The pH in both of my hydroponic boxes are low around 5 maybe four and a half. I have run out of up ph. This little one-horse town has nothing. Is there something I can do to raise my pH because it will be 7 to 10 days before I can get any through the mail.
@Rusty do you have any liquid kelp or baking soda? Fine wood ash?
I got baking soda, will that help
Should I start with say, 1 teaspoon per gallon
@Rusty I’d start with 1/2 tsp per gallon. It has a ph of 8 but it’s more reactive than liquid kelp and it will increase alkalinity faster.
Tanks for info. now I’m off to see the wizard
Lime be also bring it up if you have any
