Finally got enogh for my testers

Yes I ordered my Hanna testers today finally can start a grow log now I feel I have everything I need to grow properly.

Do I need all the solutions they say? P.H. 4.0/7.0, cleaning solution, ppm solution, storage and cleaning solutions.

I only have the testers .. 4 and 7
calibrate it once a month, other than that I dont really worry, cleaning solution is probably a good idea though
