Benefits of Growing Cannabis Outdoors

Growing cannabis outdoors offers numerous benefits that make it an attractive option for many cultivators. One of the most significant advantages is the reduction in costs. By harnessing the power of natural sunlight, outdoor growers can cut down on energy consumption and avoid the expense of artificial lighting and climate control systems. This not only saves money but also makes the growing process more environmentally friendly.

Outdoor cannabis plants can grow larger and produce more buds compared to their indoor counterparts. The ample space and natural conditions allow the plants to thrive, resulting in higher yields. Additionally, outdoor growing promotes a more natural and organic approach. Without the need for synthetic fertilizers and pesticides, growers can rely on organic methods to nourish their plants and protect them from pests.

Overall, growing cannabis outdoors allows for a more sustainable and cost-effective cultivation process, leading to healthier plants and more abundant harvests.

Understanding the Life Cycle of Cannabis Plants

Understanding the life cycle of cannabis plants is crucial for successful outdoor growing. Cannabis plants go through several distinct stages, each with its own requirements and characteristics:

Germination (1-3 weeks): This initial stage begins when the seed absorbs water and sprouts. The seedling emerges, and the plant starts to develop its first roots and leaves.

Seedling (1-2 weeks): During this stage, the seedling grows its first set of true leaves and begins to photosynthesize. It’s a delicate phase where the young plant needs protection from extreme weather and pests, and mastering the seedling stage is important to ensure strong, healthy plants further down the road.

Vegetative Growth (4-6 weeks): In this phase, the plant focuses on growing its stem and leaves, developing a strong root system. This is when the plant gains most of its height and foliage, preparing for the next stage, and understanding the root zone is vital.

Flowering Stage (8-12 weeks): The plant starts to produce buds and flowers. This is a critical period where the plant’s energy is directed towards bud development. Proper care and nutrition are essential to maximize yield and potency.

Harvest (1-2 weeks): The final stage involves harvesting the ripe buds. Timing is crucial to ensure the buds are at their peak potency and flavor, and is an important facet of how to harvest weed. Proper drying and curing techniques are also important to preserve the quality of the harvest.

By understanding these stages, growers can provide the appropriate care and environment for their cannabis plants, ensuring a successful outdoor grow.

Germination 

Everything starts with the seed. For beginners, starting with feminized seeds is crucial as they guarantee female plants that produce buds, thereby maximizing yield and simplifying the growing process. Whether you’re working with feminized, autoflowers, or regular photoperiod strains, you need to give your plants a strong start.

get a cannabis seedling tray

Invest in a simple seed germination setup: a humidity dome, seedling tray, and some quality propagation plugs or jiffy pellets. These small items can make a huge difference in success rates as they help regulate moisture and warmth during germination. Inconsistent humidity can cause weak sprouts or stunted growth. With a proper germination tray, you give your future plants the best chance to grow into healthy beasts.

Best Outdoor Grow Setup: Which Pots?

Once your seedlings are ready to move out, you’ll need quality pots to support growth. While some growers plant straight into the ground, using fabric pots or smart pots can be a game-changer for root health and overall plant vitality. Fabric pots allow better airflow to roots and prevent overwatering by letting excess moisture drain naturally. They also help avoid root circling, which is common in traditional plastic pots.

smart pots for outdoor growing

If you’re growing big photoperiod plants, consider going even larger – 50L or more. And remember, bigger pots = bigger plants, as long as you feed and water them right. Adequate root space is crucial for plant growth, as restricted root space can limit the size and health of your cannabis plants. You can research planting in the ground vs containers to decide which method works best for you.

Best Outdoor Grow Setup: Soil and Nutrients 

Arguably the most important part of the best outdoor grow setup is what your plants are growing in. A high-quality organic soil blend gives your plants the nutrients they need without constant feeding. Many growers opt for a super soil mix, which you can make yourself or buy pre-mixed. Mixing peat moss with compost or other organic matter can improve soil structure and nutrient retention, especially beneficial for sandy soils.

use worm castings for better soil

Supplements like worm castings, kelp meal, and fish hydrolysate build a living soil system. Over time, this can reduce your reliance on bottled nutrients while improving plant health and terpene production. Using soil amendments is crucial to enhance soil health and nutrient availability throughout the plant's lifecycle. If you do go the bottled route, look for locally made organic nutes – they’re often more affordable and designed for SA conditions.

Efficient and Smart Irrigation

Proper irrigation is essential for the healthy growth of outdoor cannabis plants. Consistent moisture is particularly important during the vegetative growth stage, but overwatering can be just as harmful as underwatering. To achieve the right balance, consider the following efficient and smart irrigation techniques:

Drip Irrigation: This method delivers water directly to the roots, minimizing evaporation and runoff. It ensures that the plants receive a steady supply of moisture without waterlogging the soil.

Mulching: Applying mulch around the base of the plants helps retain moisture in the soil. Mulch acts as a barrier, reducing water evaporation and keeping the soil cool. It also helps suppress weeds and improve soil health.

Soil Testing: Regular soil testing can help determine the optimal watering schedule for your plants. By understanding the soil’s moisture levels and nutrient content, you can adjust your irrigation practices to meet the plants’ needs.

