SCROG vs SOG: What Is Better For Your Autoflowers?
Scrog vs Sog is one of the most asked questions by many growers indoors. These are two different techniques that even being so different both give a solution to the same problem: to increase cannabis yields and quality per crop.
1. What is SCROG and SOG?
SCROG and SOG are both low stress training (LST) techniques used to control the growth of cannabis plants. This is done by creating a horizontal even canopy, this ensures all bud sites receive light uniformly and grow at the same rate.
Usually, the lower branches can’t absorb much light and don’t develop well. These techniques were created to focus on the top part of the plant, producing big colas and denser buds in less time.
The Screen of Green (aka SCROG) is a type of low stress training involving a net screen between the growing lights and pots and little bit of plant training.
In this method, the cannabis plant will eventually grow up to the net screen and with a bit of training achieve the desired objective. T he training needed after they reach the net is relatively easy, you just need to push the branches that have outgrown the net back down, this will make the branches grow horizontally and slowly create a large and even canopy.
This is an excellent way to take full advantage of the area covered by your lights, by training your plants into a spread out canopy you allow multiple bud sites to develop to their full potential instead of one large one at the top.
Once the canopy is established, most growers prune all the lower growth as they are in the shadow of the canopy thus not getting light, this way you avoid wasted energy.
An important factor to take into account when using the SCROG technique is the strains being used. Depending on the genetics, cannabis plants can react differently when switched over to a flowering photoperiod, some will stretch and rapidly fill out while others won’t.
This is a good method if you want to make the most out of every seed, generally using 1 plant per 30 cm of net.
The main difference between SCROG and SOG is that in the Screen of Green you will use way fewer plants to fill the canopy than in the Sea of Green.
Where in SCROG you may need up to 4 plants per m², in a SOG you can have 12 or more per m², depending on the type of strain.
• It can be done with cuttings and seeds.
• Offers multiple bud sites from only a few plants.
• Low maintenance as you only have a few plants to take care of.
• Takes longer than SOG.
The Sea of Green (aka SOG) is especially used in small grow spaces or when you want to grow your plants really fast and you can (or not) use a net to help you maintain the plants short.
Where the SCROG technique focuses on producing multiple bud sites, the Sea of Green technique does the opposite, forcing the cannabis plant to put all its energy into one main cola.
Unlike SCROG, the SOG technique is recommended to be done with autoflowers or clones.
To grow in a Sea of Green, plants are packed into a tight space reaching up to 40 or more per square meter.
Even though there are strains that may take more time, after giving around 2 weeks for clones you should switch to a flowering cycle so they can flower while still being short, producing a thick stem and branches.
This growing method does not require pruning or trimming as long as you have proper airflow. When growing a large number of plants together it is recommended to add fans to not only strengthen the stems to allow your plants to not fold down but also reduce the risk of pests and diseases.
For autoflowers it is recommended to use a net, after 3-5 weeks of growth and slight training the net should be completely filled and ready for the production of flowers.
There are strains that are better well suited for this kind of grow method, generally, Indicas tend to be most suited to this. Plants should rarely grow beyond 30cm tall using this method, so all energy is in the main cola.
The way plants need to grow in this method is why you use clones or autos, feminized plants grown from seed will still grow high before they can start flowering.
• Very fast growing time.
• Great for small grow spaces.
• Faster than SCROG.
• A lot of plant material means a higher chance of pests.
4. Which Technique Is Better For Autoflowers?
As we all know, autoflowers don’t take too well training and even LST can shock them if not done properly and even though it is possible to perform SCROG with autos, it is not recommended.
Most autos don’t grow as much as photoperiodic cannabis and it can be really difficult to trim unwanted growth without encountering a lot of problems, that’s why SOG is highly recommended for autoflowers.
It’s better to grow Indica-dominant strains in SOG, we recommend our Girls Scout Cookies Auto as she will naturally grow shorter and if done correctly you can harvest up to 15-20 plants per square meter, resulting in a huge yield per cycle.
Sea of green is considered one of the most efficient methods for harvesting buds from autos as soon as possible. It does not require the training and extended growth time that it takes to grow plants using the screen of green (SCROG) cultivation method. And if you choose proper strains, you can save time and space.
