    If you have some spare cash get an Apera PH pen, they are as expensive as Feck but worth every penny,
    eBay item number:253932149166
    For some reason they have went up in 30% since I bought mine. Cheaper if you get them from USA.

    Or perhaps my pen has finally expired
    When I lived at the very very top of the hills in Oldham saddelworth I never needed to use any ph . By the time I?d feed the water the nutes dropped a bit of silicone in the ph was 5.6 I was well happy . At the time uu supplied my water .
