How To Boost Your Marijuana Garden Yield In Five Easy Steps

How to scrog marijuana plants

You’re either reading this because you’re familiar with ScrOGing or you’re curious about this whimsical term. What is ScrOGing? Actually, the term is ScrOG, which is the shortened form of “Screen of Green”. Still confused? Simply put, to ScrOG is to force the lower growing buds of your marijuana crop to the plants’ canopy by way of light optimization.

A screen is used to force your crop to grow low and dense, forming a canopy of buds at the screen level; thus, the term “Screen of Green”. This practice will yield more usable product for those of you who grow indoors. Sounds good, right? Here’s how to do it:

Step 1: Screen the plants

Secure a screen 20″ to 25″ above your plants. It should be made of sturdy material and have 2″ x 2″ open squares throughout. The idea is to limit the plant’s height while encouraging the formation of buds.

Step 2: Remove colas

When the cannabis reaches about 10″ in height, snip off the colas located at the very top of the plant. This forces the stem to form new branches.

Once the new branches begin to peek through the holes of the screen, carefully manipulate each one into a separate hole away from the main stem. Doing so encourages horizontal growth, making the crop denser. Take some landscape tape and tie the spread-out branches to the screen in order to train them to grow laterally. The result you want to achieve is a dense canopy running along the screen. Watch the video and download my free marijuana grow bible for more tips about growing marijuana.

Step 3: Prune

Before the plants reach the top of the screen, snip off the small lower branches and any side shoots growing at the bottom. This process allows the marijuana plant to concentrate its growth efforts on the top where the buds will form.

Step 4: Force flowering

Force your marijuana plants from the vegetative stage into the flowering stage by putting them on a lighting schedule. Twelve hours of light and twelve hours of darkness will push your crop’s energy into producing flowers or buds. Some growers choose to force flowering just before the plants shoot up through the screen. The flowering stage can take any where from eight to eleven weeks, depending on the strain.

Step 5: Secure branches to screen

As the marijuana plants continue to thrive, train all branches to grow horizontally by attaching them to the screen. Again, use landscape tape to secure them. Be very gentle in this process to avoid damaging the flowering tops. Any breakage that may occur can thwart the growth patterns. Make sure the air is well ventilated below the canopy otherwise you risk the formation of mold in your dense crop.

The process of ScrOGing is ideal for indoor grown cannabis crops, especially if your space is limited. HPS lights are best but fluorescent bulbs will also work. The method is simple to implement and can result in a much larger yield of traditionally grown marijuana.

  1. Educated A Hole on

    That, and make sure the veg time + flowing is the same first. Extended veg isn’t a problem (kind of useful with this method and fewer plants) but it would be a major PITA to harvest some of your plants when the others are sharing the screen.

  2. Educated A Hole on

    Technically it’s fine, but honestly your better off doing them individually or at least with less per screen. Just think about the logistics of it, 8 plants is a lot to work around. Plus, look up LST (low stress training. ScrOG is basically the same.

    And I’d ignore the bit about topping, it’s not really needed when you follow this technique properly. All you’re going to do is stress your plant needlessly.

  3. Hi I have 6 hemlock plants and 2 super silvers , will these be ok 2 scrog them all together.? ….new to all this so any tips would be great.

  4. Educated A hole on

    Nah, I’ve just done a lot of research, Google is your friend! Marijuana has got to be the most commonly researched plant by the average person, and most of those people like to blog.

    Look up both ScrOG and LST (low stress training) if you want to know more about this method+the theory behind it. While the technique varies between these two methods they both do the same thing, but one uses a screen/is a bit easier.

    Personally I like LST more because it’s more involved/you spend more time with the plant. Plus it’s easier to do on the fly (no planning needed to set up a screen securely+buy materials) just grab some string! Though for that exact reason ScrOG is better for most (less contact with your plant=less cross contamination+more free time).

    An article on LST would be a good follow up to this one (plus could explain the theory better)

  5. before u try this make sure you have feminized seeds . if u try this with random seeds not knowing if the plant will be male or female you will be pissed.

  6. Educated A hole on

    You sir don’t seem to understand the purpose of this article. You see, plants have these hormones called “auxins” (which really should have been mentioned in this article. This site has been going downhill man..) which stimulate growth, by manipulating the plant using a screen you are redistributing the auxins causing the plant to produce many sister colas instead of the one main cola. This is like when you see a tree in the forest on its side it has many branches growing up that are around the same size.

    This method is functionally similar to typing or FIM in that you are forcing the plant to put resources elsewhere, changing the way it grows.

    This ALSO allows you to adjust your light less and have better efficiency. Because the plant is now lower and wider the light will be illuminating more if it more closely (and we ask know light reduces by the cube of its distance so every inch counts!)

  7. Educated A hole on

    No you don’t, the whole point of ScrOG is you are doing this to one plant. You are thinking of “SOG” or “sea of green” which is a very different processs.

  8. Those plants are dinky! You can increase your yield by getting a bigger room, more light and letting them grow taller.

  9. The Grim Reefer on

    Scrogings main issue is that in order to do this you have to be ready to go to jail or prison since you must go over limit of plants allowed by law in most states, with the exception of CA, because of prop 420 you can grow more that the standard prop 215 allows. For this reason this is a stupid idea for most people. However for those breaking the law you can increase your yield with this method if you have limited space.