If you want to use a SCROG method on your autoflower, Wedding Cheesecake Auto will be the best option as she performs extremely well under Screen of Green.
Generally, autos grow up to 80cm and need around 3-4 weeks to start flowering, these characteristics that make them unique also make them perfect for growing in SOG especially if you are using a net to control height.
5. In Conclusion
SCROG and SOG are techniques with similar objectives, they help you grow the best quality and yields while making the most out of your lights, grow space, and plants.
If you’re interested in trying them out, have in consideration that the strain you use can deeply affect your final result, try to grow the same strain because if you choose different strains it can get really difficult to train them equally.
Even though it may seem hard, these are one of the simplest techniques with the tips given in this article, and a little bit of experimenting even an unexperienced grower will be able to perform them successfully.

Autoflowers have finally earned the respect they deserve. More importantly, they have earned a place in your grow room. With our guide to achieving maximum yields, you will crop the biggest harvest possible from your autoflowers!
TAKING AUTOFLOWERING CANNABIS YIELDS TO THE LIMIT
Autoflowers grow blazingly fast and don’t rely on light hours to enter bloom. As they make growing weed a lot more convenient, autoflowering strains have become very popular as more high-quality strains appear on the market.
There are several things growers can do to encourage bigger yields from their autoflowers.
1. START AUTOFLOWERS IN THEIR FINAL CONTAINERS
Autoflowering cannabis will race from seedling to stash in a quick 60–90 days. When autos are stressed too much or their growth is otherwise slowed, they will still bloom at the same time, and your yields will suffer.
To max out yield, you should sow seeds directly into their final containers. Alternatively, you can germinate them using the paper towel method (or whatever your preferred germination method may be) and then put them straight into large pots. A healthy root zone must be fostered early.
2. USE BIGGER POTS
The bigger the pot, the more the roots will develop and the bigger your plant will be. If you constrain it in a pot that’s too small, your plant’s development and production will be reduced. It is recommended that you use 15–20-litre pots to maximise results without overwhelming your plants. A pot that is too big will be a waste of substrate and fertiliser.
3. CONSIDER POT MATERIAL
A healthy and strong root system means healthy plants with great yields. Consider “smart pots”, like the RQS fabric pot, to give you an advantage in this domain. With their ability to prevent plants from becoming root bound, fabric pots are better for overall development.
In addition, fabric pots make it nearly impossible to overwater your cannabis as they facilitate excellent drainage.
4. USE AN AIRY GROWING MEDIUM
Autoflowers grow fast and vigorously, and have only a limited time to do so. Because of that, you want to support their growth in every way possible. A loose and airy growing medium makes it easier for your autoflowers to develop a strong root system.
If the substrate is too compact, you can make it suitable for autoflowers by adding some perlite and coco coir. See our article here for more tips on the best soil for your autoflowers.
5. ADD A ROOT STIMULANT
Another way to support root development is by adding a root stimulant. One good way to do this is by introducing beneficial fungi into your growing medium. Mycorrhizal fungi increase nutrient and water uptake, protect plants from disease, and generally encourage an optimal growing environment.

6. START SEEDLINGS INDOORS
Whether you are planning an indoor or an outdoor grow, make sure to start your seedlings indoors.
As you and your plants are on the clock from day one, you want to ensure your seedlings root well. A cool white CFL, appropriate LED, or even a sunny windowsill are adequate. Just make sure vegetative growth goes smoothly; ready or not, your autoflowers will bloom on schedule.
7. SUPPORT PLANT STRUCTURE
Staking or plant support of some kind may be needed to keep your plants upright and their buds healthy.
There are several ways you can go about this. Bamboo stakes and strings, trellis netting, or tomato plant cages can all be used to help a plant carry its heavy load. If you want more tips, see this article on five ways to support heavy buds.
8. OPT FOR 18 HOURS OF LIGHT
Opinions differ on whether keeping plants under a constant 24-hour light cycle is beneficial. 18/6 is still the most common, and will save you money on energy.
