When your marijuana plant becomes a seedling, you’ll notice it developing more of the traditional cannabis fan leaves. As a sprout, the seed will initially produce leaves with only one ridged blade. Once new growth develops, the leaves will develop more blades (3, 5, 7, etc.). A mature cannabis plant will have between 5 or 7 blades per leaf, but some plants may have more.
Cannabis plants are considered seedlings until they begin to develop leaves with the full number of blades on new fan leaves. A healthy seedling should be a vibrant green color.
It’s important to know these stages and how long each lasts to know what the plant needs and when. Knowing where your cannabis plants are in their life cycle will dictate when to prune, train, and trellis your plants, and when to harvest.
Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.
Even if growing outdoors, a lot of growers will start their seeds inside under an artificial light to help them through this delicate stage of marijuana growth.
As roots develop, the stalk will rise and you’ll begin to see the first iconic fan leaves grow, at which point your cannabis plant can be considered a seedling.
As the sun reaches up high in the sky, your cannabis will want to as well. Make sure all of your plants are outside by the Summer Solstice.
From the desert states of Arizona and New Mexico to the more tropical regions such as the Carolinas and Florida, these states benefit from lots of sunshine and warmer weather. In these states, the key to growing cannabis outside in pots is to plant on the earlier side if you’re organized early enough. Place your pots outside as early as March, although April is fine too.
Growing in pots, in general, makes the process of growing anything easier, since you can move your plants around (between indoors and outdoors) during undesirable weather developments. On top of that, a Pot for Pot also provides the nutrients as well as the best soil for growing cannabis outside. Our simple, easy-to-follow process is literally the best way to grow cannabis outside. This is true whether you are growing for the first time or want to make growing cannabis outside in pots as effortless as growing any other plant.
A Pot for Pot, on the other hand, makes planning and executing a marijuana home grow super simple. The Complete Grow Kit provides just about everything you need to nurture a successful plant in as few as 80 days. All that’s left for you is selecting your seeds, adding some water, and providing plenty of sunshine.
For those who have not gone through the process of growing “normal” photosensitive plants, the difference is huge. Photosensitive plants will not even enter their flowering phase until the hours of uninterrupted darkness reach a certain length. This must be consistent every night for several weeks to be successful. If even a flashlight or streetlight interrupts this darkness, the cycle is interrupted, and it takes that much longer to reach the point of entering the flowering phase.
States that are higher altitude and/or have colder winters, such as Colorado, Montana, the Midwest, and the Northeast, also benefit from the shorter growing season of autoflowering plants. The best time to plant might not be until April or May, and that’s okay; the plants will still be ready to harvest before the weather starts getting too cold. In general, it should be safe to bring your plants outside by the time the end of April rolls around. This applies to the majority of states in the North, although you might want to bring them indoors at night when the risk of nighttime frost still exists.
The length of time needed to go from seed to harvest varies hugely depending on the strain. This is because genetics can be extremely different depending on the dominant strain, whether it is a hybrid, and whether it is photosensitive or autoflowering. Besides that, the grower’s own behavior can make a difference as well. If you plant earlier in the season, a photosensitive plant will take longer to reach harvest. If you plant later in the season, it will take less time. Of course, this will only work if the plant has been given enough time to properly grow, especially during the vegetation and flowering phases.
That is why autoflowering strains are some of the best cannabis strains to grow outside. They will grow correctly even if they are exposed to a little light during the night. Their straightforward growing process is perfect for those already busy with day jobs or other hobbies who simply want to grow some high-quality cannabis plants on the side. If this applies to you, autoflowering seeds growing in a Pot for Pot are likely an excellent solution.
If you live in a place that has a constant good weather then the season isn’t very important to take into consideration for you to plant marijuana seeds outdoors. In places with less abundant sunshine, the season would last roughly from March to August or September depending if it’s an Indica or a Sativa marijuana plant. In other regions such as equatorial or coastal regions, the issue of when to plant marijuana seeds outdoors is non-existent since the constant warmth and humidity will germinate the marijuana seeds outdoors without any worries of the conditions being too harsh for the seedlings, or not enough humidity and warmth for the marijuana seed.
You’re not the only one wondering when to plant Marijuana seeds outdoors. Although it is a question that doesn’t have only one answer. Depending on what part of the world you live, the ideal conditions to plant marijuana seeds outdoors would be in the spring, between March and May (in the northern hemisphere). Ideally, during this time, your marijuana seeds should already be germinated and you can even plant marijuana seedlings that are a few weeks old outdoors. As we have mentioned in our other guides, to plant marijuana seeds outdoors is a numbers game. The more marijuana seeds you plant outdoors (if you don’t have the experience) the better your germination rates and eventual harvest will be. For Northern hemisphere climate conditions we don’t recommend to plant marijuana seeds outdoors, rather germinate and start growing the marijuana plant indoors until the weather conditions are ideal to take the marijuana plant outdoors.
