Wow! This is crazy.
First off, nobodies even asked if you're happy w/ the one you own. I know I am, so much I just lit my 15'x4.5' w/ Pro-4's.
The guys giving advice here are biased, infamous Amare haters whom ignore results & facts just to hate.
Facts on Amare:
-poeple pay -$2 a watt, nobodies EVER paid msrp that I'm aware of.
-I've never meet a person unsatisfied w/ the product or the service
-great results everywhere you look
-5 yr warranty
-models/fixtures made to suit different grow requirements & sizes
I'm so sorry that you've been greeted by false info.
Aside from the three that are trying to offer truthful info.
They are definitely one of the best out there all around.
Timbers are nice if you want plain cobs & DIY.
Personally, I like the option to veg under my Amare's & firmly believe in the enhanced spectrum.
They beat out my HPS every time. That is documented.
My recommendation is that you look for side by side grows using Amare & Plain Cobs. The results are undeniable.
Good luck!
Be careful taking advice from poeple who don't know anything about the product & selectively disregard the facts.
