If you are looking for a classic, then White Widow is an interesting choice. Both the end product of the plant and the development of the plant are very powerful. Although the plant contains 50% Indica and 50% Sativa genes, the plant remains small sized. However, the harvest isn’t disappointing. Certainly not when you apply the SOG method. You can expect yields of up to 550 grams per m2.

Best seeds for Sea of Green method

If you are looking for the best seeds for Sea of ​​Green method we advise you to read on.

The SOG or Sea of ​​Green is, as you probably know, a targeted method to grow many plants together in a limited space with the aim of achieving an accelerated cycle and higher yields. You will therefore not be surprised that many commercial growers use this method. However, also small home growers can benefit from this method.

What you may not know is that not all species are suitable for the SOG method. Especially because the plants are standing close to each other and some species need space to develop in a healthy way. It’s therefore important to choose a species that meets the requirements for a Sea of ​​Green which start by choosing your cannabis seeds.

A sea of ​​green cannabis plants is a dream for many growers. For others it’s a dream that will become true soon. Do you want to be sure that your plants can be grown in an SOG setup? We have created a top 5 with the best seeds for Sea of Green.

Top 5 best seeds for SOG grow

Before a grower chooses his SOG seeds he will first calculate the number of seeds required. In this calculation, a germination percentage of 90% must be taken into account. For example, growers who want to grow 10 plants will need 11 seeds because probably one seed won’t germinate (cannabis seeds remains a natural products).

In addition, the Sea of green seeds have to be the same species and it’s advisable to choose an Indica type. Indica’s naturally remain small sized and grow mainly in width.

Choosing your SOG seeds

Now you can calculate the number of required Sea of ​​Green seeds and what you need to take into account, it’s time to select a strain. If you are looking for the best plants for sea of green and want to be sure that your strain is suitable, it’s advisable to choose a strain from our top 5 with the best marijuana strains for Sea of Green.

Somango XXL

A variety that is very suitable for the SOG method is our Somango XXL. This Indica dominant strain is in fact easy to grow, remains small but produces good harvests. Especially with the Sea of ​​Green method. Yields that can be expected are between 525 and 625 grams per m2.

White Widow

If you are looking for a classic, then White Widow is an interesting choice. Both the end product of the plant and the development of the plant are very powerful. Although the plant contains 50% Indica and 50% Sativa genes, the plant remains small sized. However, the harvest isn’t disappointing. Certainly not when you apply the SOG method. You can expect yields of up to 550 grams per m2.

Northern Lights

If we are talking about classics that are suitable for the Sea of ​​Green method, Northern Lights can’t be missing. This strain contains all the qualities that are important for a Sea of ​​Green. A small sized plant, easy to grow and a flowering time of just 56 days. With the SOG method the plants will produce high quality yields that can reach up to 550 grams per m2.


As a predominantly Indica strain with yields that can reach up to 600 grams per m2, the Critical is one of our best yielding strains for sea of green and couldn’t be missing in this overview. Critical is a small plant with a flowering time of just 59 days. Although the plant is slightly more sensitive to fungus, this species is easy to grow.


Sometimes people say: “Save the best for the last”. Although the Cheese is loved and hated because of its pronounced taste, this strain had to be listed in our top 5. Thanks to its 50-50 ratio of Indica-Sativa, the Cheese is slightly larger than for example the Critical. However, the strain is still very suitable for the Sea of ​​Green method. Especially because of the high quality yields that can reach up to 600 grams per m2 and the ease of cultivation.

Sea of Green (SOG) – Harvest more, faster

Sea of Green Growing cannabis is surprisingly simple: all you need are a few seeds, pots, water and light. If, however, you want to maximise yields and also save time, you will do best with a Sea of Green. No other growing approach will allow you to harvest so much in so little time.

The pioneering spirit of the Dutch is the stuff of legends. Want some examples? The telescope and the microscope, stock exchanges, Fairtrade, CD’s, Bluetooth are all Dutch inventions. It was also the Dutch who developed a new way of growing cannabis in the 1970s, which would change commercial growing forever.

We are talking about the Sea of Green method, which combines two major benefits: maximum yields and minimum time invested. Sound too good to be true? Not at all! With a few simple tips, any keen gardener can successfully grow cannabis.

