Water farm Module Question (Ph Ppm) Not Kit.

im using 2 individual waterfarm modules
and i soaked the rockwool and cleaned my
hydroton with a 6.5 water and everyday when i
wake up the ppm is higher and so is the ph..
can any1 please tell me why i know that the
waterfarm 8pack has this problem but not the individual
modules too!?!?

thank you all for your help

sup pup... i too use two waterfarms and when i first began i had the same problems you are encountering. my prob was that i wasnt using a sufficient ph meter. i was using one for soil and it would always read high. then i would add ph down. i would have to add soo much that it raised the ppm. i was new to hydro. i then got a ph test kit for aquariums and found that my ph was pretty much fine the whole time. having said all this i would note that i was using distilled water. now i rarely have to adjust the ph... still using distilled h2o and GH flora series nutes. hope this helps

i appreciate your help
but im def. not using a soil
meter this was bought from a
hydro store and only works for
hydro. i used ro water which is basically
the same.
i appreciate it though and good luck
on your grow!
