VARIATIONS IN WEED POTENCY
The potency of a particular weed sample will vary because of many factors other then the variety. Many of these have to do with the natural development of the plants and their resin glands. Environmental factors do affect potency but there are large differences in any variety. These inherent factors must be explained before we can talk of factors outside the plant that affect relative potency. Strictly environmental effects are discussed in Chapter 19.
Variations in Cannabis Potency Within Varieties of Cannabis
There are noticeable differences in THC concentrations between plants of the same variety. Differences are large enough so that you can tall (by smoking) that certain plants are better. This is no news to homegrowers,
who often find a particular plant to be outstanding. Five-fold differences in THC concentration have also shown up in research. However, when you consider a whole group of plants of the same variety, they're relatively similar in cannabinoid concentrations. Type II plants
are the most variable, with individual plants much higher than other in certain canninbinoids.
Variations by Plant Part
The concentration of cannabinoids depends on the plant part, or more specifically, the concentration and development of resin glands to plant part. The female flower bracts have the highest concentration of resin glands and are usually the most potent plant parts. Seeds and roots have no resin glands. These shoe no more than traces of canninbinoids. Smoke seeds will give you a headache before you can get high. If you got high on seeds, then there were probably enough bracts adhering to the seeds to get you high
