The HLG 300L by itself in a 2x4x6 is not enough light. Im going to put the intake and exhaust fans out side of the tent after this cycle to clear some space and add the 2nd 150w HPS. Theres no reason why I shouldnt be pulling 6-8 oz every 60 to 70 days. These bag seeds look like sativa doms so they are probably at least 63 day flower.
