I'm a newbie with 5 plants indoors harvested with a 6th on the way before that I had only grown a few times outdoors with mixed results so I'm by far not a expert but I'm doing okay with the kiss method. They are fast growing plants when the environment provided is right and they have the food they need to thrive. The light you bought isn't to bad of a light, my first grow I used 2 SF 1000's along with a 315 cmh during flower and I was pretty happy with the results. Actually only used 1 SF 1000 and a couple of shop lights for veg in a 4 x 4 x 8 tent and then added the 315 and a 2nd SF during flower. I like how controlled the environment is when growing indoors. Good luck with the grow and don't be surprised if others chime in, many folks here have great information and are pretty willing to share.. Peace
