How do you Create a Screen of Green SCROG?

The screen of Green (SCROG)

Description

The basic idea of the Screen of Green (SCROG) method is to control the growth of hemp plants with the aid of a net or lattice. The goals are:

  1. To ensure that the hemp plant does not grow too high
  2. Make sure that it grows in a controlled manner to ensure a good use of the acreage.
  3. The uniform growth in width and height ensures that the plants are illuminated evenly and can form many buds.

How exactly you have to proceed with this cultivation method, we will explain to you in the following steps exactly.

Application of the Screen of Green Method in practice

Step 1: The optimal structure

There are two main things to consider when building the Screen of Green Method.

The positioning of the plants:

Since we are working with this method on fairly broad and stocky plant growth, the pots should not be too close together (very different from the Sea of Green method). We recommend a distance of at least 30cm to the next pot so that the hemp plants can fan out wide.

Attachment of the grid or net:

A net is placed between the hemp plants and the lighting. Up to this height, the plants will grow later before they actively intervene in their growth.

Step 2: Cutting & Tying the weed plant

In the growth phase, the hemp plants are cut off the tip of the main shoot causing them to stop their height growth and more in width. The ramifications that form sideways are fixed on the net so that the area is maximally utilized. The effect looks like the Sea of Green method, a flat surface with green hemp plants. In order for the hemp plants to concentrate their energy on the higher branches (the buds will form later), deeper ramifications can be separated.

Depending on the hemp variety, the vegetative phase may take a week or more, depending on how fast this variety grows. Sativa varieties, which are characterized by a greater height growth are thus significantly shorter in the vegetative phase than Indicas.

Basically, in this phase, the plant through the forming shoots, always in width to draw and fix the ramifications on the net. As a result, several flowers can form during the flowering phase instead of just one. It creates, so to speak, a sea of flowers.

Step 3: Initiate flowering

If the optimum density is achieved through the broad growth, ie the area is fully utilized, then the flowering phase can be initiated. The exposure time is thus reduced from 18 hours to 12 hours.

Now you allow the plant to grow up through the grille. Try to keep as many leaves as possible under the lattice to give the buds the maximum amount of light. Some of the leaves that have formed between the buds should, however, be preserved that they are the source of energy of the plants.

Considerations:

Half cut each finder of each leaf. So the plant still has the possibility to absorb light, but casts less shadow and focuses more on the flowering.

Step 4: Final flowering phase

If a carpet of flowers has formed after a few weeks, excess branches and buds that do not receive light should be removed. This procedure has two positive effects.

  • Removal provides better air circulation, making hemp plants less susceptible to mold.
  • The plant uses its energy on the main buds

Important instructions:

  1. Since the Screen of Green (SCROG) method has a very dense foliage roof and thus a very high temperature and humidity between the plants, good aeration is of great importance. If you do not have them you can quickly become mold and attack the whole culture!
  2. It should be ensured that only female weed plants are cultivated. Subsequent removal of some plants from the grid is very annoying. In the best case, you will work with female clones like the Sea of Green method.
