Ok I know a lot of ppl think you can only get quality bud from hps,this is simply not true.I always have nice hard nugs and great yields.Yes it does take some growing experiance to produce nice bud and big yields.These are some auto afgan kush ryders about 3 weeks from harvest.I use smart pots and quantum t-5 bad boy 8 bulb lights.Most grows that are using 400 watt hps would probably do better with t-5 ho as on an 8 bulb your pushing 40,000.lumins with a great color spectrum.2 ounces a plant are on the low end for yield with this set up.
