I'm always surprised at how many people here use soil. Just an observation.

I don't want to agree or disagree with 24/0 v. 18/6. Although I use 18/6 as a rule of thumb it's only because I feel it's more of a replication of what mother nature would do in a plants real life outdoors. However, I've never heard of anyone going 24/0 with truely negative results. To each thier own.

I agree that water should only be given when necessary in a soil enviroment... overwatering=REALLY BAD.
