How To Support Cannabis Plants Outdoors

Every grower wants to harvest big and dense buds, but that can be a problem when growing outdoors. Considering that you don’t have walls or a structure to tie a SCROG net as you would indoors, you’ll have to come up with a way of supporting the extra weight.

1. Why Support Plants Outdoors?

Sometimes when growing indoors, our plants can grow too much in a limited growing space and their buds end up extra heavy, for this reason, growers use techniques to support the branches.

This can also happen outdoors, although then the problem is not the lack of space but heavy buds of your plant.

When growing outdoors growers usually plant in bigger pots, that is because they aren’t limited by space like they would when growing indoors. This allows the plant to grow to its maximum, it will usually take more to flower but the buds will be denser.

A very common problem growers have when growing plants in bigger pots is that the branches can’t support the weight of the extra dense buds. Growing indoors this can be avoided by tying the branches to the sides or top of the growing tent, but outside we don’t have a structure like that.

Cannabis outdoors isn’t limited by space and can grow huge. If you’re growing a high yielder, the branches may not be strong enough to support the buds and snap, this is why you need to provide support, either with bamboo stakes, a trellis net or tomato cages.

Fortunately, there are several ways to support our plants outdoors, this allows us to have bigger yields and harvest extra dense buds.

2. Bamboo Stakes

Bamboo stakes are what growers usually use to support branches. Even though this is a cheap and effective method, be aware that bamboo sticks can rot, that’s why several growers avoid using them.

You can still use bamboo stakes if you’re letting your plants grow for a short time but because they’re exposed to rain and are in the soil, they can rot.

When bamboo rots, it can spread to your plants and they can suffer from mold (like powdery mildew) which can damage your plants and can easily spread to other plants nearby.

3. Trellis Net

Trellising consists of basically Scrogging outdoors, although it can be harder because you lack the structure to do it properly, so you’ll have to build that structure yourself. Even though it sounds hard, preparing the structure for a trellis net is quite simple, and consists only of placing 4 stakes around the plant.

You can use bamboo stakes but if you have a little bit of cash to spend, we recommend using metal stakes, not only they won’t rot but can be reused in your other growing cycles. Depending on the space you have available, you can place the net horizontally or vertically around your plants.

These two methods will support your plant, although when placing it around your plant you won’t be able to control its size like you would with a trellis placed on top of your plant.

When you place the net horizontally (on top of your plants) this will not only support the extra weight but it will also allow you to train your plants like you would in a SCROG.

4. Tomato Wire Cages

Tomato wire cages are pretty similar to placing a trellis around your plant. They will support your plant from every side but won’t allow you to control the height your plant reaches. On the other hand, some growers don’t want to restrict their plant’s height so this is not really a disadvantage.

Wire cages can also be used as a structure to tie the branches to, using string or other materials that won’t damage your plant, you can easily tie the branches to the wire cage, giving the branches extra support.

You can easily find wire cages in hardware stores and they’re fairly cheap, going for around $1.50 each, they can be reused so you won’t have to buy more for your next growing cycle. If you don’t feel like spending money, you can make your own cage, you’ll just need metal wire and you can easily find how to make them on the internet.

5. In Conclusion

Supporting your plants is definitely important when growing outdoors. When growing in bigger pots, your plant will consequently grow more and develop denser buds. If you fail to give support, the extra weight may be too much for your plant and the branches can snap.

Every grower wants to harvest big and dense buds, but that can be a problem when growing outdoors. Considering that you don’t have walls or a structure to

7 Top Tips On Supporting Heavy Buds Indoors

Adding support to your Cannabis plants during the flowering period has many advantages. Not only does it allow the plants to concentrate on producing fat and dense buds, but it also prevents buds from falling over.

In this article, we cover 5 top tips for adding support to your plants when they need it the most.

1. Bamboo Canes

An old school, inexpensive and great way to add extra support for your plants. Sourcing bamboo cane is cheap, easy to sterilize and clean, and will last for a long time if treated well. Canes can be used early on during the growth stage to tie young plants.

