How to Grow Cannabis with the Sea of Green Method: A Comprehensive Guide

Grow Cannabis with the Sea of Green Method

Growing cannabis at home can be a fun and rewarding experience, but it can also be intimidating if you don’t have the right tools and knowledge. That’s where the Sea of Green (ScrOG) technique comes in. ScrOG is a popular growing method that maximizes yields and minimizes the amount of time it takes to grow cannabis plants. In this article, we’ll go over the basics of ScrOG and give you a step-by-step guide on how to set up your own ScrOG at home.

ScrOG stands for Sea of Green, a growing method involving training cannabis plants to grow horizontally under a mesh screen. ScrOG is popular because it maximizes the light that reaches each plant, leading to bigger yields and healthier plants. Compared to other growing methods, ScrOG requires less space and is more efficient.

What is a Sea of Green (ScrOG)?

What is a Sea of Green 1
ScrOG is a method of training cannabis plants to grow horizontally under a mesh screen. The plants are trained to grow through the holes in the screen, allowing more light to reach each bud site. The screen is typically placed about 12-18 inches above the base of the plants. The goal is to create a canopy of buds at the same level, maximizing the amount of light each plant receives.

The science behind ScrOG is fairly simple. By training the plants to grow horizontally, you’re allowing for more light to reach each bud site. This leads to bigger yields and healthier plants. The horizontal growth pattern also helps create a more even canopy, which can help prevent mold and mildew.

Not all cannabis strains are well-suited for ScrOG. Generally, strains with a more even canopy that don’t grow too tall work best. Indica and Hybrid strains tend to work well, while Sativa strains can be more difficult to train.

Equipment and Supplies Needed

To build a Sea of Green, you’ll need the following equipment and supplies:

  • Mesh screen
  • Grow tent or grow room
  • Grow lights
  • Grow medium (soil, coco coir, hydroponics)
  • Nutrients
  • Fans
  • Pruning shears

You can find most of these supplies at your local hydroponics store or online. Make sure to do your research before purchasing any equipment to ensure that you’re getting high-quality products that will work well for your ScrOG setup.

Setting up Your ScrOG

Once you have all of your equipment and supplies, it’s time to set up your Sea of Green. Here are the steps to follow:

  1. Install your mesh screen: Hang your mesh screen about 12-18 inches above the base of your plants. Make sure the screen is level and secure.
  2. Choose your grow medium: Decide what type of grow medium you want. Soil, coco coir, and hydroponics are all popular options.
  3. Plant your cannabis: Plant your cannabis seeds or clones in your grow medium.
  4. Train your plants: As your plants grow, gently train them to grow through the holes in the mesh screen. Use pruning shears to trim any excess foliage that is blocking the light.
  5. Adjust your lights: Make sure your grow lights are positioned correctly to provide adequate coverage for your ScrOG setup.
  6. Monitor your plants: Keep an eye on them and ensure they’re growing evenly. Adjust the mesh screen as needed to create a more even canopy.

Once your Sea of Green is set up, it’s time to start growing your cannabis. Here are some tips to help you get the best results:

  1. Water your plants regularly, but don’t overwater them.
  2. Use high-quality nutrients that are specifically formulated for cannabis plants. Follow the manufacturer’s instructions for dosage and application.
  3. Keep your grow room or tent at the optimal temperature and humidity levels for your plants. This will vary depending on the strain you’re growing, so do your research and adjust as needed.
  4. Use fans to provide adequate air circulation and prevent mold and mildew from forming.
  5. Monitor your plants for signs of pests or disease. Catching problems early can prevent them from spreading and damaging your entire crop.
  6. Continue to train your plants as they grow to ensure they’re growing evenly and maximize light exposure.

Harvesting Your Cannabis

Once your plants have reached maturity, it’s time to harvest and dry your cannabis. Here are the steps to follow:

  1. Determine when to harvest: Look for signs that your plants are ready to harvest, such as the trichomes turning cloudy or amber. Harvest when the majority of the trichomes are cloudy.
  2. Cut down your plants: Use pruning shears to cut down your plants at the base.
  3. Trim your buds: Use scissors or shears to trim off any excess leaves or stems from your buds.
  4. Dry your buds: Hang your buds in a dark, dry place with good air circulation. Check them regularly and adjust as needed to prevent mold or overdrying.
  5. Store your cannabis: Once your buds are dry, store them in an airtight container in a cool, dark place. This will help preserve their potency and flavor.

While ScrOG is a relatively easy-growing method, there are still some common problems you may encounter. Here are some troubleshooting tips:

  • If your plants are growing too tall, adjust the height of your mesh screen to encourage more horizontal growth.
  • If your plants develop mold or mildew, increase air circulation and reduce humidity levels.
  • If your plants show signs of nutrient deficiencies, adjust your nutrient regimen to provide the necessary nutrients.


Sea of Green is a popular growing method for cannabis that can help you maximize yields and efficiency.
