I was thinking I wud just move to a bigger room and by 3 more lights . No wait! It just hit me I hv a empty room next to my grow room . So I will vegg all 20 together then when its time for flowering I will slide 10 plants to other for 12 hours of dark. Then I will alternate every 12 hours. It shouldn't be to difficult .house is empty. This way 10 plans under 3000 watts at a time. Holy shit
