need help with ph

I'm trying to find ways to check my ph for my aeroponics res. but don't have the money right now to get a good tester. Any other way to check until I buy a good tester?

not really,
have a look in you local pet shop in the fish section.

€$£30 should get you an okay Digital PH tester. check out E-bay maybe.

yeah, it's either get a good one or get the strips that will get you a general idea of where the PH is

you can buy the stips and any hardware store like HD or lowes, or and garden store. and in the fish section of pet store like greenman said.

Thanks just want first grow to be worth it.

you can get a liquid one with drops at a swimming pool place.

all swimming pools have to have their ph checked and they have kits for that. it just samples the water and tells you where you are at. not expensive.

the strips are ok too
