Easy Cannabis Training: How to “Scrog” without a Net!

Published Oct 03, 2020

Growers often ask me for examples of training a cannabis plant for better indoor yields. A plant that’s trained to grow wide and flat in the vegetative stage will produce more buds indoors than a natural-grown plant. Especially with smaller grow lights or a short setup.

One popular way to create a flat  cannabis canopy is a ScrOG which stands for “Screen of Green”. Basically, it means training plants to grow flat along a screen or net.

Many growers use a ScrOG (screen of green) technique to grow flat plants. Plants are trained along a screen or net in the vegetative stage.

This flat plant shape maximizes yields under indoor grow lights by filling the entire grow space with buds, but is there an easier way to achieve the same result?

Although the result is excellent yields, “scrogging” takes a bit of work. In addition to having to make (or buy) the screen and set it up in the grow space, the process of threading plants through the net can be time-consuming. On top of that, once the training process begins, plants can’t be moved independently. With their stems woven through the netting, plants are basically “stuck” on the screen until harvest. This can make it difficult to water plants and/or access the middle.

Today I’ll share an alternative method to achieve similar results. This method of training plants to grow flat gives the same general outcome with less work and allowing you to still move and access the plant as needed. Here goes!

Faux Cannabis “Scrog” Technique

1.) Remove the tops as plant grows

I cut off the top of the main stem (“topped” the plant) after about 5 sets of leaves (5th node). This breaks the apical dominance and causes the plant to grow more wide and bushy. There isn’t a perfect or best time to top a plant, though most growers do it above node 3-6. Topping above the 5th works well every time so that’s what I do.

As the plant grows, make sure to cut off the tops of any stems that start getting taller than the others. This simple system (let’s call it the “top any tall stems” training regimen) ensures no stem gets significantly taller than the others while creating multiple branches. This works well with any plant, including asymmetrical clones like this one, which aren’t great candidates for more structured techniques like manifolding.

Pay attention as the plant grows. If any stem seems to be getting taller than the others, cut off the top.

Other than that, I didn’t do anything but spread the plant out and let it grow wild.

2.) Bend stems until plant is flat

Wait until the plant has grown several branches so you have something to work with.

This Pineapple Chunk clone was topped multiple times and has been growing wild. Ready for training!

The idea of this step is simply to bend all stems over and away from the middle of the plant. The goal is to eventually fill up the tent with a wide flat canopy before initiating the flowering stage.

Time to wrangle it flat!  Stems were bent over and tied down

I got a spool of plant twist tie and cut off pieces to hold all the branches down in place

I used Fiskars scissors to poke holes in the fabric pot and threaded through the twist tie. Another option for securing twist tie is a safety pin, but they can rust over time.

I bent over every branch until the plant was essentially flat and spread out

3 days later the plant has grown into its new shape. It almost fills the tent already!

Quick Setup Summary (in case you’re curious, though this technique works in any setup): HLG 65W (4000k version) LED grow light in a 2’x2’x3′ grow tent (0.6m x 0.6m x 0.9m). Using the Flora trio + CaliMagic as nutrients and supplements.

Time to let the plant grow a bit bigger so it can be spread out more.

3.) Flatten plant every 1-2 weeks until it’s the desired width

8 days later the plant looks like this

I again bent over and secured the tallest branches to be flat

Here is the top view. Notice how much more plant coverage there is in the tent after the plant has been spread out and flattened. The entire tent is going to be a sea of buds at harvest!

Repeat the step of flattening as many times as it takes to fill the grow space.

4.) Initiate flowering with a 12/12 light schedule

Since I’ve achieved the desired coverage, I initiated the flowering stage by putting the grow lights on a 12/12 light schedule immediately after the last picture.

The emerging buds help you see just how many bud sites have been created!

5.) Wait until harvest

At this point, there’s basically nothing to do but water the plant and wait for harvest!
