Horizon Nursery

Has anyone dealt with this company?  They had advertised in the past in TFH
as the licensed US Tropica dealer (they just use the tropica method).  They
are located near San Diego, and I will be going to the zoo next week, so I
thought I might stop and check it out.  From what I understand, they grow
them hydroponically, so if I buy anything I should expect a large die back?
