Sea of Green (SOG) Marijuana

Sea of Green Growing Marijuana

What is Sea of Green?

Sea of Green, or SOG, is a method of growing cannabis that forces the plants into the flowering stage  when young and small. By starting the flowering phase of your marijuana plants after about two weeks of vegetative growth you can harvest many weeks earlier than you would if you grew your plants to full size.

Why Choose Sea of Green?

The Sea of Green method is a Dutch concept and is all about using space efficiently and is particularly useful if you are limited with the space available in your grow room (although it is also often used in large operations and greenhouse grows as well). By switching the cannabis plants’ lighting to 12/12 early (to force flowering) it is possible to fit several plants in the space normally taken up by one plant. Even though the yield of each individual plant is smaller, the accumulated yield per square metre will be greater.

Time is also an important factor to consider when deciding whether to use the Sea of Green method. Some marijuana strains can spend well over 10 weeks vegetating so by putting your marijuana plants into flower after only two weeks you will get more harvests per year. This is ideal for larger operations where a constant supply is necessary.

When growing BIG marijuana under artificial grow lights it is important to use the light in the most efficient way possible. Not just because you’re paying for its electricity; but because you will want to get the most from your plants too. Most grow room setups involve lighting your plants from above but doing this means that the plants shade out their own bases and the lower sections of the plant do not receive as much light as the tops. By packing the plants together a canopy of buds is formed, making best use of the light. If you are using one big HPS grow lights then you only have the option of lighting from above, using a number of HPS grow lights or better still energy saving full spectrum LED grow lights then you still have the option of lighting from the corners.

The Sea Of Green method is particularly useful if you have a quantity of cuttings available from cloned marijuana. This method saves you money on buying seeds and can ensure the quality and gender of the young plants. Although Sea Of Green doesn’t generally require any pruning, once a canopy has formed some growers like to clean up the branches underneath to concentrate the plants’ energy towards the main bud and improve air flow beneath the canopy. These cuttings can be cloned and will provide the next batch of SOG plants, making a self perpetuating system.

How to use the Sea of Green method

There are no special skills required to use the Sea of Green method. Once you understand the concept, carrying out an SOG grow is simplicity itself. In fact, with the absence of any training or pruning requirements, SOG is one of the easiest ways to grow weed.

Here is a simple Sea of Green step-by-step guide:

Some growers will start plants on 12/12 when they are only 6 inches high, others pack them more or less densely. Exact requirements will vary from strain to strain and grow room to grow room. If you use this guide as a starting point you will be able to make adjustments based on your own experience.

 

Which seed strain – Are all marijuana strains suitable for S.O.G?

The short answer is no. Typically indica seed varieties, with their naturally squat stature and single main kolas are most suited to S.O.G methods. Some sativas may work but they are generally too ‘leggy’ to fully benefit from SOG systems. We would recommend Old World Indicas, Kush strains, God Bud and Northern Lights. Also try some of the more specialized feminized dwarf strains such as Buddha Red Dwarf Autoflowering Feminized  and Royal Queen Royal Dwarf Autoflowering Feminized.

  3. With the SOG do you need to change how you fertilize? Using all organic and was worried that the plants might not get all they need with a smaller root structure.

    • Shouldn’t really make a difference Joey. For sure, you will not have to feed as much as you might some monster sativa that is 12 feet tall, but there is no special rules for SOG feeding. Feed as you normally would.

  4. .if you have no led or cfl lights can you use a cheep lamp at night and a window in the day? and if not then will it hurt them to skip the 24 hour light and go straight to the 12/12 lighting. also these are just mid seeds from a street dealer. will the SOG method work on them? also how can I hide the smell? and if I cant then can I put them outside after winter? and one more thing, how long will it be until I can harvest using the SOG method? I know I have a lot of questions but if anyone can help id be greatful!!

    • with plantS (plural) grown in soil….. Simple answer is yes. Try joining our forum (link at top of page) to chat with other growers and get more specific answers to your questions.

    • Sea of Green method is specifically for multiple plants. The theory is that you keep lots of plants small and the canopy is more productive than a standard plant given the space. It is a method for getting the most production possible given a set time and space. Admins answer is good, you obviously have a lot of questions, join the forum where you can get better answers to each of them, as well as ongoing support and friendship from other growers.

  7. Hi Emolta
    Noticed your comments about LEDs. The forum connected to this site now has a resident LED expert to answer any of your lighting questions. Why not post any LED specific questions there and see what he has to say….

  8. Hello.

    Nice guide written above.

    I’m about to start an aeroponic system in a closet, got all the gear, tubes , pumps etc.

    The closet i have available is around 180 cm in height, and my plan is to devide that into two grow spaces. Probably lower space for vegetative and upper for flowering. Does that sound reasonable enough or do i need more height?

    Will you recommend LED grow lights? I like them because they save money on my electricity bill, but if they’re inefficient it doesn’t matter. Also they seem to fit into small spaces.

    If i understand correctly, in the vege state you only need about 30 cm for the plants + abit for reservoir and lamp, but do they grow taller in the flowering state?

    Going to use some Mylar-ish stuff on the insides of the closet by the way.

    Looking forward to hopefully getting a good reply. Thanks in advance.

  9. Hi B
    Mirrors are very inefficient at reflecting light. I know that sounds mad but it’s true. They reflect light unevenly and create hotspots which may damage your plants.
    Unless you can get hold of a product made especially for the job (such as mylar) then the best way to reflect light back into your plants is to paint the inside of the closet matt white. It might not seem as brilliantly shiny as the mirror but it keeps the light bouncing around in a nice evenly distributed way.

  10. Has anyone tried using mirrors on the walls on an inside operation to reflect light? I want to grow in a closet and the idea came to mind to make the best use of the light.

    im confused it mentions taking clones from sea of green which will be on 12/12,i was under the impression you only took clones from plants in veg state 18/6 .am i right or wrong?”
    you are correct if you dont want to shock your clones but it is possible to take flowering clones and revert them into vegging

  13. Hey Merlin
    I think it’s just the way it’s written. You can take clones from your SOG set up before it goes onto 12/12. It’s just a way of turning your cuttings into something instead of trashing them.
    You are right. clones should be cut from vegetating plants.

  14. ok I plan to be a doctor and a friend and I were talking about medical marijuana.
    I think that if a patient was suffering from a condition that they thought that marijuana was helping than it would be ethical for me to prescribe it for them. And unethical for me not to.
    What do you think should guide the decision for a doctor to prescribe marijuana? BTW I don’t smoke marijuana. And I want to be responsible.slicktop80 thank you. What you say is a good example of what I am thinking.I don’t have a strong opinion against recreational marijuana use for Adults but abuse..I mean heavy use.. is damaging and it bothers me to see people become toast.Oh and I’m happy to hear of your remission and best wishes for your recovery LOL LeighAnnD! Maybe you would like to volunteer as a research participant?
