Been growing in dirt for a while, using chem indicators for pH and TDS. Worked well.

Grew last batch in a drip/bubbler hybrid frighteningly similar to one of the systems I saw on the board recently.

Anyway, using the chem indicators is a bear but the hydro results were superior even on my first try. What brand are you guys/gals using? Combined meter, or separate?

Any models that you can simply leave in the resevoir, or are they too delicate?

Thanks
