It's all speculation, with no basis in facts to back it up. People have been suggesting crazy things in attempting to "incease potency" or "increase resins" or get bigger yields or whatever for as long as I've been teaching indoor growing, ten years now.
Here are some facts for anyone attempting to use anything other than good genetics and well grown plants to achieve the goals listed above.
-Cannabis has a genetic potential built into each seeds DNA. This potential can only be reached, it can't be exceeded. We as growers can attempt to grow the plant to 100% potential, but of course there is not real way of knowing what that is because the plant is illegal and the equipment to test things like THC levels cost tens of thousands of dollars.
-The potency of a given plant has nothing to do with the plant! Potency is how the plant effects you and that is determined by your tolerance level to THC. I've been smoking killer weed nonstop for the last, oh, six years now, with little more than a day or two here and there without in all that time. Smoking a gram of BHO to my head would get me wasted, but would put any 1/2 dozen other smokers to sleep for hours if their tolerance level is less than mine.
Want to increse the potency of your pot? The only SURE FIRE way to do that is to stop smoking for a week beofre you break into that new stash.
