I'm sure you'll just love it, Anthony.
I'm growing my phrags under 6 T'8 tubes @ 4feet.
RH will depend on the season but normally it'll run about 60 - 72% - higher during the summer months.
Tempts - again depending on the season - 68 to 72 degrees, this will run higher and more constant in the up 70's mid 80's with the warmer weather.
Media - 40/40 peatmoss & bark, with 20% of perlite & charcoal.
I keep my phrags pretty moist 2x weekly during the colder months and 3 to 4x per week as the warmer weather approaches. I use ferts 2 per month.
