Try using 200 grams, do 2 washes with 1/2 gallon in each, although I'd go straight to 300.4th day of drinking off the gallon I made. Made it around 3pm Sunday. I had 16oz at 6pm wednesday. No effect. 16 oz the first second and third days I felt an immediate effect. so the drop off was steep. No off odors or tastes. just no or very little effect. Original recipe was 100g in 1 gallon. I used our Kadavu, which is normally very potent.
