why do people call names while their "correcting" somebody??
and then they hold the positive message??
the internet is so funny not often in life does one step between and use added insults to stop an argument??
i think the "HAHAHAH" and gross underestimate of weight regardless of the view from pic were really the start of the out of line and would send most into the same sorta defense of what they are sharing from somebody w/ less than 20 post no matter their resume
you can't fix one side of the track and expect the train to run properly
The answer to the question is the same as always
the proper type of set-up is dependant on your conditions
there are alot of nice tools in the shed now w/ the evolution horticulture has had as of recent years especially
but one tool doesn't always work the "BEST" for every situation
some that run leds need to run dehumidifiers and heaters in some conditions
some w/ hids have an issue venting heat at times
some areas are too confined for hids or leds so clf is the better situation there
just to name a few ,but alot of things go into the decision in the end for what's better for ones garden
But the one thing that doesn't change is that you need to learn your equipment as well as you learn your plants
toooooooooo many wht if'sss and you could 's
You need to know your area and how easy it is to accomplish your mini ecosystem your creating w/in your area
if.. money is no object and yield per plant happened to be the only question(unlike here where the question seems to be per garden) like in some medical states that have a plant limit worry
then go for broke hid above leds as dirrectional accent canopy lighting and cfl's for bottom and lower side branching
see it was that easy
but if overall garden yield was the question ????well this is once the gardener learns how to yield the # in question regardless of the equipment used
And the fan/filter combo shouldn't cost that much.
