PH of 7,5 in casing mix 50/50 coir-verm
    #3568368 - 01/01/05 05:16 PM (13 years, 3 months ago)

Hello nasty growers out there :wink:

Q, im about to go for my first real casing. I bought some coir and it says it has PH of 5.

In a 50/50 ratio with verm, how much calcium, crushed oyster shell (garden calcium I bought) should I add to get a PH of 7,5?

Thanks,
MF

:thumbup: thanks Anno!

Actually I did not buy Coco coir, but "turf" something Dutch growers seem to use a lot. But its more acid then coco.

The translator says its "peat"... Hmzz ok then I could have searched a bit after all... :wink:

Thanks ! :laugh:

PH of 6.5 to 8 will work. 7.5 is optimal.

You ADJUST the PH to 7.5

Do you have a tester, or litmus strips?

Yeah 6T said 7,5 is optimum. :wink:
In a 50/50 mix, is 10% by volume still the way to go to get that 7,5 PH?

No I dont have any testers but the simple versions arent that expensive I presume?

Thanks,
MF
