The term “SCROG” in scrogging actually comes from “Screen of Green.” Scrogging is a type of training for marijuana plants that involves securing a screen above the canopy of your plants, and then tying the growth from the plants onto the screen as time goes on. Proper scrogging works best if you also use other methods, such as topping. Topping basically involves cutting off the tops of your marijuana plants, so they grow outwards rather than upwards. This helps them grow more branches and become bushier, and scrogging helps every part of those branches and leaves to get exposed to sunlight, making for an extremely efficient use of space.
The Sea of Green (SOG) has been popular for years, and the SCROG method relies on the same features, but growers add a screen that can maximize light exposure. Screens can be as simple as chicken wire or nylon netting that allows you to hold back the tops of the growing canopy. Ideally, the screen should have holes with a 5-cm diameter.
Benefits of SCROG
If you leave a single plant in a pot to grow without training, chances are it will develop just one central cola. With SCROG, every branch develops into a decent sized cola. SCROG growing produces homogenous buds. All of the cannabis branches are trained to hover atop the screen in a canopy. This means that they are all equal distance from your light, giving every flower the opportunity to soak up as much solar juice as they need. Using SCROG, you’ll get a consistent crop every time. This method is particularly useful when growing sativas. Sativas tend to stretch tall during the pre-flowering phase. They can also be difficult to grow indoors since they tend to be tall plants. Though, indicas perform equally well in this method.
Using a screen also simplifies maintenance. There’s no need to tie down branches in random, wonky ways. Rather, the screen provides a simple grid for you to use. You can also use both cuttings and feminized cannabis seeds in this technique.
Scrogging is perfect for people who live in a state where growing marijuana is legal, but only in small amounts. If you are trying to get as much weed out of your garden as possible, this isn’t very many.
How to use SCROG Method?
Cut a screen to fit the area of your grow room (or tent) and hang it, so it’s about 15 inches above your marijuana plants. Only do this if you have between 20 and 25 more inches of space above that, since that is where the lamp will need to hang when your plants are as tall as the screen. Use cable ties to attach the screen to allow for some movement. Screens should be kept as close to your lights as possible, and you can train your plants’ tops to increase the number of marijuana buds that have access to light. You can grow all of our marijuana strains with the SCROG method, and it works just as good with Indicas as it does with Sativas. Because Cannabis Sativa has a tendency to stretch during the first few weeks of flowering, the plants are an ideal option, and you can use the screen to keep the total height of your indoor marijuana garden down, making sure that your buds do not burn under intense indoor lights.
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. The main concept behind the SCROG method is that instead of growing a single top bud, you can grow multiple colas under your light. As your plants grow through the screen, you simply pull them back down and tie the branches to the screen. This creates more budding sites and allows you to maximize your indoor marijuana harvest. Plants can easily be tied down with plastic ties, and you can guide the branches to the empty sections of your screen. As the plants grow, they will branch out, and you’ll get a crop of massive buds that have access to the light on which they thrive. Keep in mind that you’ll probably see more branches when you turn your lights back to 12 hours of darkness and start the flowering period.
Because the SCROG method attempts to create more budding sites, removing the larger fan leaves allows your buds to get more energy, so you can harvest dense buds that are coated with trichomes. It’s essential to keep in mind that the plants depend on sun leaves for energy, and you may want to be sure that you don’t remove too many of the larger leaves. In a method like this, your plant can thrive without extra leaves thanks to the canopy structure.
If possible, use an air-cooled light. Make sure you have at least two fans going: one to pull fresh air into your grow room/tent, and one pulling hot air out of your space.
One of the nice things about SCROG is that it can save time while watering. Make sure you only water when your soil is completely dry. Overwatering is one of the most common rookie growing mistakes, and it will only increase your chances of a mold, pest, or pathogen outbreak.
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.
Your plants become the bushiest during the vegetative phase, so even though the flowering phase is the most rewarding, the vegetative phase is also extremely important. During the vegetative phase, make sure to bend any parts that are poking their way upwards back down, so they remain on the same plane as the other parts of the plants. This will allow all the plants to grow upwards in even rows, maximizing the energy from the grow lights.
