I already have one baby girl under a 600 watt led, would adding another plant be beneficiary to her or be okay if I want to keep her yield high/decent(around 3-4 ozs+ per plant). I mean what"s the ups and downs, I"ve heard a 600 watt can produce a gram per watt. So what would happen if I had 2? So adding another one, would there be a major effect on my yield and potency. i have a small grow area but its boxed in and great with reflections. What do you guys think. My light is def a beast. Should I stick with 1 plant or start a second 1. if anyones grown heavy weight dream machine, then let me know how you liked it. High wise, yield and time.
