Can you please give me an example of how hydroponics is done, e.g. potatoesi know what it is but whats the method for potatoes? or any other?
A system described in link.
It's just the way it's grown and it's not solely for cannabis either, basically it's an elaborate system of pipes and soil that allows for a constant replenishment of the water supply, usually fertilizers are added in to promote faster growing and make said plant more potent. Never heard of anything harmful in it though.
