how to grow short bushy weed plants

Whichever technique you choose, you’ll see an increase in yields. If you aren’t sure which method works best for you, try both and see which you prefer.

To prune cannabis plants:

Topping is done during the vegetative stage to help redistribute growth hormones from the main stalk to side branches—by cutting off the main stalk, the plant will redirect its energies to side branches, forcing them to grow out, instead of up. Topping makes a weed plant bushier.

With one vertical stalk, the main cola will get a lot of light, but the lower branches will get shaded out by the main cola, producing larfy buds down below. With a bushy shape, you’ll get more buds, and they’ll be of a higher quality.

As mentioned above, pruning removes cannabis leaves and branches that are dead or won’t receive much light. Again, it might feel strange to intentionally cut off bits of your plant, but without the proper amount of light, buds will be a poor quality.

Although it may seem strange to cut off and throw away part of your cannabis plants, topping is essential to keep your weed plants healthy and to get quality yields.

The rule of thumb for plant size is the bigger the pot then the bigger the plant. As long as you have a vibrant healthy root system, then growing in huge pots can lead to huge plants and vice versa. A good tip here is to grow in plant pots that are wider than taller. The reason being that when roots fill out wider pots, as an anchor effect, the plant from the soil up, will grow bushy and wide. These plants are then even easier to train to stay small.

A very important factor when considering how big you want your plants is of course genetics. So choose wisely if space is an issue. Cannabis is made up of Indica and Sativa and understanding the difference between these two is a great advantage. For small to medium sized varieties, Indica strains are recommended as when these varieties are flowered, there is a short space between internodal growth and especially during blooming.

Also known as the growing phase (18 hours light/6 hours dark), the length of time you veg a plant for will determine its overall size and yield. A great tip is to only veg the plant for a shorter time. If you are growing in a Sea Of Green scenario, then the plants will stay around 60cm on the basis that during flowering the lighting is not too distant and should remain closer to the canopy.


This is really the most hands on way the grower can ensure a low profile canopy. The first form of plant training is ‘Low Stress Training‘ (L.S.T) which involves taking the main dominant shoot that has an auxin to grow vertically, then tying down this shoot so it is no longer the highest point in the canopy. By doing this only once, the rest of the shoots around the plant will begin to grow more laterally and many more potential bud sites grow. Once this stage is done then you can pinch out the top shoots of the new growth. The principal behind this is to create two new shoots where once there was one. Choose how many shoots you want to finish with and now is a great time to incorporate a net to feed the new growth through. By doing this method known as ‘ Scrog ‘ you can ensure that everything through the top of the screen has light to grow up to, and that anything under the net will be cleared away.

There are many variables involved when attempting to keep a Cannabis plant small and squat. Below are a list of the potential factors that can reduce unwanted plant height and allow the plant to better focus its energy.

The internodes of the plant determine what difference in size there is, between each new primary shoot. A great way to keep internodal space to a minimum is to keep the lights close so the plants do not need to stretch and reach for the light. Many growers have excellent results during veg by using CFL lighting. This soft form of fluorescent lighting is what plants require during the growing period. LED is also great for short internodes.

Use the right grow light – CFLs, T5s, and certain LEDs are great choices for small grow spaces. I’ll break down the pros and cons of each and share the specific models that have kept plants short for me. LEDs are probably your best choice (they stay cooler and small ones can be kept very close to plants) but I’ll quickly go over all the grow lights that can be used for short spaces.

The grower wants to keep plants as short as possible

1.) Genetics

“Top” your plants when they’re 3-4 weeks old

You can produce impressive buds on a small plant with a powerful grow light and high-yielding genetics

2.) Grow Setup

Training techniques such as LST (low stress training) and supercropping (extreme bending) are especially handy if you need to change your overall plant form or reduce the height.
