pasteurization f**k up
« on: June 04, 2010, 03:41:23 PM »

so i was pasteurizing some poo/straw and got focused on something else, but i let the temp get up past 180 for a bit to long i think and went more into sterilization. i know with poo/straw its better to pasteurize rather the sterilize but is this mix still usable? the tek that i was specifically reading said not to let it get that high, so should i scrap and start over or can it be salvaged with just a lesser result?

I'd start over, would suck to waste perfectly good spawn.

I have heard that some coir has trich in it. I have never had an issue, but I don't use coir a lot. I have really only used it in casings and have a brick laying around. Hpoo and verm 60/40 is great spawn IMO. You don't even need to case it. The jars should be alright for a few. The temps could be lowered to slow down the metabolism.

did you mix mycelium? two strains in one pan? if so you should expect a less than stellar result, most of the time when you mix two strains they each fight for food and usually only put out midget fruits of each strain. maybe it will work for you i hope it does, nothing is in stone in this hobby, the fungus will do what it will! keep us posted id like to see some pics when it fruits!

Just make sure your pasteurization is good and that the sub is getting some FAE. Seems like things contam when the air is bad.

Here is something in the works 48 hrs after spawning. WBS/br. rice 2 Hpoo/straw/verm.
It's not so hard, you also have to make sure you drain it well and squeeze to field cap.

dub,
    if u dont mind me asking what is your process for prepping and pasteurizing sub with straw........... i have read quite a bit about it but would just like to get another idea , and im not using a PC just a large pot and my oven went out when the electric company installed our  so called "smart meeter" the other day

Here's what I do...
    I crumble dry horse nuggets and cut straw into small pieces then scoop with a quart sized measuring cup into an old pillow case using the ratio I want. This mix was 50/20/30 h. poo/straw/verm roughly.
    Then I hold the open end of the pillow case closed and shake it side to side, mixing the dry ingredients. Tie the pillow case with a string not leaving airspace and making a loop with the string so I can hang it to drain later.
    Using my PC (it's my biggest pot) I toss in a spoonful of hi-yield hydrated lime then fill with water (mixes in better that way). I use spring but I think any would do. Then place the pillow case/bulk sub in to soak overnight or a few hours and a heavy brick to weigh it down.
    Change out the water and add another spoonful of lime. Heat it up to 180 F (gas stove) and place the sub in the pot. The temp should drop pretty quick, maintain around 160 F for at least an hour.
    I had a lot of sub with this batch and wanted to make sure it was heated properly all the way through so I kept it close to 160 F for three hours, turned off the heat and let it slowly cool for another hour. Then I hung it up over a utility sink overnight to drain. At some point I mixed it around the pillow case while closed to help redistribute the hotter parts for cooling purposes.
