pH meter question:

Discussion in 'Indoor Marijuana Growing' started by relieF, Sep 2, 2003.

  1. i bought a pH pen/meter but apparently i need a "storage solution" to keep my probe in working condition.

    apparently i also need 4.0 and 7.0 buffer solutions to calibrate my meter periodically. PERIODICALLY? fawk i can't afford that. do i really need to do all this, and where can i get the materials cheap? thanks.
     
  2. 250ml of ph7 is £2.50 ere, i dont bover with the ph4.

    iv had my ph pen about 5 years and aint boverd with that storage stuff either, just get the probe wet bout ten mins b4 i use it, if im usein it a lot i leave the end hangin into clear water. after 5 years its normaly out by about 0.02 after 2 or 3 weeks use if at all.

    id just like to point out this is wot i do. if my pens shagged cus of it thats my prob. u treat ur stuff how u want all im sayin is dont panic about it. most of the instrutions u get with these kinda things r ther so the makers can blame u if anything does go wrong. just like the sign i seen on a jar of peanut butter that said "may contain nuts", its just ther to cover themselves.

    then again i mite b rong..