Sea of Green

The cultivation of cannabis indoors presents the grower with the same challenge every time: how do you make best use if the (limited) space available and how do you ensure that the plants get as much light as possible? The answer: Sea of Green.

This approach to cultivation uses a lot of small plants, instead of a few large plants. The growth phase is deliberately kept short, so that the space is completely filled and the light efficiency can be maximised.

Which cannabis varieties are suitable for a Sea of Green?

It is important to use a suitable variety of cannabis and the best idea is to use clones from a single parent plant. This will ensure that the plants all grow in the same way. Growing identical plants for a short period is the main key to success with a Sea of Green.

If you prefer to use cannabis seeds, then make sure they are all of the same variety. Sativas tend to grow too lanky and would impinge on the other plants, but Indicas are more suitable.

The following varieties are particularly appropriate for use as a Sea of Green: Super Skunk, Afghani #1, Hindu Kush and because it is very robust, the classic Northern Lights as well.

Auto-flowering cannabis varieties shift automatically to the flowering stage within a few weeks of germination. They are a popular choice for a SOG. On the other hand, auto-flowering seeds tend to develop a branch structure with a wide reach. In addition, because of their Ruderalis genes, they will never develop buds as large and potent as those from seasonal cannabis.

Going from growth to flowering phase

The ideal pot size is around 15 cm, holding 4 to 6 litres. This means the plants will be fully mature at a height of 30 to 50 cm.

Anyone living in a small apartment, or working with a Micro Grow Setup, will understand the benefits offered by only needing a small vertical space. Experienced growers can even use shelves to stack several growing levels on top of each other.

A common mistake is to assume that the pots need to be placed as close together as possible. This creates a seamless plant surface area, which initially sounds like a great idea. But what this actually means is that the plants are competing directly with each other, with the result that they try to outgrow each other. This “jungle effect” causes stress for the plants, which in turn leads to less biomass or less bud formation.

It is better if the plants do not initially touch each other. The ideal timing for a Sea of Green is not during the first one or two weeks of the vegetation phase, but instead from about the fourth week of the bud formation.

Once the plants begin to grow visibly and the first leaves have appeared, then the seedling phase is over.

Opinions differ as to how long the vegetation phase should last. There are growers who trigger the flowering phase after just a few days, but it is better to wait 10 to 14 days before doing so. The plants are still very young at this point.

If you then change the light cycle to 12 hours of light and 12 hours of darkness, the plants will devote all their energy to creating one main bud. Now is the time to check that the light sources are hanging high enough to avoid creating any hot spots. Incorrectly placing the lamps is one of the most common errors in the cultivation of cannabis.

Uniformity is the answer

Proper care is everything when it comes to successful SOG cultivation. All the plants must be treated equally. This applies to the lighting and supply of nutrients, as well as watering and pruning. Drip systems have proven useful, because they ensure that all plants receive the same quantities of water and nutrients.

It is worth carefully pruning the plants during both the vegetation and flowering stages. If you remove the lower branches, then the plants have more energy to put into forming buds. The goal is for the plants to put all their energy into forming the main bud.

Superfluous leaves and spindly side branches should be removed during the flowering phase. A welcome side effect of this is that it improves the circulation of air.

Important: Great care must be taken with any intervention on growing plants! If you remove too many leaves or branches at once, you run the risk of the plants going into shock and ceasing to grow normally, or producing fewer buds.

Quick summary of the pros and cons of Sea of Green:

+ maximum yields in minimum time

+ multiple harvests per year

+ multiple layers growing above each other

+ not much vertical space required

+ very well suited for commercial growers

+ particularly well-suited for Indica varieties

– Indica and Sativa varieties cannot easily be combined

– more time needed to tend the plants (large number of plants)

– because a large number of plants are needed, you may end up breaking the law

– pests and diseases can spread very quickly

The perfect method of cultivation? There is no such thing!

Every growing method has its pros and cons. Depending on where you are, the available space, equipment, experience, and not forgetting personal preferences, one method or another may be best for you. Getting your hands dirty beats book learning here. It generally takes a few test runs before you master any particular approach to cultivation.
