Spongebob, that first one is (I think) something close to the $10 ones I was talking about, which everyone seems to keep discouraging people to use, and that second one is to test the PH of your nutrient solution. Incidentally, I think that after the shipping on the PH pen, thats roughly, somewhat, kinda almost exactly what I paid for mine in the hydro shop. You should find it quite handy compared to other methods.

So thanks, but that's not what I was talking about. I was interested in something to probe deep into my soil pots. Something that doesn't suck, and will tell me the moisture content and PH.
