When Should Growers Plant Outdoor Cannabis Seeds for 2023

When to start outdoor cannabis seeds

The optimal time to plant cannabis seeds depends on various factors such as the climate and growing conditions of your specific location.

Typically, outdoor cannabis plants are planted in the spring after the last expected frost date in your area. In indoor setups, growers can plant seeds at any time, but it is best to do so when they have the resources and setup to provide the proper environment for seedling growth.

It is important to research the specific strain you are planting, as different strains have different growth habits and requirements. It is also a good idea to consult local growers or gardening resources for more information on the best time to plant in your area.

Importance of Timing for Growing Outdoor Cannabis

Timing is critical for growing outdoor cannabis, as it greatly affects the quality, yield, and potency of the final product. Proper timing helps ensure that the plants receive the right amount of light, water, and nutrients, which are essential for healthy growth and development.

For example, if the seeds are planted too early or too late in the season, they may not receive enough light and warmth to germinate and grow properly. On the other hand, if the seeds are planted at the right time, they can take advantage of the optimal growing conditions, which can result in a bountiful harvest.

Additionally, timing is also important for avoiding potential problems and pests that can damage the plants. For example, planting too early in the season can put the plants at risk for damage from frost or cold weather, while planting too late may result in a shortened growing season and reduced yields.

Therefore, it is crucial for growers to understand the best time to plant their outdoor cannabis seeds, taking into consideration factors such as the local climate, the length of the growing season, and the type of seeds being used. By following these guidelines, growers can maximize their chances for success and produce high-quality cannabis crops.

Starting Cannabis Seeds Indoors

Starting cannabis seeds indoors can be a great way to control the growing environment and ensure that your plants get off to a strong start. Here are the steps to starting cannabis seeds indoors:

  1. Choose the right seeds: Choose high-quality, feminized cannabis seeds that are well-suited to indoor growing.
  1. Prepare the soil: Use a good-quality seed-starting mix and sterilize it to prevent the growth of mold or bacteria. Fill small containers, such as peat pots, with the soil mix.
  1. Plant the seeds: Place one seed in each container, about a quarter inch deep. Lightly cover with soil and water well.
  1. Provide heat and light: Cannabis seeds need warmth to germinate, so place the containers in a warm, bright location. You can also use a heat mat to provide bottom heat. A grow light can also be used to provide the right spectrum of light for seedling growth.
  1. Keep the soil moist: Water the cannabis seeds regularly to keep the soil moist but not waterlogged.
  1. Monitor seedling growth: Watch for signs of growth, such as the emergence of seed leaves, and adjust the growing conditions as needed.
  1. Transplant the seedlings: Once the seedlings have a few sets of true leaves, they can be transplanted into larger containers or into your growing setup.

Starting cannabis seeds indoors can be a rewarding and enjoyable experience, but it does require patience and attention to detail. By following these steps, you can give your plants the best possible start and ensure a successful harvest.

Is it Better to Start your Outdoor Cannabis Seeds, Indoors?

Starting your outdoor cannabis indoors can have some advantages, but it also has some drawbacks.


  1. Control: Starting cannabis seeds indoors gives you more control over the growing environment, including temperature, light, and humidity levels.
  1. Protection: Indoor growing can protect your plants from environmental stressors such as pests, disease, and extreme weather conditions.
  1. Early start: Starting your cannabis seedlings indoors can give you a head start on the growing season and allow you to harvest earlier in the year.


  1. Cost: Starting cannabis seeds indoors requires investment in equipment such as grow lights, heating and cooling systems, and containers.
  1. Space: Indoor growing can be space-intensive, especially if you are starting multiple plants.
  1. Transfer shock: Transplanting seedlings from indoor to outdoor conditions can cause stress to the plants, which can impact growth and overall health.

Ultimately, whether or not it is better to start your outdoor cannabis indoors will depend on your specific situation, including your resources, temperature, climate, and growing goals. Some growers prefer to start their plants indoors and then transplant them outside, while others prefer to start their plants directly in the ground. It is important to consider the advantages and disadvantages of both options and choose the one that works best for you.

What are Gardening Zones and Why They are Important to Outdoor Cannabis Crops?

Gardening zones, also known as hardiness zones, are areas defined by the USDA based on average annual minimum winter temperatures. They provide a useful guide for gardeners and farmers to determine which plants are likely to thrive in a specific location.

The USDA Plant Hardiness Zone Map is divided into 13 zones, ranging from zone 1a (with average minimum winter temperatures of -60 to -65°F) to zone 13 (with average minimum winter temperatures of 50 to 60°F). Within each zone, the minimum winter temperature is 10°F warmer or colder than the adjacent zones.

Knowing your cannabis gardening zone can help you choose the right cannabis plants for your location, as different strains have different hardiness requirements. For example, if you live in a cooler zone, you may want to choose cannabis strains that are known to be cold-hardy, while if you live in a warmer zone, you may want to choose heat-tolerant plants.

It is important to note that gardening zones are not the only factor to consider when choosing plants, as other factors such as sunlight, rainfall, and soil type also play a role in plant growth and success. Nevertheless, gardening zones can be a useful starting point for determining which strains are most likely to thrive in your area.

How Big Do You Want Your Outdoor Cannabis Plants?

So, this may go without saying but the sooner that a grower starts their outdoor cannabis seeds indoors the larger that plant is going to be when transplanted outdoors. If you only have a certain amount of room in that outdoor garden, then you will need to balance the time from when you start your seeds to harvest. 

If you start your seeds in February for the northern hemisphere, they can be up to two to three feet tall by the time you transplant them outside in April or May. Growers should keep in mind that over the summer months your cannabis plants can grow up to 20 to 30 times larger by the time they are ready for harvesting in October or November of that growing season. 

The Importance of Timing When Starting Seeds for the Summer Season

When starting cannabis seeds for the summer, timing is very important for most growers. First growers will not want their plants to grow too large indoors before they are able to transplant cannabis outdoors. You will require a large enough light to keep them growing healthy while they are still growing indoors before transplanting. Growers will want to be able to support the plant until it can be moved outdoors. 

For example if you were to start your seeds in February, but you were unable to transplant outdoors till May 21th and your plants are 3 feet in height. Will you be able to support three foot high plants with your lighting, pot size, soil needs and fertilizers? If not then it may be wise to start your plants in March and have them only be 2 feet high or April and be 1 foot in height at the time of transplant. 

The same can be said when moving the plants outdoors in the spring, they will grow very large outdoors, if they are 2 or 3 feet tall at the time of transplanting. Do you need to keep your plants under a certain height for security reasons? Sure you could trim or prune the cannabis plants but this is also extra work on the growers part. Also it is important to consider if the plant sizes can be accommodated. Does your outdoor growing area have the ability to support very large cannabis plants? Some cannabis strains such as sativas can grow up to 15 to 16 feet and just as large width wise.
