gotcha.. yeah i agree, if they dont answer emails they should write that on the website, so u dont bother. but yeah man i guess it is just ran by one guy, maybe a couple other guys there, but i imageine they get alot of business so i really think that is the case they just dont get around to checkin emails all the time. and im sure they get alot, even just from like people asking questions about certain shit, like "hey what do i need for a hydro set up" and stupid shit like that. he's even a power seller on ebay i think, meaning he sells alot of shit, on there. alot of stuff to keep track of for one guy. but he should hire help, would be the logical thing to do.
but yeah i just imagine if you did call, they would take care of ya.
