Couple of things... first, while flowering use some blackstrap molasses in your nute mix, second as was suggested dry and cure properly..that will help, third, you don't say how your smoking it....what are you using?? joints?? bowl?? what?? I have found that a waterpipe can make even the nastiest weed palletable. and finally, its a lot easier to grow dirty...its a lot less expensive, and you get great results.

BTW... you don't say what the weed tastes like.... is it real heavy on chlorophyl?? or heavy nute taste?? or??
