Best medium . . . .

What's the best overall medium for hydro?

I like rockwool myself

clay ball easy , and u can use them again:)

Kinda like asking what the best tire is- gonna depend on the vehicle, how you drive...

Choice of media has a lot to do w/ grow style, disposal issues, budget...

A mixture of hydroton and rockwool cubes....like rhizome replied depending on your budget and diposal issue.

they all have their issues.

Whats the most important thing to you?
