how do you measure THC levels?

I have an outdoor grow and at the end i want to measure the THC is there a meter i can buy? How do the measure for the CUP?

Hah that would be crazy if you could get a meter to read the THC content of your bud. I have no idea how they test it though. Scientific shit.

What you need to do requires a few tools:

1. A pipe (bongs, vaporizers, bubblers, or fruit can be substituted)
2. A lighter or match
3. Good music

Next you will follow this complex scientific procedure:

1. Load the bowl
2. Smoke the bowl
3. Be high

At the end of this experiment you should be able to accurately measure the thc content on a scale ranging from snickle fritz to dank ass motherfuckin bud.

Actually Harbour Side Health Center in Oakland, Ca measures all of there pot's THC level. Go to there website. Watch the Vid. They tell you what the use to measure it.
