Scrogging In 5 Steps – Increase Your Marijuana Yield

I love marijuana how to scrog

Marijuana scrog 5 steps

Many of you marijuana growers have probably heard the term “ScrOG” before. Much like many growing techniques, scrogging marijuana strives to make the process a little bit easier and a lot more beneficial. The term “ScrOG” is an abbreviation of “Screen of Green.” The idea behind the scrog method is to optimize your lights and to bring lower buds up to the top of the canopy where they could produce higher yields. It’s a method that has been around for a while (prior to high-intensity discharge—HID—lamps) and has been used effectively, even with basic fluorescent lights. Here’s how to do it;

 

1. Place a screen at 20 to 25 inches from the pots
2. Cut off the top cola of each plant
3. Prune bottom branches when top hits the screen
4. Force into flowering 2 days after pruning bottom
5. Attach all branches horizontally to the screen

Perhaps the most important thing to have with a scrog setup is a screen (generally some kind of wire or even a tight rope). A sturdy screen that can hold back the top canopy and has 2-inch by 2-inch squares built in will certainly be adequate. Screens are also the most important aspects of scrogging. You are effectively “training” the marijuana plants to grow in your desired direction without having to do anything harsh that could affect growth adversely. The distance between pots and the screen should be 20 to 25 inches

This is particularly useful for individuals who either have limited vertical space or limited light emission. Having a screen over the top of the plants, keeps them lower, but it also allows the light to concentrate more evenly on each of the plants. In addition, horizontal growth will still produce useful plants in the long run. Download my free marijuana grow bible at this link and learn to grow like a pro!

 

A Method to the Madness

But, the scrogging method isn’t all about setting up a screen and watching your marijuana grow. Although very little work is involved in general, you will still need to take great care if you want to scrog correctly.

One of the first things you’ll want to do is cut the top colas off of each plant when the plant is around 10 inches tall. This encouraged the plant to create new branches that you can manipulate in any way you please. The ideal way to manipulate the new branches is to wait until they have reached the screen. At this point, the tops of the branches will be slightly poking through one of the holes in the screen. You’ll want to continue to take each branch from each plant and move them over to the next hole so that horizontal growth can continue relatively unimpeded. Or bend and attach all the branches to the screen with some wire horizontally.

Obviously, if you let the plants continue to grow vertically, you’ll run out of space. However, if the marijuana plants are “trained” to grow horizontally, you will ultimately get more yield and a better canopy later on.

Just before the top of the plant hits the screen, cut off all the small branches and side shoots at the bottom. This give a boost to the top colas because there will be no energy wasted on the growth of useless and small side shoots and fluffy buds.

The process of taking the branches out of one hole in the screen and placing them in a hole farther away from the plant base is often referred to as “tucking.” This should be carried out with the utmost care as any breakages can cause your marijuana plants to reduce growth. Some marijuana growers like to make their screens adjustable so that they can raise the “ceiling” if the growth becomes too abundant. This is really beneficial if you want to keep your plants in vegetative state for as long as you can.

Another way to ensure that the plants produce higher yields is by maintaining a relatively even canopy all the way across. This will involve cutting off the top portion of a plant to shorten it and also make room for deviations in the branches. The more branches you have, the more you can continue tucking. Since the growth is diversified and the light is hitting every viable part of the plants, the yield will increase when harvest time comes around.

When to Flower

Because scrogging represents an indoor growth technique, the shift between vegetative state and flowering state will be up to the individual grower. The timing should be ideal, but there are many different factors in play. For instance, if you’re using a hydroponic system, you might be able to take the plants from vegetative growth into flowering within a matter of only 3 to 4 weeks. If the plants are in soil, it should take around 6 to 8 weeks.

Forcing flowering is something that almost takes an intuition. You can see when the plants have sort of maxed out in their vegetative state. You will obviously want to visualize how much the plants will continue to grow once they enter flowering. When you decide to go for it, put the plants on a 12/12 light regimen. Then, growth will start to increase as the plants begin to flower extensively. Carefully train all branches and shoots through their individual slots in the screen. I always force my marijuana plants into flower just before they start to grow through the screen.

From there, the yield will start to take shape, and you’ll be rewarded with almost double the buds of a normal crop. Be sure to take extra caution while training the plants during flowering. They will naturally start to stretch through the holes in the screen and it’s important to not be too rough with them. Keeping the area below the canopy well-ventilated will also help reduce the risk of mold.

 

 

After that, you can start harvesting and enjoying your increased “ScrOG” crop. Have you ever grown marijuana in scrog before? And what are your experiences? Please let me know. And don’t forget to like or share :)

  1. Hello, i am learning so much with all this information, but at the same time i am very sad because i realize that my plants are growing very slow :( you said that i might be able to take the plants from vegetative growth into flowering within a matter of only 6 to 8 weeks in soil, but i have like 5 weeks with mines and they are 11 cm and only 5 sets of leaves. I have them indoors, with soil, fluorescent bulbs.
    Dont know what i am doing wrong, maybe the seeds were too old?

    • I have seen videos of scroggs where they use the vegetable trellis netting, this is what I thought I would try. My only issue is the spacing you mention in between pots. I have all of my pots centered under my main light ( a 90 watt led grow lamp) and three 200 watt cfls on the sides of the pots to cover the lighting they might not pick up from the led lamp. Will a scrogg screen help me increase yeild even though my space between pots has to be so limited?

  2. Laura, it could be anything. However, I’d say based on your description, you may have a lighting issue. Get better lighting. And check your nutes.

  3. how many plants can i grow with scrog in a 4x4x6 tent? I have 1000 w MH/HPS and good ventilation/smell control but heat topped out at 85f. 8 oz first time, didn’t veg long enough under cfl lights

    • Hi John,

      I would recommend between 10 and 20 plants. With 10 plants you have to veg a little longer but the investment in marijuana seeds, soil and containers is lower. If you grow on soil use 6 gallon pots if you go for 10 plants and 3 gallon pots with 20 plants. Choose a dominant sativa marijuana strain like amnesia or super silver haze because they tend to grow tall. Rule of thumb; switch to 12/12 when plants are touching each other

  4. Amazing information! I’ve learned a lot and look forward to applying this knowledge. One question I have is about the stage where the plant starts growing through the screen, and your clipping it down with a tie to make it grow horizontal. You say the “the branch keeps growing, repeat the previous steps.” Do you mean- continue to tie down the branch multiple times across different “squares” when it grows up/vertical every couple inches?

    Lastly, if you don’t mind, could you please give a brief description of what a good “horizontal field” looks like?

    Thanks so much! I really appreciate it! Once again, your information is invaluable!

  5. Hello i am wanting to grow outside but woried about people passing and smelling it what seeds are the least smelling when in flower ? thanks
