do what andre said, i harvested my auto a few days ago and their was a load of small pop corn buds that id normally put in the trim box, but instead of harvested the top of the plant and left all these scrappy buds, well now its been a few days these buds have gotten really bit and im looking at getting an extra 7g dry off it, where as before i would not of used it for smoking it would of been for hash or butter, but after watching how quick they grow and fill out im going to do this every time, the one bud the highest one has sort of become a main bud and has got about as big as a thumb, where as before it was a tiny bud at a lower node, now its getting bigger, the other reson i did this was to test the bud at different stages of growth.
i harvested the auto when all trichs where cloudy, so now i have left it longer its now getting a few ambor trichomes, so now i can try an see which i prefer for future grows, doing this with the same plant tells gives me the chance to compare the different aged bud, then i can choose when to harvest next time round
