Sea of Green vs Screen of Green - Cannabis Lingo

You’ll find hundreds of different tips and techniques for growing cannabis at home or commercially. Naturally, some of these are more effective than others and there is lots of discussion and heated debates around what method is best.

Two of the most popular options are SOG and SCROG, particularly for those with limited space. You’ll want to be familiar with both terms as you head into your growing adventure.

At BCNL we suggest Sea Of Green (SOG) with our boxes, though we have many growers using the SCReen Of Green (SCROG) method as well. While they may sound like the same thing, there are some key differences between them. Hopefully this getting started guide will give you some details to increase your familiarity.

Sea Of Green (SOG)

Example of Sea of Green (SOG) method.

This method is known for quick grows using smaller weed plants. The time to harvest is reduced because it requires less time during the vegetative growth cycle to produce a greater yield.

Your plants are tightly packed in the grow area to take advantage of as much space as possible. This results in more even lighting coverage across the canopy, contributing to top buds that grow at the same rate.

With the high density growing and reduced vegetative cycle, you will also be able to harvest your grows up to two weeks sooner. This could really increase the yields of your annual harvests.

Pros of the SOG method:

  • Great for limited spaces
  • Faster grow times
  • Higher yields
  • Less time training plants

Cons of the SOG method:

  • Requires more weed plants
  • Higher maintenance
  • Not a good option if you have plant limits
  • Greater chance of disease or pests spreading

Screen Of Green (SCROG)

Example of Screen of Green Method.

While the SCReen Of Green method is similar to SOG in that you’re maximizing the use of your space, it’s different in that it uses a horizontal screen/grid/mesh system over top of the plants.

This screen allows you to tuck branches and leaves underneath and trains the branches to grow into that space. This allows you to bring the lower buds, or flower, into the canopy to be exposed to more light. The less light the flower gets, the less yield it can produce.

You’ll effectively be growing your plant horizontally while you train the branches. The even light exposure on the canopy of buds will ensure the plant dedicates energy to growing them as full as possible.

Pros of the SCROG method:

  • Less plants if you have growing limits
  • Takes advantage of available space
  • Even canopy for light

Cons of the SCROG method:

  • Higher maintenance
  • More plant training required
  • Longer growth phase
  • Less crops per year


As you can see, both SCROG and SOG are quite similar, but also different. Each serves its purpose and we’ve had customers use both methods with success in our grow boxes.

As previously mentioned, we suggest using SOG and we would be happy to provide some guidance getting setup and maintaining the grow if you need it.
