Every grower wants to know how to grow cannabis outdoors and harvest big 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. Obviously, you're not obligated to do it but why risk those beautiful buds at the end of the flowering period?

1. Why Support Plants Outdoors?

Sometimes, when growing indoors, our cannabis 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 the heavy buds of your cannabis plant.

 

Support cannabis plants outdoors: why support plants

Cannabis plants can grow very big and with the support they can produce extra heavy buds.
 

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 cannabis plants in bigger pots is that the branches can’t support the weight of the extra dense buds. When 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, with either bamboo stakes, a trellis net, or tomato cages.

Pros and Cons By Method

Wire cagesEasier to move each pot individuallyCan be expensive

 

Fortunately, there are several ways of heavy buds outdoors, this allows us to have bigger yields and harvest extra dense buds. Now, all of the methods you’ll read will definitely support your extra heavy buds but, before reading about the recommended methods, let’s take a look at their pros and cons.

2. Bamboo Stakes 

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

Bamboo stakes can help support your plants, although watch out because they can rot.
 

You can still use bamboo stakes if you’re letting your cannabis 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 cannabis 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 (aka Trellising)

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 (or trellising) 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.

Trellis nets can be placed on top of the plants or around them, depending on the space you have available.
 

These two methods can be used to support your cannabis plant when you grow weed outdoors, 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 cannabis plants like you would in a SCROG.

“Avoid using a thin net because it can end up cutting into the branches!”

4. Tomato Wire Cages

Tomato wire cages are pretty similar to placing a trellis around your cannabis 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.

Using tomato cages is a good way to support cannabis plants, they are fairly cheap and can even be made at home.
 

Wire cages can also be used as a structure to tie the branches to, using string or other materials that won’t damage your cannabis 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

If you're wondering how to grow outdoor weed and the basics, have in mind that supporting your plants is definitely important when growing outdoors. When growing cannabis 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. It really doesn't matter what you use to support your plants, you can use either:

  • Bamboo stakes;
  • Trellis net;
  • Plant yo-yos;
  • Tomato cage.

When you grow cannabis outdoors you cannot control the light cycle so usually, plants vegetate for a long period and then flower for even longer, this is why you should definitely provide support to all the branches to avoid snapping. When a branch breaks, it is definitely possible to fix it but it’s also easier for bugs and mold to attack your plant because there’s an open wound and, due to being weaker, it will be harder for your plant to fight against the attack. 

So make sure you have everything planned out before starting your grow cycle, meaning that you should know approximately for how long your plant will grow, how tall, and, if possible, the size of the buds. Keep in mind that supporting the branches isn’t always needed; If you’re not planning on growing a huge plant then it most likely isn’t needed but, depending on when you start the cycle, your plant may reach up to 300 cm in height and this is when you definitely need a way to support the branches. It doesn’t matter how you do it, as long as you do it at the right time and correctly, you avoid any kind of problems.
