HI EVERYONE THIS MY FIRST GROW WITH A HPS AND MY FIRST TIME DOING A JOURNAL ON ICMAG. I GOT SOUR 60, HBD, AND 2 FEM AUTO ASSASSINS GROWING UNDER A 400 WATT HPS, THERE ARE ALL IN ONE GAL. GROW BAGS WITH DRIPS. THE WHOLE GROW ROOM IS LINED WITH REFLECTIVE MYLAR, AND THE TWO DOORS ARE MIRRORS. I WAS GROWING WITH A TON OF 23 WATT CFLS BUT I DECIDED TO GO THE RIGHT WAY WITH THE HPS. SO FAR SO GOOD.
