Straw Rot BLACK STRAW, what causes this?
    #4045822 - 04/12/05 02:49 PM (12 years, 4 months ago)

A lot of my straw casings have been infected or have begun to rot? What I mean by ROT is that the straw turns black takes over the mycelium growth and eventually takes over the whole case killing everything? IS this Straw ROT? the straw turns blackish grey, it has no apparent smell. What can be done to avoid this?

Ewwww. It could be black mold. You need to chuck that thing carefully. Usually straw rot is brown and slimey, eaten up by bacteria. How are ya preparing your straw?:thumbup:

pasteurize your straw longer. 160-180 degrees Fahrenheit for 3 hours.

Add hydrated lime or bleach also. It's getting to be that time of the year where straw becomes more difficult because of trich spores germinating outside.

I pasterize my straw for 2 hours at 180o add the spawned rye, compress it and in 1-2 weeks the straw is usually fully colonized, it is not until after 1-2 where i sometimes see the straw start to turn black, and this balck does't seem to stop taking over, is this mold? anyone else have this.

How much bleech would I add to the water, what ratio, and wouldn't this kill or prevent the mycelium to spawn?

It's proly black mold. Molds love straw and will take it over quickly. Add 5 heaping tablespoons of hydrated lime and 1 cup of bleach to a 15 gallon pasturization bath @ 170 degrees. 180 is pushing it. Mycelium from a grain spawn will eat the shit out of the straw with this tek. If you don't have lime, the bleach alone will work fine.

thanks for the advice.

One question, if the starw is fully colonized before adding the casing layer, how would the bleech help? isnt' the bleech only benifical in the rye to straw spawn, untill the straw is fully colonized?

Whats a good substrate to test that doesn't mold as easy as straw?

If your substrate is 100% colonized, it shouldn't have any probs with contamination. If you can get your straw colonized healthy, it's probably to much moisture or a casing depth that is too deep. Proper air exchange is key for keeping substrates healthy. And too much water sitting in the bottom of your tray will spark up a mean contam underneath your casing. Then it eats the shit out of it. Make sure your straw is field capacity when you add your spawn. After 100% colonization, add a casing depth around 5/8 of an inch that's field capacity also. Then pick up the casing tray and get a good feel for it's weight or simply weigh it. Mist accordingly to maintain that weight through the casings incubation until you get a rizome coverage that's even. You'll have to patch spots with field capacity casing material in order to allow some of the other rizomes to catch up.

Thats a good idea weighing the casing but where I am confused is how do you maintain that casing weight, by RH alone?? I read many times never to mist the casing therefore I try to avoid it and having the RH at 80% doesn't seem to maintain the moisture in the case. I mist the terranium but like I said I try not to do it over the case.

There is absolutely nothing wrong with misting a casing to maintain it's weight. The key is not over doing it. Rh will not supply enough water to a casing period. Not optimal RH anyway. Incubating a cased casing is the key part of the technique to maintain it's health. You want to keep the casing material at field capacity until you get a good rizome coverage. Then you can add some water weight and up the fanning to stimulate pinning. Fanning 5 times throughout a day and misting the sides of the tetarrium only. It'll take some time to get right. The added water weight will be the supplier of moisture for a large flush, while not introducing molds and bacteria that will render pinning.
