Edit: Its rainwater that i collected.
You have the best water ever then!!! :), below 50PPM or even at the 70PPM range(i heard in here somewhere) is fine i have heard, but better to keep it at the safe side, and used below 50PPM, but i doubt 60PPM will be bad for the plant, sounds like a good experiment to work on ;) .

That is fine, 50 PPM and under is fine for CP's and some people even use up to 100 PPM.

I just measured another gallon of rainwater i collected at 4 ppm. Just to make sure my meter wasnt broken i also checked tap water, and it said 176, and distilled said 0. So it must be working :D

Hey Daniel, my TDS meter is the same as yours but I got the 6$ one and I didn't mind the wait.

Very accurate, it's pretty cool. Tap water is 120ppm, distilled water is 0 ! :)

Cool sekler! The reason I tried to avoid the China one for 6 bucks is that I would die of anticipation waiting 2-3 weeks for it... Also, I don't always trust overseas shipping, but I'm sure it's just me :)
