i am most concerned in quality, but would also like a decent yeild? i can grow in soil outside in summer(did last summer) and i really want to try hydro indoor. Concern is quality and all those chemicals. Any feedback appreciated.

you can use organic hydro nutrients in your system, but you still need to flush with ph balanced water only for at least the last week before harvest

if you do hydro right you will have yields up to ten times of soil.
