Mainlining cannabis is a great technique that yields interesting results. While it makes cannabis plants look a bit strange, mainlining cannabis definitely has benefits.

What is Mainlining Cannabis?

If you want to know how to mainline, a sophisticated pruning and training technique known as “mainlining” is used to concentrate the development of the cannabis plants on eight to 16 main colas or main lines. Cutting and training for optimal yield in this unique and intense way boost the crop’s quality and the level of control the producer has over it. Mainlining may assist both indoor and outdoor growers with at least moderate expertise. You can start mainlining cannabis plants using SCROG if you want larger, top-shelf buds.

Mainline vs Manifold – What’s the Difference?

To generate several huge, homogeneous colas rather than just one, farmers utilize the training method known as “main-lining.” On the other hand, in manifolding cannabis, we divide the cannabis stem and create a Y-shaped hub. By doing so, nutrients and resources are diverted to different tree parts.

What are the Benefits of Mainlining Cannabis Plants?

Mainlining has a few major benefits that make it one of the best training techniques. Just look at a before and after to see what it can do for your cannabis plant:

Before and after mainlining cannabis

If you’d like to main-line cannabis plant, here are the benefits to expect:

Increased canopy size

One of the best things about a mainline plant is that you keep it growing in the best way possible. You can keep it growing perfectly until its canopy size is considerably large, with the mainlining average yield being significant. The Sea of Green method is one way to ensure lush canopies so that maximum light can be trapped for use during photosynthesis.

Easy to do

As a result of simple canopy control, colas develop to the same height organically. It’s one of the top advantages of the main-lining cannabis plant.

Adaptable indoors and outdoors

Indoors, you get more out of your grow lights. You can use the same grow lights and configuration to produce more crops. On the other hand, if you’re growing outside, you’ll have more control over the size of your plant and less danger of mold growth, which will help you create a more appealing and consistent end product.

Good for limited space

Mainlining cannabis decreases the undesired “stretch” of only a few colas when main-lined cannabis plants initially move to the blooming stage since energy is supplied uniformly across all colas. This stretch often creates height/space concerns for indoor growers.

Only needs to be done once

Main-lining advantages may be obtained with little further effort once the first training is completed early in the plant’s life.

How to Mainline Cannabis Plants

If you’ve decided that cannabis main-lining is for you, then you’re ready to get started with our step-by-step instructions. Make sure your crops are healthy and vigorous before getting started.

What tools do you need

When it comes to cultivating cannabis, this is one of the simplest steps you’ll take. Pruning shears and plant/cable ties are everything you want!

Creating a manifold

The manifold cannabis is the heart and soul of the main-line cannabis operation. There are several ways to use a cannabis manifold throughout a plant’s vegetative period, so we’ll go over how to make one first.

Mainlining - creating a manifold
  • Step 1

When your seedlings have between five and eight nodes, it’s time to transplant them. When it comes to seedlings, it’s critical not to top them off too early. Otherwise, they may not be able to recover. Afterward, snip the plant to the third node.

  • Step 2

Remove any growths and plants below the 3rd node of the branch. Two huge fan-shaped leaves should sprout from the top of the plant’s stalk (Y-shape).

  • Step 3

It’s time to tether your two primary branches together—gently! It’s simple to snap a young cannabis plant’s new growths since they’re so delicate. Shooting horizontally, parallel to the ground, is the primary goal of this training session.

Plant ties or cable ties may be used to keep shoots straight and narrow by securing the other end to the edge of your container.

Mainlining 

Cannabis plants should begin to regrow within a few hours after being treated appropriately. As a result of the central manifold, nutrients and other vital resources will be distributed between the two shoots at the third node. At least eight colas are recommended if you want to get the most out of your plants. Mainlining is the next step after you’ve learned about manifolds. The following is the main-lining walkthrough:

  • Step 1

You must wait until each branch of your manifold gets four new pairs of leaves before you begin to build your tree. Then, as before, top and bottom each side of the 3rd node as before.

  • Step 2

The development below the third node will not be removed this time. Remove just the second node, leaving the first and third nodes intact.

  • Step 3

Repeat the procedure on the opposite side, and you’ll end up with eight shots (two pairs of leaves on both of the main branches).

  • Step 4

Make careful to modify the ties to keep both core branches tied down and the base of the newly formed shoots parallel to the ground to keep plants under control. It’s important to monitor the growth of your newer stems twice a week to ensure that they reach the same height.

  • Step 5

It’s only a matter of providing your plants with the water, nutrients, and light they need to thrive as you wait for them to mature. Once you’re satisfied with the height, go to blooming by adjusting the light schedule to 12/12 (this will depend on your tent, grow op, etc.).

  • Step 6

You’ve done an excellent job if you’ve followed the instructions for the letter. Eight thick colas will be ready for harvest in the next few weeks once your plants have been properly main-lined. While the plants are in blossom, you may continue to trim and care for them in the same way.

Tricks and Tips for Mainlining Cannabis

  • Trim superfluous fan leaves shortly before blooming or during the first two weeks of the flowering period is critical with a main-line cannabis plant, despite being a general recommendation. As a result, all of your freshly developed colas will get the attention they deserve.
  • Mainlining shouldn’t begin until the plants are healthy. When it comes to topping and training your plants, we can’t emphasize enough how critical it is that you only do it on healthy plants.
  • Check on them twice a week to keep your plants in good form. Astonishingly fast growth and stretching occur during the vegetative stage. You should examine your plants twice weekly and alter the ties based on the symmetry concept of main-lining cuts.
  • Cannabis seeds inherently generate symmetrical nodes, making the creation of an invariant manifold much simpler than it is with cuts. When consuming cuts in large doses, you’ll have to rely on your judgment.
  • It would help if you struck a balance between keeping the symmetry of the mainlining and allowing branches to grow spontaneously. Don’t tie down branches too tightly. Using cable ties may cause harm to tender young branches and shoots.
  • When using a hydroponic arrangement, it is possible to main-line your cannabis plants. Because the plant won’t be anchored exactly in the earth, you’ll want to use caution while tying it down, but it works just as well!

Mainlining vs LST

It’s not a choice between LST and main-lining; it’s a matter of adopting both. You should stick to main-line cuts if you have limited room in your grow tent. If you’ve got some spare space, give LST a try and see what happens. LST is popular among novice or inexperienced growers since it doesn’t need aggressive topping.

Mainlining vs Supercropping

Super cropping is a labor-intensive method of shaping the main-lined plants. It’s a favorite of many gardeners. Compared to super cropping, main-lining cannabis is quick and easy to set up after the manifolds are in place. The grower’s involvement is minimal at this point.

Try Mainlining 

Improved yields may be achieved using a simple, low-cost, and labor-inefficient method known as “main-lining.” It’s hard to think of a reason not to grow cannabis regularly when the benefits outweigh the drawbacks.

However, there are a few exceptions to this rule. For example, autoflowers should not be used as a mainline. As a result, any stress caused by topping will only affect the final yields of main-lining autoflowers. Mainlining, in general, is best suited to medium or tall-sized strains since you won’t be able to observe the advantages if you’re growing dwarfs.

There are few better ways to get your cannabis plants to grow to their full potential than by main-lining. At least eight overflowing sodas never grow boring to look at.
