Well if we want to get all hippy about our plants, one could say that a plant is not properly finished until said plant has created seed to reproduce itself. the question you need to ask yourself, are our plants at a conscious enough level to know they have not got any seeds in them.....????!!!??? And if there is not not a chemical reaction inside the plant that allows it to know this (I am not sure if there is or not), then it is all a load of hocus pocus, and the plant is as potent as the growing conditions allow it to be (i.e light, water, food, CO2). That would be my stoned Sunday morning thought. And yeh, in most cases you can't have your cake and eat it. Shame that. Peace, DST
