perfect. I'm basing my drip design on a video I've been reviewing called "I grow chronic" hosted by a guy painted green. Its in a DVD compilation of a bunch of videos that has been really helpful. found it on bit torrent.

there's also one by a british guy that is really good. he's why I used jiffy pellets. He says all you need to do is soak it in water for five minutes squeeze 20% of the water out and you're good to go, versus the more professional/precise way of using rockwool and making sure your water is a CF of 12 and pH of 5.5

does that sound right?

one more ultra green question; is the conductivity factor (or EC) the same/interchangalble as Parts Per Million?

if so does a CF of 12 mean that you are at/under the safe level of PPM?

one last thing (sorry if this is just a beating)
I'm planning on these meters, do they look alright?
