How to use the Sea of Green method for explosive yields

What is the Sea of Green method?

The Sea of green (SOG) technique involves growing small cannabis plants closely together. As a result, the cannabis branches create a canopy that traps light. The leaves convert the light into energy which is a crucial component for photosynthesis.

Why use the SOG method?

Many factors determine the successful growth of your cannabis plants. Most cannabis growers do not have the luxury of space. For this reason, the Sea of green setup is an efficient way to make use of your limited space. Growing your cannabis plants closely ensures maximum utilization of light, especially since the branches create a canopy that traps light which is essential for the increased growth of cannabis plants.

SOG Method

Another benefit that growers gain from adopting the Sea of Green method is shorter turnaround periods meaning there is plenty of time to produce more harvests.

What do you need for a Sea of Green setup?

Before you decide to try the Sea of Green technique, you should conduct comprehensive research to understand the necessary equipment for the process.  The following steps will help you as you prepare for your SOG:

  • Decide on an ideal cannabis strain

Not every cannabis strain will thrive under the Sea of Green technique. You should pick a cannabis strain that is flowers quickly and can grow uniformly. The best strain of cannabis that does well under SOG includes all Indica-dominant strains.

  • Have access to enough lighting

Lights are one of the most important things to add to your grow space. Without lights, your cannabis plants will not have energy for photosynthesis, which is a process whereby plants make food. Although you may have lights, you will still have to develop a lighting cycle. Find the perfect light for your Sea of Green grow. It is important to choose a brand of bulbs that do not run too hot. Your bulbs should be of high quality to deliver enough energy that will maximize the growth of your cannabis plants.

How to SOG

Although the growth of your cannabis plants using the SOG technique will depend on various factors, there are specific steps to follow so that you avoid certain hassles that may hinder a seamless process. You should expect to spend at least one month and two weeks caring for your Sea of Green set up before you can harvest. The step-by-step guide to the SOG growing is straightforward and includes:


Choose a germination method that you prefer. Most cannabis growers decide to germinate their seeds using the paper towel technique, which is common, cheap, and convenient.


Once your seeds form seedlings, you may transfer them to a growing medium like soil or hydroponics.

Vegging plants

This step is crucial until your cannabis plants reach at least 12 inches. However, the vegging period will depend on the type of cultivar in your SOG and how much space you have.

Positioning pots

You should have at least one to two plants per square foot of space. Ensure you provide plenty of light time, at least 18hours, for your seedlings until they reach 30 cm in height.

Trimming, pruning, and fimming

Once a canopy starts to form, it is key that you trim out any lower branches. You nay use the branches as cuts or get rid of them completely.


Analyze your cannabis plants to determine the right time to harvest. When to put plants in a Sea of Green

Sea of Green yields

The SOG method is a good way to reduce overall power and water costs while doubling yearly yields. The explosive yields of cannabis grown in a SOG setup are what make this method popular across cannabis growers.

Best strains for Sea of Green

Amnesia Haze

Amnesia Haze is a stoner’s favorite.  Indoor Sea of Green is the perfect technique to grow Amnesia Haze seeds because it offers maximum yields thus profits.

Big Bud

The benefit of this strain is that it produces big-sized buds that is every grower’s dream. Using the Sea of Green method will help Big Bud seeds reach their maximum potential.

Super Silver Haze

The high yields of Super Silver Haze make it one of the most sought-after strains by cannabis enthusiasts. The Sea of Green technique is what you need as a grower to gain a competitive advantage in cannabis markets.

Does SOG give better yields?

One of the main reasons growers consider using Sea of Green is how easy it is. Moreover, you will not need much to complete your setup, and the results are profound considering the plants go through a shorter cycle. For this reason, it will cost you less power and water, but you will still maximize yields up to double the number of yearly harvests.

How many plants should be put in a Sea of Green?

The number of plants you put in your Sea of Green will depend on the size of the pots. Space availability is another factor that determines how many plants will thrive under your Sea of Green setup. However, your pots should not exceed 2.5 gallons, which would probably handle about ten plants.

Can you use Sea of Green for Autoflower plants?

Yes. Sea of Green autoflower plants grow rapidly and flower quickly. Moreover, these plants are relatively short, meaning they have minimal lateral branching, perfect for the Sea of Green method.

Can you SOG in hydroponics?

Yes.  Sea of Green hydroponics has the benefit of faster growths. However, the setup may be complex and require more maintenance.

Are there downsides to the Sea of Green?

Yes. There are various cons to adopting the Sea of Green cannabis method for your cannabis plants. First, you will need plenty of seeds when starting. Furthermore, because the plants are closely-packed, an infestation would quickly spread from one plant throughout the entire setup causing huge losses.

A common alternative to SOG is to use the SCROG method also known as Screen of Green which can also be used to group plants close together and create a canopy.

Ed Rushford’s impact on cannabis growing is undeniable. Though he tends to focus primarily on 2 areas, plant training techniques and dealing with disease, pests, and other problems, he has offered many insights into how cannabis plants live and grow. That’s not to say that Ed is unfamiliar with the complete life cycle of cannabis, from seed to harvest, but he uses his widespread knowledge to hone in on the minutia and niche areas of growing cannabis. Ed’s goal is to spread knowledge and allow for everyone to become better growers. About this Author
