i set a marmite of water boiling...
then i just use plant rests (stems, leaves), and put it with the water... i would say the more you put, the more taste it has... so i didn't care of the rests of my harvest...

anyway, it's good to know thc dosn't dissolve in water... it has quite a relaxing effect but won't stone u...

if u want to be stoned with food, thc dissolves in OIL (oil or butter)... so do what you want with oil or butter... don't forget thc molecules begin to break above 100%c (boiling water is just ok, it's the limit)
