I was hoping to hear some info on flavoring pre-harvest using an aeroponic system. i have come here often over the years and found what i needed with no problem. However, i have not found enough info on this. I would like to hear some feedback from someone who has done this before in a similar system, (1) The method they used and (2) the outcome as far as the positive/negitive affects. (3) Does the Vanilla, Lemon, ect... cooking extracts contain harmful carcinogens? if not what are the best to use with the best outcome in flavor. I am on my last week now with just water and am feeling froggy. I would appriecate all feedback, but please stay on topic. thanks.
