lol mine always reads 7 too fish. :confused2: i got one the 4 in one testers taht ya stab into ya soil too but i only use it for the light meter on it and the moisture meter setting. i wouldnt ever trust the PH reading or the fertitlity reading on them testers either.i am growing in soil and have a cheap tester from lowe's, but when i stick it im my soil it reads a high 7. so confused!
