Sea of Green (SOG) or Sea of Green
Do you have only limited growing space available and want the largest possible harvest? It has been some time since Dutch growers came up with this simple, effective, and therefore now widely used growing technique, which makes indoor herb cultivation in a growbox easier and more efficient. Let us take a closer look!

What is the basic principle of the SOG plant growing method? Simply shortening the vegetative phase of the plant to the necessary minimum and bringing on the flowering phase more quickly in order to make maximum use of the space in any indoor growing room.
Right from the start, let us set out three reasons why it is worth learning the SOG growing method:
- Regular and overall higher yield.
- Low height requirements, meaning more plants in a limited space!
- Earlier harvest, as plants are usually in the vegetative phase for only two weeks, often even less. Short-term growing also reduces the risk of plant diseases or pests.
Now let us explain how to do it:
- With this method, clones or cuttings are planted rather than seeds. (How do you recognise a quality clone? Read HERE.) For a sea of green, varieties with the shortest possible flowering time and lower expected height are selected.
- Plant your favourite plants so that each has ideally at least 30 x 30 cm of space. Practical and aesthetic considerations tell us to use smaller square pots.
- Using an LED lamp or light from a discharge lamp, give the plants 18 hours of light per day until they reach a height of between 25 and 30 cm.
- Then change the light cycle for a rapid start to flowering, i.e. 12/12. If, with regard to a specific variety, you do not want to limit yourself to the recommended plant height (see above) for this step, you can also use the age of the plants as a guide. At this point, your plants should be no more than three weeks old, but usually rather only two.
- As a result of the previous steps, a typical canopy of flowers will form during the flowering phase. This also ensures maximum use of artificial lighting.
- Use good-quality, clean scissors to trim all branches below the canopy of flowers.

Our TIP: By using a hanging structure, you can grow plants with this method above one another as well, making even better use of the space in the growbox or growing room. It does require a bit of DIY spirit, but it is worth it!
- Bear in mind that with this indoor cultivation method, a quality light source is even more important than ever, as it does most of the work. For repeated harvests, it will certainly pay to invest, for example, in LED grow lights from the Lumatek brand.
- The rest is taken care of by quality ventilation equipment, which removes excess humidity and heat from the growing space.
If you plan to harvest flowers or crops repeatedly thanks to this method, we recommend buying really high-quality equipment straight away, with the price-to-performance ratio in mind.
