Do you take measurements? If so, you can use Herb.IQ to keep track of all things grow-related, and encrypt it to a solid standard as well. Software was written by one of RIU's ownBack in just a lil' bit!
Thanks i'll make sure to check it out once i get it. I will be taking measurements of PPM if thats what your asking? at the moment i have no way to test it. when i water tomoro i might get distilled water and use that untill i can measure. he said he keeps it at 350-400 and i should keep it around that because they like it. So hopefully the distilled water will at least be better than my tap water.
