Soil is a good idea,
if you don't have your rez temp under control.
That's why I'm growing some hempy bucket,
although HB is still hydro.
The HB rez is small, and gets used up,
so there is no water to rot the roots,
but there is no elements in perlite,
so you need hydro nutes,
since hydro nutes contain micro elements,
that are not needed in soil fertilizer.
You still need to use RO,
or rain water for your soil grow,
if you want to have the best result.
Most tapwater in the USA sucks,
no matter how you choose to grow.
