I would wash them using 3 tub method. I use 1. water, lemon juice, baking soda (makes ionic surfactant) 2. plain water 3. water with hydrogen peroxide. The peroxide degrades to oxygen and water so no issue with residue on plants. The water temperature is important. Room temp. To hot and terps will be lost, to cold and trichs will be knocked off. If they were grown outside you will be amazed at the bugs and bug poop that comes off them.
