I tried to make my own reagents and tested it with two different tinctures. One I made from commercial hemp tea that claims 3,5% CBD, vials on the left. The other I made from my own bud, vials on the right side. First row is the CBD test, second row the THC test.
There is only a very slight hint of pink (CBD) for the tincture from hemp tea.
The blue (THC) for the tincture from my own bud is quite obvious though.
Can’t say I feel very comfortable handling hydrochloric acid, but the result is pretty. I guess I should get proper gloves and glasses at least before I continue.
