soil ph meter

[michael]

I want to buy a soil ph meter to check my worm tubs. Do any of you use them? What brand do you recommend?
Thanks
Michael

Interesting idea. I've never used one. I just add pulverized eggshells (and expired calcium supplement powder) to my worm tub and hope for the best!

I did this once using pH indicator strips (a quick google search found http://www.altcancer.com/phstrips.htm). You just take a chunk of dirt mix it in some distilled water and dip the strip in it. I don't know how precise of a measurement you want.
