Waterproof Testing Pens - Worth every penny
Thanks for the info Rusty :thumbsup:

I folded the paper towel twice, so the run-off went through 4 sheets and came out "clear" in my eyes, if there was a tint I sure couldn't see it. And the results were exactly the same also. It's hard to tell with those color comparison tests, I can't say anything for certain with these POS. I had some problems with one of my plants, but I'm doubting it was a ph problem now. I'll use a coffee filter if I have to do this again... hopefully not The brand of paper towels is Floralys "environmentally friendly", and doesn't say anything about bleach but who knows. (not sure if that was a serious question...kinda :stoned: )

Also thanks for the link Treetops. Looks like I'm going to Holland this summer, and I'll end up shopping around there looking for new supplies. I get really nervous if something is so inexpensive though, and in the end I always buy the one I should have from the beginning... live and learn :jointsmile:
