This concept is going to sound backwards to many of you, but our years of cannabis growing experience have shown that the best way to produce the highest quality product is to cull plants at each stage of growth. Professional gardeners know this rule well, but most cannabis growers do not. In fact, it seems backwards to many cannabis gardeners to throw out plants as they are transitioned through the different stages of the plants life-cycle (i.e. clone/seedling, vegetative, flowering) as they have put effort in keeping these plants alive and as healthy as possible. However, culling plants at each stage will produce a more robust and higher yielding crop through the selection of the strongest individuals and the discarding of weak plants.
