The SoG Growing Method Explained

cannabis sog

Sea of Green or SoG is a popular and efficient cannabis cultivation method for indoor growers that allows them to quickly grow a large number of smaller plants instead of a single or a couple of bigger ones. Therefore, Sea of Green results in large harvests of dense buds using a minimal amount of space.

This technique originated from the realization that the best buds in a plant are those that are closest to the light – the lower part of a plant tends to yield a sizeable amount of smaller, airy flowers that don’t get the chance to fully develop. While there’s nothing wrong with these, they don’t compare to those found closer to the top of the plant. The purpose of SoG is to create a flat canopy of tops with high-quality buds only, while also benefitting in terms of the harvest size since growing lots of small plants is better than having fewer big plants.

Pros And Cons

While there is a full range of advanced cultivation options out there such as lollipopping and monster cropping, no technique can replicate the yields and quality of cannabis associated with SoG. This technique is for growers who want to get as much as possible from an often small indoor growing space. Whether this is a closet, a tent, or an entire room, SoG allows growers to stretch each square foot further! Here are some pros and cons of SoG:


  • A short grow cycle
  • Improved quality of harvest (more plants means more tops)
  • More efficient use of lighting and space


  • If the legality of cannabis is an issue where you reside, it may not be a good idea to have lots of cannabis plants
  • Pests and diseases can spread easily and quickly
  • It’s preferable to use only one strain for the whole SoG grow

How To Make Your Own Sea Of Green

If you’re an indoor grower (and even if you grow outdoors), there’s no reason why you wouldn’t want to try out the Sea of Green method. Stick with us, because we’re starting to explain the process, from choosing the source of your plants to actually implementing them into a Sea of Green setup.

First, Choose the Source of Your SoG Plants

SoG grows can be done with multiple plants grown from multiple seeds, or by taking clones from a mother and taking these forward to flower. Next, we’re going to explain the pros and cons of each method.

Growing From Clones

Cannabis strains have variations between seeds that cause differences in the smell, taste, appearance, and growth patterns of the plant (known as phenotypes). When growing using Sea of Green, it’s important that all plants are of the same height and have predicable grow patterns, and the best way to achieve this is to take clones from a promising mother and grow these for 12-16 days before flowering.

Growing From Seeds

Growing from seeds is the most straightforward of the two methods. Kicking off your SoG grow this way involves germinating a seed and planting as you normally would, although in greater numbers. One of the downsides to this is the high cost of cannabis seeds. However, there’s also a lot of time saved in not having to grow a mother plant and waiting for clones to mature.

Once your plants/clones are ready, transfer them into larger pots (5-11 L is the sweet spot) and grow them for a further two weeks before switching to a shorter photoperiod and inducing flowering.

Sea of Green Step by Step

Step one: Germinate the seeds of the same strain or create clones from a mother plant in your desired amount. It’s always better to germinate more seeds and take more cuttings than the number of plants you want to grow using Sea of Green, because there’s always a chance that some seeds won’t sprout or a clone doesn’t root.

Step two: Plant the seedlings/clones as usual and place them under the lights for 18 to 24 hours a day until they reach 10”-12” (25-30cm) in height. Depending on the vertical space you have available in your grow room, you may also grow them until the plants only reach 6” (15cm) in height. Remember, after the switch to 12/12 and the start of flowering, the plants in your Sea of Green setup will continue stretching.

Step three: Change the light schedule to 12/12 in order to force your plants to start flowering.

Step four: Cut the underlaying branches off after you see that a dense canopy has formed. You can let them root as clones to use in the next Sea of Green grow!

Step five: Once the buds are ripe, harvest, dry, and cure!

These steps can be repeated again with the clones you took during step four.

Which Strains Are the Best For SoG?

The ideal strains for SoG growing are those that remain relatively short, respond well to pruning, and have a predictable growth pattern. When creating a Sea of Green, it’s important to get this right from the start! While the strains listed below all have very steady and predictable growth patterns, each has its unique strengths as well. So, what are the best cannabis strains for SoG?

Important Details of a Successful SoG

As the goal with SoG is to grow a large number of small plants rather than a smaller number of large plants, it’s important to get the number of plants per square foot right from the start! You don’t want to overcrowd your grow space, but at the same time, it’s essential to maximize the usage of light. As cannabis strains don’t all grow the same, there is no single correct number of plants for an effective SoG. Depending on how much space you have to work with, you might be able to get away with more, although one plant/ft2 is a good rule of thumb. SoG grows tend to have a quicker vegetative period than traditional growing methods, which is without doubt one of the biggest benefits of this grow technique.

I'm going to try 12/12 from seed with three stains in a 12 plant sog, using 1 1/2 gal Mass Producer coco buckets. Does anyone have experience with sog and/or 12/12 from seed?
thought that 12/12 from seed didn't work? Like it wont flower for the first 4 weeks regardless? I would do 20/4 for the first few weeks and then go to 12/12
SOG, SCROG, whatever, I can’t wrap my head around this! Still growing everything the old ways, seems to work. Maybe if I was doing it professionally I would try harder
Hi, miss7drunk, growing "old ways" is always good, at the same time you may discover new features and achieve much more yield trying this method.
I was trying to get an idea on how to do a sog setup with a 4x4 tent using a 1000hps. I would like to pull a pound a month if possible but I think I will need more to this setup than just one tent can anyone help me out?
Hello hoobear, If you require more info about cloning, you may find this article useful: https://herbiesheadshop.com/blog/how-to-clone-cannabis-plants
get a good SOG strain, something with Skunk and some sativa in it, make a soil bed in there out of wood and a table.. 4x4 and 16 inches deep.. if done right you should have access from all sides.., put 16 clones, 1 per sq ft, veg 10 days then flip, add CO2 and get a good foot and a half distance between hood and plants.
So if I get this correctly… the point of SOG is to fit as many plants in as tight of an area… I personally had too many problems in my day with molds of all sorts… wouldn’t they ultimately ruin a Sog op? Too much work to keep an eye on proper air circulation
I'm planning a SOG grow very soon, will be using a 600w HPS in a 100cm Dia. Parabolic Reflector, plan to grow Orange Bud. Not sure what pots to use. Looking at these 11 litres square pots (https://greenshydro.co.uk/11l-litre-pots). Is 11 litres enough? They're 26cm sq so would I fit 16 under it or is that too much n should go for 9? Cheers
11l will be the final pot though? they are big enough I am sure
