Why would pot growers pay for shipping? There are a ton of hydroponic stores online that give free shipping over a certain price. From my readings they spend a lot more than I am willing to on different
nutrients and additives lol..
There isn't much here about hydroponics either.. Virtigrow is just up the street, but I was less than impressed with their settup. you can't really tell if they are doing hydroponics without knowing that they told you it, because you can't touch the plants to move a leaf or they yell at you....
There are regular events about an hour away in Orlando though. From what I understand there are hydroponic nerd collectives there that run hydro conventions. (kinda like a scify only with plants)
