New Grower PH CALIBRATION - liquid or packets better?

[gettingreen]

i need to calibrate the hanna combo. should i buy the 230ml bottles or individual packets???

Never used the packets. The bottled solution works fine and can be reused as long as your meter is clean before you do the calibration.

Get the liquid,I tryed the powder and it sucks.The liquid is cheap and one bottle will last forever.:smokebuds:
