I heard somewhere that if one had a plant near harvest he or she could harvest the top layer of plant and leave the other bottom layer(s) to get more light for a few weeks, then harvest the rest of the plant. Has anyone does this? Harvesting in a tiered way is appealing to get fat buds on the bottom of the plant just like on the top (obviously). But would this stress the plant too much? Any info is appreciated. I tried searching a number of different phrases but couldn't find anything that way.
