If you are able DYI is the best IMO. I have maxspect mazarra p-series. The main problem I have with them is the color ratio. The spectrums they run is the best. RB, BL, UV, CW, WW, they use warm whites instead of reds and yellow which enough of that color is in the warm spectrum. The royal blue to blue ratio should be closer to 3:1, stock it comes 1:1 (for the best growth).
i grew sps really well with just the basic china led ones.
mine were 2blues to every 1 white. it was a nice 20k look.
if i was going to do it again with those ones i would go 50/50 and get the ones what have the control knob on the back for whites and blues...
ebay i thinku can get them for 200ish... not possitive tho.
if u go high end i would say the ai vega blues... i love thoses leds to much.
I also build leds if anyone is interested, I can build you a quality light with a nice enclosed heatsink for under $200. It is very slim and hides everything.
