yea I can cover the same ground as with my HPS with next to no heat, and about 150-200W less in total when you count fan`s and stuff I had running to cool the 600W
and plant`s just look more healthy overall, guess the spectrum mostly kick in here, but also the potents is great, now I only had one grow, but it is atleast as potent as the 600W could make em and as compact, and I also feel more safe over all running this light
yes they cost me like 800$ or so, but a 600W HPS would cost like the same over 5-7 years of running just in bulb replacements
what I enjoy the most is the hole growth have become more easy, no heat to fight, and plant`s seem`s to enjoy the light, I also water less and use less nutrients, but Im still working a bit with that, not that same as growing with a HPS, need to find the "sweet" spot
sounds like a good buy, if they are 10 spots and have the same kind a spectrum/out put as my first fixture, and if they aint to old, seems like half price, if he is keen on selling try 600$ for both, in cash, after all he is about to move, right
just make sure they is`t old 1W with only blue/red LEDs, the new one I got is a 2012 model, but still ok, was the newest last year Im sure, and still useable as it do have some white`s in em and a good amount of 630/660nm
but yea, if it is`t totally necessary and you have a plan for next year do it then, and use the extra coin to get some new once, that you know is newest tech and have a warranty aso
I did first go for the LEDs when I had the money, but also at the time where I did have to go and look for a new bulb (maybe one grow left in it, keep it as back up in the basement)
up to you, if he want to split em, or you know another who wants one, you could use the coin and get some fun and experience with a few plant`s and use it as supplement to your "new one" you then get next year as plan ?
many options here