Indeed, you could potentially grow them with less light, but we are aiming for a huge harvest, so you’ll want to provide them with as many lumens as possible. More light, more buds. Easy.
When grown outdoors, your autoflowers will thrive in the fine summer weather. Sunlight for 18 hours is not essential because Mother Nature’s grow lamp is infinitely more powerful than any artificial bulb.
9. USE REVERSE OSMOSIS WATER
Your water may be fluoridated or chlorinated, or may contain other impurities that hinder healthy microbial growth in the soil. In short, if your domestic water is unsuitable for drinking, it won’t do good for your cannabis plants either. You can solve this by using reverse osmosis water.
Simply spoken, reverse osmosis is a filtration process that results in pure, ultra-filtered water. With this, you are in total control of the mineral profile of your water. This can benefit the growth of your plants and your yield.
10. DIAL IN NUTRIENTS AND PH
Autoflowers are usually smaller, so they drink and eat less compared to large photoperiod plants. If you’re using ordinary cannabis nutrients, a good idea is to start out with 50% or even 25% of the recommended dose.
Soil growers are advised to use lightly fertilised soil for autoflowering cannabis. Heavily fertilised soils will burn these babies. Aside from supplements like enzymes, vitamin B, and beneficial fungi, autoflowers don’t really require large doses of base nutrients during their short vegetative stage. Heck, with good-quality soil, your plants may do just fine without additional nutes all the way to harvest.
If you must add nutrients to the soil early on, do so sparingly. Generally, bloom nutrients and boosters are all that’s needed during their life cycle. Even in flowering, low to medium doses of nutrients will suffice. Over-fertilising plants is a common yield-thwarting mistake autoflower growers often make.

If the pH is off, your plants can’t uptake nutrients even if they are present. The correct pH for your water when growing in soil is 6.0–7.0. With a few drops of pH up or down products, you can adjust your water to the correct pH window.
11. PRIORITISE CLIMATE CONTROL
Seedlings and young plants prefer a more humid environment, while flowering plants require significantly less humidity to avoid mould and rot.
At times, just a simple standing fan or leaving a window open is all that’s needed to create an optimal growing environment. If that doesn’t cut it, look into solutions such as a heater or air conditioner for your grow room.
12. USE CO₂
It is scientifically proven that plants use CO₂ as fuel for photosynthesis, and with more CO₂ in your grow space, there should be a noticeable difference in growth rate and size.
The thing is, it only makes sense to provide your plants with CO₂ if all the other conditions in your grow room are already optimal. If there are issues with temperature, humidity, water, or nutrients, address these first before looking into a more elaborate (and expensive) CO₂ system.
13. TRAIN YOUR PLANTS
Low-stress training (LST) is a non-destructive training technique that even beginners can use. As the name implies, it is a minimally invasive technique that doesn’t involve any major damage to plants.
All you do is carefully bend and tie down the stem and branches to encourage lateral growth. This way, more bud sites are exposed to your grow light, resulting in fatter nugs and bigger harvests.
If you’re an expert grower and not afraid to put a knife to your plants, you can see whether topping will work for you. Just ensure that everything else is under control before looking into these more-involved plant training techniques.
14. USE SEA OF GREEN (SOG)
The sea of green, or SOG, method involves growing many small plants in close proximity to max out space and yields. This is especially effective in otherwise small grow-ops, and there is no better candidate than autoflowering strains. Their fast growth and short stature essentially do everything for you. Plus, no pruning or excessive handling is needed.
15. USE PROGRESSIVE HARVESTING
It normally happens that the flowers at the top of the canopy mature faster than those at the bottom. Simply clip off the individual buds that are ready, and wait for the rest to ripen. Wait 1–2 weeks between each harvest and watch for signs that they’re ready to pick. Most autoflowering plants only require two cycles of progressive harvesting, but larger plants may need more.
16. DOCUMENT, REFINE, AND REPEAT
Nobody is born a master cannabis grower. To become an expert, you want to pay attention and carefully record each process used in your grow. Only this way will you notice which techniques render the best yields.
Something can always go wrong when growing cannabis. The key to high yields is swiftly and smartly identifying problems as they occur. As you refine your processes, the health and yields of your plants will improve over time.
