No problem.

Altho I've never grown hydro, I have had friends that were mighty proud of their accomplishments using it. I was always under-impressed. They looked great while growing, and I guess it got you high ok, but were lacking in flavor.
I much prefer my soil grow. To me, it's easier and cheaper, no risk of clogs or fittings coming loose. Others proclaim it's advantages, but it's just not for me.