Our top tip here is to add bamboo canes that are the same height of the plants, then to insert them on the outer part of the pots. Imagine inserting the canes on the outside like the numbers on a clock, and create a circle that can be used to tie the side branches to the bamboo.

Do not insert the bamboo into the center of the growing medium as this will penetrate the roots and cause stress.


Screen of Green setups is an incredible way to train plants during the vegetative period of 18/6 and then allow them to grow with a solid, hardwood, and thick structure. Most times the net, wire, or trellis that has been used will be made of a lightweight material not really designed to support the weight of the buds.

Our top tip here is to use the SCROG method to grow mature and well-established thick branches. Once the plants are grown, the net or screen could effectively be moved, as it is only used as a guideline for canopy control and manipulating the growth structure and distribution of energy.

3. Tying Up Branches

Tying side branches and main central colas to the adequate support sounds simple enough, however, there are a few things that a beginner grower should consider. Over time the thickness of the branches will expand and may even double in size.

Our top tip here is to avoid using anything such as plastic cable ties or metal wire and choose to use twine or elastic. The reason being plastic and wire ties can cut through the wooden branches as they expand, oftentimes decapitating the branch slowly. Using elastic or twine will give you much more leverage and in an emergency can be cut away easily.

4. The Trellis

It is important not to get confused with a Screen of Green setup and a trellis net. One is designed to be used as a guide during 18/6, in combination with advanced plant training. The other is to be used as a support net later on during the blooming period.

Our top tip here is to use a net trellis that can be easily installed inside of the grow tent, or over a large outdoor plant. The size of the squares in the net will easily fit over your flowering plants and will provide leverage also during heavy winds, and when the weight of the buds causes the plants to topple over.

5. Airflow and Humidity

If the goal is to grow buds so big they need support, then it is essential that the airflow and humidity around the tops and bottoms of the buds are ideal. There is nothing worse than finding out that your dense, frosty buds have become so thick they are molding from the inside out due to Botrytis.

Our top tip here is to keep the humidity as close to 30-35% as possible and to encourage a free-flowing current of fresh air. Make sure that the lower points of the plant are receiving lots of fresh air also, and there is well-balanced airflow around the tops and bottom of the canopy.

In the event that you notice some buds have a gray, candy floss appearance and when touching feel like a spider web, you should cut this part of the plant away immediately to prevent further contamination.

6. Building Tomato Cages

A great extension to bamboo supports and way to box your Cannabis plants in with maximum support, building a frame by tying bamboo canes horizontally to existing bamboo works a treat. There are many benefits associated with customizing the sections to the frame and allowing the side branches to grow out at an angle where they will receive the most light.

Our top tip here is to add the bamboo in horizontal positions that will encourage the side branches to grow outwards. Tying the side branches vertically still works fine, however, the growth structure and appearance will be much improved and the amount of direct light the inner branches receive is increased. This is one way outdoor farmers in California grow such enormous-sized plants.

7. Yo Yo Devices

These small but highly effective devices are designed to be hung directly above your plants, and attached to the designated branches. Over time the amount of leverage is increased to raise the branches to a set height. The benefits associated with using yo yos are that thanks to their small size, it is easy to attach up to 10 of these devices per plant.

Our top tip here is to use these to keep heavy side branches from falling on to other buds. As the plants begin to flower heavily, the canopy will become very crowded, so using yo yos for each individual branch is a wonderful way to prevent buds from touching one another or the sides of the grow tent. Buds will begin to mold and spread if allowed to touch wet walls or begin to lean on other branches.

8. In Conclusion

There are many ways to help support Cannabis plants when they are focusing on blooming that have many advantages. Usually, autoflowering plants grow compact and not always need support depending on the strain.

If you’re growing our Orange Sherbet Auto be sure to prepare bamboo canes to support her super heavy buds and try tying her down to control the hight.

Adding support to your Cannabis plants during the flowering period has many advantages. Not only does it allow the plants to concentrate on producing fat and de
