I used blurple leds, 3100k cmh, 4200k cmh, hps and T5. Just went pedal to the metal for a while. Spunked £840 on electricity in just 2 months. Sure got a lot of bud back though. I've still got 12 plants growing. Harvest next week for them.
I don't weigh up, also only grew 3 of this strain. They are better than average for normal auto yields! I just know by eye there is more than the average auto I grow.
