When to Move Your Plant Outdoors

Although you shouldn’t be paranoid about the climate of the area you live in, cannabis is still susceptible to extreme weather patterns. Prolonged periods of temperatures above 88°F (32ºC) will stop the plant from growing, while temperatures below 55°F (12ºC) can even cause death.

It’s typical to transfer your plant outdoors when it’s in a 1-3 gallon container. This provides the plant with exposure to nature’s elements at an early stage of life – it ensures the plant is hardy and strong. Plants that remain indoors for an extended period are typically far more likely to have poor or stunted growth. It’s critical to remember that the goal of growing marijuana outdoors is to maximize yield, the greater exposure a plant has to outdoor sunlight the bigger the yield!

In North America seedlings should be started in early spring when growing outdoors. Plants develop the most when the days are longer and more sunlight is available – this ensures your plants achieve their maximum potential genetic yield. Then, by the time autumn arrives, they’ll be ready to flower and complete their life cycle.

The surefire way to know when to water your plants is to get your hands dirty. Dig a finger about an inch below the soil’s surface – if it feels damp, it means that the plants have enough water.

A typical outdoor marijuana grow requires watering every 2 to 3 days. This is also very dependent on local climate (dry vs humid) and the soil type. Water requirements increase in late summer when the weather is hotter and more evaporation occurs. This is a time when the plant is transitioning to the flowering stage.

If you’re planting in pots ensure there’s plenty of drainage holes at the bottom of each container. Marijuana plants with too much water can experience root rot, foliage damage, and invite unwanted pests and mould.

Pruning Techniques

Pruning achieves one primary purpose: to maximize yield. A basic pruning technique that is straightforward and uncomplicated is to trim leaves that are beginning to wither. They’re taking precious energy from the plant that can better be used towards growing the resin-filled marijuana flowers. Follow these steps for a successful trim of your outdoor crop:

  1. Focus on lower leaves that are withering, a very easy win for the plant.
  2. Move on to leaves higher up the plant that are receiving limited light and are not thriving.
  3. Remove undersized buds lower on the plant, as it should allow the plant to refocus energy on growing larger more resinous buds higher on the plant.

It’s critical not to over trim, this can shock the plant and ultimately result in plant stress or stunted growth – exactly the opposite effect you’re intending! If you’re unsure about your green thumb, just stick to step #1!