Implementing these techniques will help maintain consistent moisture levels, promoting healthy root growth and overall plant vitality.

If you’re looking to put together the best outdoor grow setup, make sure you don’t overlook your watering practices, as you can really optimize your garden with irrigation. Managing excessive heat is also crucial, as containers can heat up quickly in sunlight, potentially harming root growth and overall plant health.

drip irrigation for better watering

A drip irrigation system with a timer helps deliver water directly to the root zone without wasting a drop. This is especially useful to outdoor cultivators growing weed in the hotter provinces. Mulching can also help retain moisture and protect roots from excessive heat.

If you’re hand-watering, be sure to use a watering wand with adjustable pressure to avoid damaging your soil or splashing dirt onto your leaves.

Pest Control for Outdoor Grow Setups 

Even the healthiest plants attract pests. From aphids and spider mites to caterpillars and whiteflies, the best outdoor grow setup has to contain protection. Knowing how to keep bugs and pests away from your cannabis is vital to healthy plant development. Using natural pest control options is best for home growers. Neem oil is a staple for many cultivators, along with insecticidal soaps and beneficial insects like ladybugs.

pheromone traps will help reduce pest activity

You can also consider setting up some pheromone traps around your garden to pull would-be plant ruiners away from your dagga and lead them instead to their doom. Netting and companion planting can also go a long way, and should be a part of any outdoor grow setup. Marigolds, basil, and garlic are great deterrents and come with the added advantage of enhancing the ecosystem around your cannabis garden. Using organic fertilizers can help improve soil health and naturally deter pests. Additionally, sprinkling diatomaceous earth around the base of plants can ensure hungry pests meet a gnarly demise before they can feast on your crops.

Weather Protection: Shade, Wind, Direct Sunlight, And Precipitation Defense

South Africa’s weather can be unpredictable – high winds in the Cape, hailstorms in the Highveld, and scorching summer sun across the Interior. Knowing how to protect outdoor cannabis from extreme weather is key to a successful outdoor grow. Understanding local weather patterns is crucial as they can significantly impact plant health and yields.

A simple structure made from PVC piping and shade netting can provide windbreaks and a degree of sun filtration for younger plants or during heatwaves.

If you’re an experienced grower and you’ve ever had a hailstorm destroy your crop overnight, you’ll know the values of covering your plants without blocking sunlight.

Support Structures 

If you’re growing cannabis the right way, you’ll certainly need these because when your plants start flowering, the weight of those big, big chunky buds can become too much for stems to support – especially in windy areas. When selecting support structures, it's crucial to consider the size and growth potential of the final plant, as outdoor cannabis plants can reach significant heights. Using bamboo stakes or a trellis system helps prevent branches from snapping and keeps your canopy even.

Some growers even repurpose old fencing or wire for support – just make sure it’s clean and rust-free.

The Final Touches: Tools and Monitoring 

To round off the best outdoor grow setup, you’ll want to have a few basic but essential tools on hand:

- PH Meter and TDS Meter

- Pruning Shears/Scissors - for essential maintenance and training

- Digital Thermometer and Hygrometer – because temperature and humidity levels matter. Understanding the growth cycle is crucial for effective monitoring and ensuring your plants thrive.

Visiting a local garden store can provide you with essential tools and expert advice, helping you select the right soil and nutrients for your cannabis plants.

Should You Invest in Plant Training Equipment?

If you’re aiming for higher yields (and of course you are), better airflow, and more light penetration, plant training isn’t just an optional extra – it’s essential. Using containers for growing plants can also offer better control over soil quality and moisture levels, enhancing overall plant health. If we’re looking to grow our best cannabis, our best outdoor grow setup has to include the tools necessary for techniques like low-stress training and Screen of Green. The techniques can dramatically improve the structure and productivity of your cannabis plants, especially in an outdoor grow where they’ve got loads of space to spread out.

LST Clips and Benders

LST clips gently bend stems outward to open up the plant’s structure. This allows more light to reach the lower nodes and encourages side branches to grow upward, increasing bud sites without stressing the plant. They’re easy to use, reusable, and perfect for growers who want to avoid topping or high-stress techniques.

Scrog Netting

Scrog netting, on the other hand, is used to train multiple branches horizontally along a grid. As the plants grow through the mesh, you guide each top along the net, creating a flat, even canopy. This not only improves light distribution but also helps control height and encourages uniform bud development.

These tools are especially useful for outdoor growers in urban areas with limited vertical space or who want to keep their plants discreet. A low, bushy plant trained out wide is easier to conceal and often yields more than a tall, skinny one. Understanding local climate conditions is crucial for successful plant training, as it helps you adapt your techniques to the specific needs of your environment.

Integrating plant training gear into your toolkit is one of the smartest upgrades you can make when refining the best outdoor grow setup. It’s affordable, effective, and gives you hands-on control over how your plant develops – turning good genetics into great results.

Should you Grow Cannabis Outdoors in Raised Beds?

If you've got the space and want to level up your grow area, raised beds are an excellent upgrade. While pots are great for mobility and control, raised beds offer a more natural, soil-based growing experience - with the benefit of increased root space, better drainage, and stronger overall plant health.
