Solid information thank you. I’ve been slowing wrapping my brain around everything you just described in LED tech and it makes sense to me how you are explaining it. I dont think I will be buying a light that hasn’t been tried and true. The Mars hydro sp250 looks pretty nice with 2 or 3 setup in my 5x5. I mean for only 259 a piece But is it a start to finish light or do you supplement the bloom phase or ONLY use in bloom? Side note I finished my irrigation system last night and it seems to function correctly so I’m down to filling my pots with coco, hanging my selected lights and adjusting timers. I have nutes coming from a friend who will have info on a feeding schedule. Thanks for all the great information I kind need to fill in all the bits and pieces I dont know.
