SCROGING Method Guide - Increasing Your Culture with SCROG
The SCROG is a bit like SOG but less risky compared to the law: basically it is less plants for as much harvest. The SCROGING is done with only a net (or a fence), this old technique of growth aims to improve very significantly the productivity of your crops. The principle is the same as SOG, that is, small plants are grown evenly trying to maximize the number of heads for a given area. Here is a guide for SCROG culture.
By analogy with SOG (screen of green), SCROG is called a culture technique mainly dedicated to indoor cultivation. The SOG method has been popular for years, and the SROG method relies on the same principles, but growers add a screen (net) that can maximize exposure to light. This is how SCROGING is defined.
For this, we have a fence above the plants. When they reach the fence or a little above, they curve to force them to stay under the fence. Then we go into flowering ... We then continue to hold the plant under the matrix, until growth stops and the heads start to grow. We then have a canopy of leaves, and a field of heads ready to explode ...
Optimization of the interior space : The network allows for the deployment of branches with a uniform size, so that almost no space will be present on the upper layer of vegetation. With a net you can achieve the most effective results in terms of optimizing the interior space. And this is the most important parameter of the SCROG method
canopy uniform & level control - One of the most common problems raising cannabis in a closed space is keeping your growing plant uniform. Despite the understandable desire for growers to predict wild growth and fill the large flower part, it is important to remember that it is necessary to maintain a distance from the light source. Especially with regard to an HPS lamp that can burn in a few hours all your hopes of culture.
Maximum exposure to light - The SCROG device naturally exposes all the stems of your germinating plants, the mesh of the net being considered as a multitude of "slot" exposed to the light to accommodate the buds.
Branch support - this positive point is the physical support of the net. This support is essential, especially during the flowering phase when the same massive branches develop in a few weeks.
Long-term growth - The SCROG method has an inherent need of at least 4 at 6 weeks in order to have growing branches deployed correctly over the net. Of course, the parameter of the number of plants is important. Thus, 2 plants will take longer to cover an area of one square meter compared to 4 plants.
The problem of mobility - During the first few weeks of cultivation, you can usually handle the plants and do a proper maintenance. But once branches break through the cracks in the net, it will be difficult for you to reconfigure your growing medium. This obviously does not cancel the necessary maintenance, you will have to use a sprayer to wash your plants or fight against parasites with this one. Show a little ingenuity and inventiveness.
Use cuttings or feminised seeds - Today, most Homegrowers use feminized seeds or cuttings. In the case of the SCROG method, it is an obligation! Unless you are a veteran, you will need to establish a homogenous culture, so the cuttings are strongly solicited.
All basic equipment is necessary for the SCROGING - namely the lamp, ventilation, a growing medium, the controls, etc. But we will add, some essential elements:
Cannabis plants - SCROGING generally involves 2 at 4 plants per square meter. But sometimes you can go up to more 6 or more plants. As long as the good growing conditions are not corrupt, the plants reduce the vegetative transition time and their flowering period.
The grid or net - the net is in fact the only external equipment (almost) necessary for the implementation of this growth technique. In hydroponic gardening stores, nets can be obtained that conform to the design of the canopy. Most of the ingredients can be found in shops specializing in construction, livestock processing, etc.
Nylon net - easy to use and highly manoeuvrable as needed.
Plastic net - not the best choice ... make sure of the quality.
Chicken coop - the cheapest, the most available and widely used. Its main defect, it is inconvenient to work, and rust ... In the end, it can damage the plant.
Fishing net - Although it is a relatively solid material, it is also quite accessible and available. But many producers complain that the stitches are too thin, and what's more, would tend to cut the plant.
String - suitable primarily for assembling small spaces.
Wire mesh - Ready-to-use metal chains can be purchased and arranged as a net. However, it is recommended to ensure that the metal is coated to prevent rust.
Fibers- Another possibility is to form a network of threads with fibers such as cotton, jute, sisal (Agave), and of course, coconut, hemp etc ... We can improvise from almost every materials whose characteristics correspond to the size of the holes, ie 5 to 15 square centimeters.
Fixing - to install the desired height of the net is necessary to establish that the walls of the grasp cavity: You can do it using the feet of the installation, wooden frame or simple nails (depending on the type of net and the convenience of the tower). The recommended height of the network is between 25 and 50 cm (basic plants).
The general steps of the SCROG method
The vast majority of the SCROG network, 75% at 85% is covered with vegetation. To arrive at this situation, it is important that the branches deploy on the network during the growth period. For this, some general steps are needed:
1. network installed at the desired height, above the plants
2. plants grow and reach the network
3. The plugs are distributed through the mesh
4. Now the "magic of SCROG" - take each branch, and expand on your network.
Move them gently to the next hole and in the desired direction.
Illustration of the action:
5. Continue implementation of step 4 to cover a specific area
6. After the flowering phase, compare the result and be careful if some branches do not overflow your growing space
It should be noted
During the deployment of vegetation on the network, identify the main branches and redirect to the outer frame. This is to allow the less developed plants to get better lighting. In addition, this prevents your upper branches from being injured by your lighting device.
In order to maximize the rate of network coverage by your plant and this in order to optimize the production offered by SCROGING, many producers tend to integrate other breeding techniques. They are particularly feasible in the first half of the growth cycle:
Cut - The size of the plant during the first weeks of his life is important. It is usually performed after the bifurcation of the third or fourth branches. Then we will get two new growths, which helps to promote growth across the width.
Pruning - one of the most important actions during the SCROG method. Pruning involves removing all vegetation in the lower third of the plant. This strengthens the development of the upper regions. Pruning takes place during growth, but it will be even more necessary when your plant is in flowering stage, no light will wait for the lower part.
Links - The technique reveals more art, and some control of the SCROGING. It allows to create the desired shape, via ligatures that will be imposed on the branches of the plant
Varieties recommended for SCROG
Another very important parameter for the success of SCROG is a selection of adapted cannabis strains. In general we will take those that respond well to this growth technique. The main characteristics we are looking for are those with laterally expanded growth and which have flexible branches.
The varieties of cannabis that meet these characteristics are usually Sativa strains. But since their long flowering period is a handicap (10 to 12 weeks), hybrids indicated for SCROG culture were preferred. Among these most commonly used varieties will be Satori, AK47, Lemon Haze, and C99. Do not hesitate to consult the community producers using the SCROG method, to find the right strain of the moment.
The "V" SCROG
One of the most interesting ideas for improving SCROG is to establish a curved network. This brings a larger area of exploitation, and therefore a better harvest. Graphic of the idea:
SCROG half vertical
Of course, here you can make sure that your crop matrix grows vertically, the bulb is in the middle:
Of course, here you can take it on a vertical growth in full quantity The bulb is in the middle:
It should be noted that the more sophisticated SCROG methods are not recommended for beginners. It is best to start with the simplest format (flat), repeat until you have mastered it completely. SCROGING is a technique that leads the experimenter to professionalization.
