Ha I know that's what my dad said. I calibrated it before I left that day with 7ph calibrating solution. But test strips would be a bit more reassuring. I remember getting similar results with my home tap water when I was doing aquaponics. But my solution is a few years old so not saying its entirely accurate. Its a cheap meter also.

Damn. That's crazy. Our's is 6.1. Seems like that would corrode ur pipes pretty quick with lime scale huh.

Ya lime scale is a constant problem. I find lime pebbles in my drip irrigation filter about every month. C.L.R. is a staple around these parts.

I just bought a ph meter, because test strips were telling me my ph was 10 no matter how much lime I added. Either that or I'm color blind lol. Did tests in a five gallon buckets, and I kept getting the same shade of blue everytime the ph went over 8.
I'm still struggling with the lime tek on my farm, going back to heat for a little while till I can get it sorted out. I get slow growth and then bacteria on most bags. I thought the problem was my spawn, and it may be somewhat, but I got some commercial pohu from a friend and same issues. I wonder is the water temperature has some effect? On the days I've made logs, ambient temps were in the low 50s. Could the cooler temp of the straw slow the myc down long enough to allow contams to take over? THe bags wre immediately placed in a 75F room. *shrug*

are you trying lime bath on straw or sawdust. The strain of oyster makes a huge difference in my opinion. you want a super vigorous strain that tolerates high ph. AKA- commercial strain like gray dove, brat, etc. I am leary of lime tek for sawdust personally. I think part of the problem is that sawdust is already very low ph. It may be more difficult to change the ph of sawdust by soaking in lime than it is for straw. that said, folks are trying it and having some success on sawdust.

Lime water tops out at pH 12.3 add more lime and it just goes into suspension to give the milky look.

I was getting pH readings in the 14ph range. There was lime that settled out of solution, but it still read that high. Now like I said earlier, it may just be my pH meter. But my starting pH is also very high. Is there a maximum pH lime can produce or is this just the highest you have seen polarity?

Amanita, I'm using straw. Guess I just need to keep experimenting with strains.
So according to that info, chefin, I'm guessing it's impossible to add too much lime? Or will the non soluble particles mess with mycelial growth in some way? If the average strain likes a ph of 6, it probably won't be thrilled running into solid particles of lime sprinkled through the substrate

Thats it's max. The linked doc concurs. Though if the water was very cold then you are approaching 14. Sus pH meter!

After reading that, my thoughts exactly. The water was warm so no way could it of been in the 14 range.

The fact that only so much will dissolve and using that table and a thermometer would make lime a good pH meter calibration solution!

I have the same problem with testing my lime solution. My strips just never go higher than 10 no matter what I add. I just add til i get a reading of ten then add one more 1/3 cup to my 25gallon or so solution. Probably much less :/ I feel like I'm wasting lime though. I need to get an electronic ph tester. my water is usually no warmer than 50 degrees i bet. So this is a good temparature range to just wait for no more to mix into the solution then stop? I always have a white milky mixture. But it should never have any white appearance when its at 12? If so I will just start eyeing the solution to tell me.

My first bags made on 12/24 are fruiting. We will see how well they do.

i've also been thinking if anaerobic fermentation could be combined with lime treatment. Grain spawn without pressure cooking

I just bought a ph meter, because test strips were telling me my ph was 10 no matter how much lime I added.
I have purchased two types of ph strips, one i got from a brewery supply shop, the color chart on this brand only goes to 10 and from my testing this is true, it only goes to blue (10) and wont read any higher.
The other strips i bought from a local lab supply store and the color chart goes to 12 (purple). the same water that will read 12 on these strips will read 10 on the other strips.
So to those of you who cant get a reading over 10, i would suggest using different ph strips. The strips that give a reading of 12 are easy, cheap and reliable.
