Apply the Main-lining technique to your cannabis growing

Written by on 23 June, 2020

If you are looking for methods to help you increase your cannabis harvest, the technique named main-lining, might be useful for you. This time we’ll show you the steps to follow.

What is it?

Main-lining is the result of a mixture of LST, topping and ScrOG techniques. Lollipopping, which basically seeks to maximize the spaces (indoors or outdoors) and that your growing produces higher yields by pruning the plants in a certain way.

This method has gained popularity and has been sometimes named “manifolding” or “fluxing”.

How do you apply it?

Generally this technique can be applied to plants born from cuttings, however, it is advisable to do so with those born from seeds, as these offer symmetrical knots.

Once the plant has a size of at least 5 to 6 knots, you should do the first pruning, specifically at the height of the third knot (counting from below). With this, we will obtain an axis by means of a single knot, with which, each one of the first two buds will transmit the energy equally. Then, prune the first two knots.

The first two buds that we achieve in that third knot should be pruned in the same way as you did before (when they have grown a little and have 5 or 6 knots).  With the buds of the two lower knots, use any method of downward attachment, so that they are at the same height, as the single center generated in the first pruning.

In this way, you will have 4 apicals at the same height. Be sure to cut the branches symmetrically for best results, and repeat the operation you have been doing, again (the 4 apicals, when they have at least 5 knots, cut through the third one and prune the 1 and 2; now you will have twice as many apicals, that is 8).

With this objective achieved, you can let your plants continue with their growth.


Get plenty of documentation on this subject and practice this technique with a few plants before doing it with the whole growing. If you perform the main-lining correctly you will be able to grow indoors, with an effect similar to the ScrOG mesh system, but without this element.
