Sea of Green Method (SOG)

Last updated: June 21, 2021

What Does Sea of Green Method (SOG) Mean?

Sea of Green (SOG) is a gardening method that growers use to grow the maximum number of plants possible in the shortest amount of time. SOG is a common cannabis growing technique used to force an early bloom, and therefore an earlier harvest.

Using the Sea of Green method, horticulturalists can harvest their plants at a much younger age. In a SOG set-up, plants are grown shorter than normal and are placed close together (within one or two feet of each other) inside the growroom.

From the edge of the grow space, a person who looks over the area sees what looks like a 'sea of green'.

Maximum Yield Explains Sea of Green Method (SOG)

Growing via the sea of green method doesn’t require any specialized training or equipment and is largely a matter of pruning and lighting. It does, however, require a lot of labor and a large grow space/floor plan. It's important to choose plant varieties that are known for quicker flowering rates and known to grow short and wide, as well as only use cuttings that are of a uniform size and condition.

With SOG, the seeds are germinated or cloned normally, but grown using 18-24 hours of light per day. This reduces rest time and forces the plant to grow faster. The plants are then spaced out to about 1 or 2 plants per square foot. The light time is then reduced to exactly 12 hours, which forces flowering. The lower branches are trimmed off directing the energy into the bloom and the plants are then ready for harvest.

The SOG method is not suitable for most horticultural use because over time it will stress a plant, forcing it to abort its fruit. Some forms of the SOG technique are used in the commercial growing of annuals, however.
