the 96x3 will work well for 2 or 3 plants alone. I have one and have done well with it. BUT if I had to do it all over, I would have got 2 of the 46x3 reflectors so I could angle them for better coverage on the sides. live and learn lol. and you cant go wrong with the Mephistos. good strong genetics. as far as the Fastbuds, I just spouted a LSD-25 so we'll see how they do. good luck with your growing.
Thankyou for your advice elsamurai

I was thinking the same about being able to angle the two small LEDs slightly off to either side then just having the one LED above.
Is there a big difference in the reflector series to the older model (white) I saw I could get 2x 300w older model Mars LEDs for approx $200.
Or as you said would I be better off with the 2 smaller reflector series ?
