12 years.

Off and on, CO2 mist.

Looks best at 2-3w/gal, more is not better.

Does not matter over 70-95F

Never mattered.

Matters, does best at relatively low KH's, 0-5.
In general, the softer the better.

> Ca (ppm)-
> Mg (ppm)-

At a 4:1, about 2-10 range is good, more seems to bring out deep
reds, many in SF that added small amounts of GH booster has pale
but healthy plants, I tended to have redder plants and my GH is
about 9 where I was at.

Does not matter over a wide range

> Fe (ppm)-

Does not matter, you will not get any correlation due to test
protocols and test kit issues.

3x a week, EI

Plain sand to Flourite to ADA Aqua soil substrate.
Did well in all.
Cables never made any differences I've ever noted after 10 years
of their use.

If you use EI, ADA AS, good light(say 3w/gal), blast the CO2
mist into the plant, have relatively low KH, you can grow
anything you want.
I get maybe 1" a day.
