Swopping out lights would not be an issue... I do it regularly with my setup now with load shedding. Tomorrow will be 50w cobs instead of the 150w HPS.
Slurricane one week into flower. She has done some serious streching this last couple of days. And i also remember now why the Sapphire OG was one of my favorite plants outdoors. First pic is the Sapp.
Well a 400w hps will grow you some decent bud. But if I was you I would buy a 75w led from @growopz. You can always add another later on. And then another and then another and so on.
When you are around these plants all the time you loose your sence of smell. But I thing my neighbour's are appreciation it. And every body that visits me always tells me it smells great. Thank you. It has taken me a long time to get here.
