Welcome to the land of Mephistos

Mitch's gear truly is the best
RE: LEDs - CaMg and CaMg and more CaMg.

OF is generally considered a bit hot for autos but hopefully the little gals won't get burned.
You probably won't have to feed for the first 2.5 to 3 weeks.
I used to run

HF but my grow shop was forced to carry East Coast facility product
rather than West Coast facility stock...even though I'm on the Western Slope of Colorado.
The East Coast stuff is having more problems with gnats, lumber, pH issues...
generally quality control issues. Certainly not bagging on your decision just giving
you some stuff to look out for.
Make sure to keep an eye on that soil pH
You are going to LOVE this gear!
