Sea of Green Method (SOG) For Autoflowering Plants

Sea of Green Method (SOG) For Autoflowering Plants

The Sea of Green (SOG) method allows you to fit dozens of smaller plants together to create a dense "sea" of buds that fills your entire grow space.

In this guide, we'll break down how this SOG method works and why it's so beneficial.

Trust us; if you've ever felt held back from growing cannabis due to limited space, you may find this method very, very helpful. 

What is the Sea of Green (SOG) Method?

The Sea of Green or SOG method is a technique used to grow cannabis indoors.

It's an efficient process that involves cultivating many smaller auto-flowering plants close together.

The SOG method eliminates the usual vegetative stage of growth, taking the plants straight into flowering for faster turnover. The key goals of this method are rapid harvesting and maximizing yields per square meter of grow space.

To achieve this, the grower places the plant's pot to pot and aggressively prunes them to keep them relatively short.

With the SOG technique, the same space can hold more plants compared to fewer, larger plants.

This high-density planting is ideal for auto-flowering weed strains that start their flowering stage based on age rather than light cycle.

By skipping the long vegetative phase, SOG allows for more frequent harvests.

Add efficient light distribution, and the Sea of Green method can further optimize cannabis yields indoors.

How the Sea of Green Method Works

Step 1: Choosing Strains and Plant Placement

Start by picking autoflower strains that work well with SOG.

White Widow Auto or Northern Lights Auto are excellent examples.

Then plant your weed seeds in small containers (around 1-5 gallons) and keep them as close together as possible.

Keep maybe 30 cm (12 inches) of space between each plant so they can grow comfortably without their roots getting tangled.

Step 2: Pruning and Training Plants

Once you've picked your plants and spaced them out, it's time to prune and trim.

For SOG to work, the plants' sizes need to stay compact.

Cut back the lower branches and leaves to focus growth up top. You can also use some gentle training techniques to encourage the plants to grow outwards a bit.

This can create a flat canopy that evenly distributes light, ensuring a better yield.

EXPERT TIP:  Try to keep plants of similar sizes together for an even canopy.

Step 3: Navigating the Vegetative Stage with SOG

When your weed plants are in their vegetative stage, you need to make sure they develop a good structure.

With the SOG method, you want a thick canopy of buds, so the plants need a solid foundation to hold that up.  

While in this stage, remember to keep adjusting how you train and position the plants. Do it regularly to help all the parts get light evenly. This will make the plants grow strong and sturdy.

Step 4: Flowering and Harvesting Stages

The nice thing about autoflower strains is that they start flowering on their own (typically 2-4 weeks from germination).

But don't forget to monitor your plants closely during this stage, as the time to harvest can vary.

Trust us; you do not want to miss that window.

Harvest plants as they reach peak maturity and replace them immediately with new seedlings to keep the cycle going. 

This staggered harvesting approach allows for a perpetual harvest, with plants at various stages of growth occupying the grow space.

Using the SOG method with autoflowers takes a bit of planning and care, but all that effort can pay off.

It's about smart space use, managing your canopy, and moving the grow cycle. Remember, the goal is a lush, productive canopy that makes the most of the grow space.

10 Tips for Successful SOG Grows

When using the Sea of Green method to grow autoflower strains indoors, here are some useful tips:

1. Choose Indica Seeds

Generally speaking, any autoflower strain is compact and high-yielding.

They also transition to flower quickly without changing light cycles. This makes them ideal for the SOG technique.

To improve your chances of success, choose an Indica-dominant autoflower strain.

Indica plants have a naturally fuller crown that's best suited for SOG.

2. Avoid Male Plants. 

Likewise, you want to make sure your Indica-dominant seeds are female-bred seeds.

Male plants tend to disrupt the grow space. 

3. Use Small Containers for Planting. 

Anything around the size of 1-3 gallons is ideal for keeping cannabis plants small and manageable.

4. Give Plants a Nutrient-Rich Medium.

Things like amended soil or hydroponics will fuel rapid growth. Supplemental CO2 can also boost photosynthesis in the grow area.

5. Use High-Intensity Lighting.

Lights like LEDs or HPS/MH can penetrate the canopy and produce dense buds.

6. Train Plants Aggressively.

Use techniques like training, pruning, bending, and tying down to optimize weed plant shape and size.

7. Remove Lower Growth Shaded by Canopies.

This will help the plants focus energy on top cola sites. 

8. Group Cannabis Plants with Similar Vigor.

This will allow for even flowering and maturity. 

9. Control Temperature & Humidity.

This will help prevent issues like mold. Use fans for air circulation to prevent pests or diseases, too. 

10. Control Water.

Remember that this is a crowded setup, so you need to stay on top of the watering to optimize a healthy grow.

Why the Sea of Green Method Works Well for Autoflowers 

The Sea of Green technique lets you get the most buds using the least space.

Growing many small plants close together instead of fewer bigger ones means you can harvest more buds while taking up less room in your grow area.

And since the plants are small, they need less light, water, and nutrients. Over time, this method saves money and resources for the grower.

Here are some other benefits to the SOG method - and why it works so well for Autoflowers in particular:

  • Efficiently uses small indoor space to maximize harvests
  • Allows continuous growing all year by staggering plantings for perpetual production
  • Saves energy costs by needing fewer lights and faster autoflower growth
  • Speeds up harvests since Autoflowers skip the veggie stage and flower quickly
  • Requires less training/pruning than photoperiod plants
  • Works well for organic growing and living soils to improve bud quality
  • Produces uniform, high-quality buds by focusing energy on the tops 
  • Eliminates lower, less desirable buds with tight spacing
  • Allows organic auto-flower grows with living soil options

Frequently Asked Questions

What type of cannabis strains are best suited for the SOG method?

For the Sea of Green method, we highly recommend choosing auto-flowering and mostly Indica-dominant cannabis strains.

Autos flower fast no matter what, while Indicas stay short and bushy instead of stretching out. Both characteristics are ideal for the SOG technique.

Some great strains are White Widow, Northern Lights, and Girl Scout Cookies.

Other strains that naturally stay small and thick work best as well. These compact plants will let you pack more into your grow space.

Can You Use the SOG Method on Non-Autoflowers?

Yes! The original Sea of Green technique was designed for growing regular, non-autoflowering cannabis strains.

With photoperiod plants, SOG focuses on keeping vegetation time short, switching to 12/12 lighting faster to induce flowering. This avoids tall, lanky plants.

For non-autoflowers, you just need to trigger flowering since they won't mature on their own.

SOG works well to get more out of traditional strains through efficient use of space.

When should I start the flowering phase in a SOG grow?

With Sea of Green, you start flowering way earlier than usual - this keeps the plants short.

For regular strains, flip the lights to 12/12 when your plants are around a foot tall.

That's just 2-3 weeks after sprouting them. For autoflowers, you don't need to change the lights.

They'll start making buds on their own in 2-4 weeks. You just let them do their thing and stay small.


Implementing the Sea of Green (SOG) method with autoflowering strains allows growers to produce greater yields in limited spaces.

By focusing on growing many smaller plants densely packed, the SOG system keeps vegetative time short and flowering perpetual.

If you’re looking to optimize your grow space using this method, you might consider where to buy autoflower seeds from USA to ensure you get high-quality genetics suitable for SOG.

Hopefully, this complete guide helps you and encourages you to try the Sea of Green method for yourself!
