Just got a vaporizer and have been vaping weed after taking a few months off of using it 3-4 times a week. So I have Master Kush and Jack Herrer, the Jack is a pretty heady high with a slight body high but after a few hours all I want to do is sleep. When smoking the Master Kush I feel it a lot more on my body but I don't get so tired after a few hours. Why is this? No I don't have the strains mixed up.
Do you have access to a magnifying glass or microscope? One probably has more clear trichomes one probably has more amber trichomes. You can grow the exact same strain (cloning) harvest 3 weeks apart and have 2 different types of highs from the same exact genetics.
