I have been adding lime to my bucket tek water to make oyster buckets and it works great and seems to speed up colonization and I havent had the contamn problem I had for a few buckets. per bucket its been about 7.5 qts of water to 8 qts of pellets with a tbsp or 15ml volume of lime added. I know i'm not going as deep into the numbers as you guys but its working. I am still heat pasteurizing though. Not sure why my buckets were contamning. Maybe they were too wet. I can't seem to get any of my azul strain oysters to even fruit out of buckets :/

i am looking for a bulk patereusation method as my PC cant handle the amount of substrate i need anymore... lime sounds interesting... but i thought lime method was for straw substrate only, no bran, no supplements no sawdust.... as you can not drain it...
do you drain your substrate mix? as i noticed you use oak as well... you just put all ingredients together and bag it? or you let it drain...?

Yeah me 2. I mainly wanted to learn/explore this for shiitake since i only use 2-5%bran when i sterilize anyways. I am expecting a 4 month colonization time, so it will be a while lol! I actually made my blocks huge (8lbs or 3.6KG) because i didnt need to sterilize or mix them after they had been loaded into bags. This will increase my yield/ft3 and decrease the use of plastic.

Hey Aleon. One question, did you use the same ratio of spawn for the shiitake blocks (200g wet for 1000g dry sawdust)?
ok two questions do you expect 4 months before browning?
thanks for sharing your experiment.

I need to update the OP with these other experiments. I did 150g wet spawn to 1KG dry pellets for the shiitake.
I expect it to be ready to fruit at 3.5-4 months.

the idea about lime pasteurisation is creating a PH of 12 right? is it therefore ok to use another material for creating ph of 12, instead of using lime? i can get my hands on KOH. so would like to try the lime method with KOH. it only cost me 0,74ct/kilo and liquid so easy to mix with the water....would this be a good idea?
hydrated lime that i can get has a high Mg content and i believe that is not good.

A high Mg content is not good. Im using the HI-Yield Brand of hydrated lime now. Id be interested in your results as i always have KOH around for hydro solutions too. If it is just a PH thing (which i think it is) you should give it a try Also the added Potassium could boost growth as well. I think that the calcium in hydrated lime provides additional calcium for nutrition to the mushrooms as well?

... and being exothermic on reaction with water you could heat pasteurise at the same time!

What I don't understand is...the ideal ph of substrates for a lot of strains is they say, 6. If it's soaked in ph 12, what is the end ph?

As the fungus colonizes the substrate the PH decreases due to the acids the fungus create. Hopefully by the time the mushroom colonizes the substrate or shortly thereafter, the PH should be ideal for fruiting.
Lime will work for the Calocybe sparkle. You should give it a try!

Thanks Lipa, I definitely will try it. I will do your shower tek. I thought the ideal ph is for colonization and not for fruiting. One other question, if the high ph is good for most mushrooms, how will it eliminate our competing mushrooms like this?

I was mixing a very high amount of lime into my casing for king oysters. I would assume, if you don't already, adding a good dose of lime to your casing will help eliminate your weed mushrooms sparkle.

maybe it will stop mold spores from germinating, but mycelium from colonised spawn can make the jump to the alkaline substrate?

I find the pH drops back to around 7 after a day or 2 soaking.

i'm thinking there is still a lot or room for adjustment of the procedure to species that now won't tolerate the lime treated substrate.
for example like i mentioned in another thread afterwards adding an acid to neutralize, then the substrate would be at the same point as heat pasteurized when it's cooled down before inoculation, unprotected against new invaders except by the (wanted) micro-organisms that survived the treatment.

cool! I'm looking to start a little wood pellet fuel apartment growing operation soon. Was never a fan of h202. This looks more convenient and doesn't need to be ph buffered.
