Sea of Green also known as SOG = method of growing short plants quickly that just have 1 main cola to harvest, since the plants are smaller you can get more per square footage or square meters as in m2. SoG is a perpetual method originally designed to have many plants in different stages so that it is possible to harvest some every 2 weeks and to keep doing that for as long as needed. SoG is grown using clones, never from seed.
