has worked every time for the 3 brands of coir I have tried, but as always, YMMV.

what about loading your hydrated coir into jars and pc'ing them? I'm not clear as to why this would be better or worse than pasteurizing in 160-180 deg water.

I use this method because it is simpler and less messy while still being as effective as steam pasteurizing in a bag or jar.

if you pc your coir it will be sterilized. then all bacteria, good and bad will be killed. if you pasteurize, it only kills the bad. therefore leaving the beneficial bacteria which is what you want.

You can steam pasteurize in a pressure cooker as well, just don't use the pressure valve and steam the bagged/jarred substrate/casing for 5 minutes or so.

Hope I'm not threadjacking, just trying to learn on this topic. I like the "steam pasteurize in the PC" method as I can produce pasteurized jars of substrate and casing and lid them for future use. So 5 minutes will do it? Lids off during the steam, I assume?

Go for it.
I think I should be okay by going about prepping the coir in the cooler. I think it would be wayyy too much coir for me to prep in jars in my pc...my pc prepares my spawn, 1/4th of my bulk's volume.

Ok so, 5 minutes, at steady steam in the pc without the pressure valve....thats all the time it takes? if this does in fact work to pasturize it, u just saved me a ass ton of work. also, would this method also work with poo?

What makes you draw this conclusion?

Throw all your amendments into a pot, including the proper amount of water. Heat pot up. Stir. Using a meat thermometer, monitor the temperature until the substrate is uniformly about 160 F. Take off stove and let cool for 6-8 hours. Check to make sure the substrate is at field capacity.
You do not want to sterilize bulk substrate.

Always pasteurize bulk substrates. Core temp 140-160F maintained for 60-90 minutes. Use a meat thermometer to make sure your methods are working. I prefer to have a purpose built steaming tub, but you can boil water around jars in a big stock pot to get them up to temp. I never liked the methods of pouring boiling water into a cooler, or straining through cloth, etc, but you can always try whatever you feel like within those parameters. Going to take a lot more than 5 minutes in a steam bath though, glass is very slow to transfer heat so it takes a while to penetrate, but holds for a while.

WOW lol. Quite the thread resurrection here. 01/26/08 ->10/08/09. Imagine my surprise when I saw one of my posts while browsing cult. forum!
I've learned and grown alot since I made this thread (spiritually, mentally, physically, mycologically ). The frustration of trying to get consistent results, yet doing the least work led me up to my inevitable realization. There really is no substitute for proper pasteurization. You may be able to get away with throwing hot water into a cooler and letting it sit, but after tossing many a tub to green mold, after wasting so much time and loosing numerous spawn runs, it was time to do things right. I hydrate my coir, get the sucker into a sack, and heat it in a large pot, with water that is already at temperature. I pour more heated water into the center of the bulk, bringing the pot to full ( I like to think this helps bring the core to target temps more quickly). I close up the sack, stick a thermometer in there, and play the waiting game.

Dude.. the original answer to this thread, the boiling water bucket method, is amazing and simple, i have tried many methoda and i will never use anything else ever again. ..
the bucket will maintain pasteurizing temps for over an hour. and the slow fall from 200 degree to room temp is JUST what the doctor ordered for pasteurizing.

Well, coir alone is pretty contaminant resistant, and you could get by with pouring boiling water on it, but if you have additives (i.e. coffee) you need to do a more thorough pasteurization/sterilization.
On that note, can anyone explain to me why the bulk substrate should be pasteurized instead of sterilized in a pc? I haven't heard a satisfactory answer (its not more work to pc it, so why not?).

well you CAN sterilize bulk but some of the good bacteria is killed in the process.
also the boiling water method keeps the temp between 150 and 170 for well over an hour so even with additives its a good method for pasturization.
