Gravity

does anyone know of or use Gravity ? and if so should I get it .. I'm told its amazing and no longer available in California and that makes me want to use it lol. any input would be sweet. thanks in advance.

i used both gravity and ssultra for my last grow.. shit took forever and a day to finish, but i'm sure it wasn't either's fault, just the strain.. buds really looked like they had some crazy ass explosive growth that i've never seen before..
the nice thing about gravity is that you use it at like 1ml/g, so a small bottle lasts a fairly long time.. i'm going to continue using it for my next grow and see how it goes from there.. ime, it's not a bad product..
