You guys are getting a little crazy.. lol I bathe myself in fresh virgin goat blood and dance under the full moon... naked.. makes my plants come out good every time... ;)
Do a test.. Chop all your plants in the dark but one. Then turn the lights on and chop that last plant. Label it somehow and treat it just like the rest. tie some string to the buds from that plant or something. Then have a friends or someone set up a double blind test. You have a 50/50 chance of getting it right but I bet you won't be able to repeatably pick the stuff you cut in the dark. One thing to try is to set out 4 samples. But, you'll never know if it's 2 of one and 2 the other or 3 of one and 1 of the other or all of one.
Better yet, end all this nonsense and send samples to a lab and find out for sure.
