Buying PH Up and Down

[Pay It Forward]

Is it all the same? Can I use the ph up or down that is used in a hot tub to control the ph in my aeroponics system? Or should I continue to use GH PH products?

Peace, PIF

Pool products are not always the same. stick with the GH for ph. Unless you have a huge rez. The real big grows use sulfuric acid, that's right battery acid.
