Hey all,

I can't afford an EC meter right now. I'm already WAY over my initial grow budget after having spider mite problems and other issues.

Anyway, I picked up some pH strips at the pet store, but they are the color-coded ones where it only has a set color for 6.8, 7.2, 7.8, etc. So, I can't get a very accurate reading, it's all interpolation. I thought I remember seeing some more accurate strips back in Chemistry class many moons ago.

Anyone know if more accurate pH strips that exist and where I might be able to get them?? Like maybe some ones that only have a range of 1-2 pH points (6-8)??

Let me know... I may have to spring for an EC..... ARRRGGGH!!!
