PH Meter

This fabulous PH meter is a must for anyone owning a wormery.

Simply place the probe into your compost and wait for the meter to tell you if its Acid (PH 1-6) or Alkaline (8-14) 

The ideal PH is neutral (7)

If your wormery is acidic simply add lots of ground up eggshells (calcium carbonate) to restore the balance.

Postage is £2.00
