my PH up and PH down isnt working!

I bought ph up and down from the local pet store but it doesnt seem to do much unless I add alot..(i have a hydro system with 2 gallon buckets for each plant) ...does anyone have any recomendations for adjusting PH?

Yep...start using RO or distilled water and add CalMag to replace lost minerals etc....

Also you should be using ph up and ph down from a hydro store....not a pet store. The ones for fish are too high in salts for hydro and can harm your plants.

Exactly what Weedhound said. Not only are the pet ones more harmful for your plants, the hydro adjusters are more helpful.

well there are no hyrdo stores around me and I am not to good with the internet, do you know of any good sites to get the hyrdo ph stuff?
