How long to grow marijuana indoors

Sticking to that schedule is key, he added. “Say you’re at day 30 of the flowering cycle and you come into that closet when it’s supposed to be dark and turn a bunch of lights on. You’re going to throw the whole cycle off and that’s the end of that. It only takes 10 seconds.”

Space: 3 x 3 x 5 feet, minimum. “The bigger the space, the better. With all the lights, closets get hot,” Lipton said. That said, closets help growers control light pollution when the plant is in its flowering cycle — one of the main reasons home growers favor them over larger spaces, such as living rooms. “If you have a spare bedroom, or a basement even, you can just use that and close the door,” Lipton said.

To harvest, many growers begin by removing the leaves of the cannabis plant with trim scissors, followed by the buds (using pruners). “We call this bucking,” Lipton said. “Gloves are also extremely important for sanitation reasons as well as to keep your hands from becoming sticky with the resin from the plant.”

Relative humidity: 30 to 45 percent. “If you live somewhere humid, you’re probably going to want to buy a dehumidifier,” said Lipton. “In Boulder, we sometimes have to add humidity.” At home, that can be done with a reliable humidifier.

Trigger the flowering cycle.

pH of Water: 6.3 to 6.7. “You’ll need a meter that you can stick into your water and tell you the pH,” Lipton said. “You want something between 6.3 to 6.7 pH for watering your plants. That sounds like pretty sophisticated stuff but it’s really not. A lot of times your tap water will be 7.8. You can use what they call pH down. That’s a crucial step.”

The last step involves curing the bud. “Curing is just as important as the growing process,” Lipton added. “We do a slow cure, which means that it takes anywhere from three to six weeks depending on variety.” Temperature and humidity play a large role during cure and must be maintained to ensure a great final product. “Our actual cure process is somewhat of a secret, so I cannot share the fine details,” Lipton said. “But it’s an art form and extremely crucial to our success.” The reason growers cure bud after harvesting is that it creates a smoother smoke and increases its potency. Detailed recommendations for proper curing can be found online, here and here.

Though the 12-hour interval is fairly universal, knowing exactly when to induce flowering is less clear. For the home grower, it usually comes down to space; the longer one waits to trigger the flowering cycle, the taller their plant will be. A good rule of thumb: cannabis will only continue to grow 30 to 50 percent once the light source is reduced. If the plant is growing in a closet, growers should trigger the flowering cycle, understanding that there must be more than two feet of space between the canopy of the plant throughout the entirety of its life.

Find a healthy clone.

Before someone even begins to consider the genetics of their preferred strain, they should first ensure that their apartment is cannabis-friendly. There are five main factors to consider: space, temperature, humidity, the pH of water, and the amount of light.

“Growing cannabis in tight spaces is not my usual recommendation,” said Stephen Lipton, the cultivation manager at The Farm Recreational Marijuana Dispensary, an award-winning recreational facility in Boulder, Colorado, specializing in what it calls “craft cannabis.” At any given time, Lipton oversees close to 15,000 plants across seven different facilities in Boulder County. “If you have a really tight space and it gets too hot or too humid, you’re going to have big trouble.”

This is an important thing to consider before you begin: think about the power requirements and the overall size and scale of what you want to build. We recommend starting small if you are independent in order to get it right and get a feel for how the process works before you begin to scale up.

They also have short flowering stages, which makes them a popular choice for experienced cannabis breeders or anyone who wants a quicker cycle. Indoor growers enjoy raising them because their shorter flowering periods mean they can produce more per year, while outdoor growers can cultivate them without worrying about climate issues or early winters. On average, Indica strains have a flowering state that lasts 8 to 12 weeks.

Overall, the time it takes to flower cannabis depends on the strain of weed you are attempting to grow and the method you are using. If you want to grow Sativa strains, you may want to brace yourself for a longer haul, while Indicas will flower much more quickly. As you progress in your grow skillset, try combining strains in order to get the most out of your grow times and the seasons of the year.

Hybrids are the result of crossing Indicas with Sativas. While some prefer to cultivate either pure Indica or pure Sativa strains, most growers are cultivating hybrids due to the interesting and fun variants that are produced.

Understand The Scale Of Your Grow

Hybrids grow quickly during the vegetative stage just like Sativa strains but have shorter flowering periods which is common in most pure Indica strains. Hybrids have an average flowering time of 6 to 10 weeks until they are ready to be harvested.

Whichever method and strain you go with, good luck and have fun!

Be prepared to spend a significant amount of money when planning to grow weed. Buying quality marijuana seeds is not a cheap investment, and you’ll also need to invest in decently expensive equipment as well.

Hybrid Grow Time

Indicas can be easily spotted because they are pretty much the opposite of Sativas as far as appearance. The flowers of Indica plants are typically shorter and stubbier than their tall, thin counterparts.

Within the flowering stage, there are three subphases:

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.

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.

If you’re growing outdoors in the Northern Hemisphere, growers usually get their seeds between February and April, and you should start your seeds by the end of April. Some growers will start their seedlings inside in a more controlled environment because seedlings are more delicate, and then put their seeds in the ground outside once they’re a little bigger. If you’re growing clones or autoflowers, you have a grace period of another month or so. Plants usually need to be outside, in the ground, by the end of June.

Flowering stage

Marijuana light cycle: 16 hours a day

Cannabis plants go through a series of stages as they grow and mature, and those different growth stages call for different amounts of light, nutrients, and water.

Marijuana light cycle: indoor—16 hours a day; outdoor—at least 6 hours of direct sunlight (“full sun”), plus several hours indirect sunlight

What are a weed plant’s growth stages?

If you’re growing indoors, you can force a weed plant to flower after only a few weeks when it’s small, or after several weeks when it’s big. If you’re growing outdoors, you’re at the whim of the seasons and will have to wait until the sun starts to go down in fall for it to flower and then to harvest.
