High All, I've been growing a few years now & I have never asked or heard anyone else make mention of how to increase potency. So I'm wondering if there are any additives that help do this or if it's all strain dependent ? I just haven't been totally satisfied with the potency of the weed I grow. I've grown Barney's Farm, Original Sensible Seeds, Sweet Seeds, Dutch Passion & several others; but pretty much the same results. I usually only buy Indica or Hybrid (Indica Dominant) seeds with over 20% THC. Any suggestions on how to get more potent weed ?
