SoG setups are sometimes popular with those growing many auto-flowering strains since these strains cannot be trained with most of the traditional plant training methods.
SoG is how you achieve plants that look like the one below at harvest (why was this plant defoliated?)
Flowering was initiated right after the above picture. Here are those same plants a little over a month later, after they’ve started making buds.
For this grow style, growers usually switch to the flowering stage when plants are around 4-6 weeks old. Plants switched sooner than 4 weeks may not have enough time to get the most out of an SoG setup. Adding an extra week or two of veg, so each plant gets bigger can make a pretty big difference in yields too, so it’s about finding that balance between getting to harvest as quickly as possible versus harvesting a lot of bud.
These five auto-flowering plants started at the same time in this DWC setup. Without any training or special time schedules, they grew into this at harvest!
For SoG, wait to switch to 12/12 until plants are this size or bigger (note: young plants like this can and will double or triple in height after the switch to 12/12).
These plants were in the vegetative stage for about half as long as the plants in the previous picture, AND they had significantly higher yields!
Note: To add another confusing term into the mix, ScrOG (Screen of Green) is something completely different, and involves using a screen to grow a flat canopy of buds. A lot of names for common cannabis growing techniques don’t necessarily seem all that well thought out 😉
“Sea of green” is the idea of growing many small cannabis plants instead of just a few bigger plants. The advantage is that you can get to harvest more quickly because each plant doesn’t have to get nearly as large to support the same total number of bud sites. If each plant only needs to get half as big, it takes much less time to harvest!
This tutorial shows you how you can use the practice of growing many small plants to increase your yields and get to harvest more quickly!

Any training technique combined with any growing method or substrate in the first place requires happy and thriving plants. Incorporating best practice plant care means vigorous and healthy plants at each stage of growth. There are a number of growing techniques that can be used to maximise space efficiency during growth and to increase harvests. However, no technique will help if plants aren’t vibrantly full of life to begin with.
SOG: Cultivars that tend to naturally produce a dominant central cola with minimal lateral branching are often used. Indicas and indica-dominant hybrids have this feature as part of their morphology. Once plants are of a certain height, usually 20–30cm tall, the 12-12 flip to the bloom cycle is made. Plants develop almost entirely as a single cola with lateral branches being reduced to single buds. Some individuals will initiate the entire grow starting from 12-12 so that only small plants develop.
Using the right pots for your SOG or ScrOG garden is super important to ensure the health of your plants and the best possible yields. As a general rule of thumb, you’ll never want to grow using pots of less than 3–4 litres, but keep reading for a more detailed look at what pots to use for SOG and SCROG.
Screen of green is a plant training method with the same goals as SOG—to increase the yield per square metre at harvest time as much as possible. Larger pots are used to accommodate larger root zones for larger plants. Many flower sights are encouraged by bending and holding new growth horizontally. Even light distribution over a literal screen of green fills an entire grow room with fewer plants that have an abundance of homogeneously sized flowers.
Strain selection plays its part for efficient use of space.
ScrOG: Cultivars that naturally produce lots of bud sites take well to this technique. Sativas or sativa-dominant strains that have a lot of nodes have this feature as part of their morphology. These normally tall and branchy strains, whose lower buds may not develop fully if left to grow untrained, get light exposure to all the bud sites, which encourages larger bud growth. It isn’t absolutely necessary to grow sativas this way, as indicas respond just as well.
When growing 9–12 plants per m², you’ll be restricted to using pots with a diameter of between 20–30cm, which typically have a capacity of 7–11 litres. Using pots of this size is fine, but keep in mind that you’ll only be able to veg your clones for about 8 weeks without them becoming rootbound and stressed from the lack of space. If you want to keep your plants vegging for longer, you’ll need to invest in larger pots.
