cool. thanks dive. my wife picked me up some test strips while she was out today. they test from 6.0-9.0 or something. i'm not quite sure how to use them.

i haven't read the directions yet though. i know you dip it in the water and match the color.

do i need to test my tap pH? the mixed nutes pH? and what exactly is runoff pH? is that when i check the water/food that comes out the bottom of the container when watering/feeding?

thanks for the help. i know they are some stupid questions. i'll be off reading up on it.
