I don't know where kelp farmers hang out but apparently not on a 420 sight...
Joking aside, what were you trying to ask? Kelp is a common gardening amendment but I have not talk to a single person on here that gathers there own kelp, much less farm it. Is it even farming if you don't propagate? Seems closer related to off shore fishing or wild gathering.
there was one guy who used to gather his own seaweed for fert, but he's long gone. 98% of us aren't anywhere near an ocean coastline so the post is kind of a useless inquiry.
