How Long Does It Take To Grow Marijuana

There are a lot of factors that go into growing weed. The time it takes to grow marijuana depends on the genetics of the plant, the lighting used and environmental conditions.

There are three main factors that determine how long it takes to grow weed#

There are three main factors that determine how long it takes to grow weed: genetics, lighting and environmental conditions.

Genetics are important because they determine how fast the plant grows. The same genetics will always produce the same results which means you can use your previous experience with a strain to predict how long cannabis might take to grow in your current setup.

Lighting is important because it determines the amount of energy the plant has to grow. More light = more growth! As you increase or decrease light levels, so too does your cannabis get faster or slower with its flowering cycle.

Genetics#

Genetics is the most important factor in determining how long it takes to grow marijuana. They also determine the size and shape of your plant, as well as how quickly it will mature. For example, sativa-dominant strains are known for taking longer to flower than indica-dominant strains because of their larger size.

Lighting#

The amount of light that a plant receives is crucial for its growth. The amount of light that a plant receives is determined by the type of light used, and the amount of time that the light is on. For example, if you use fluorescent bulbs or high-pressure sodium (HPS) lights, which are both low-intensity lights, then your plants will need to be in an environment where they receive at least 18 hours of light per day. These conditions can be achieved by placing your plants in an indoor grow room where they receive natural sunlight through windows or skylights during the day and artificial lighting at night.

If you use metal halide (MH) bulbs or high output fluorescent (HO) lights as well as HPS bulbs, which are both more intense than the previous types, then your plants will need to be exposed to 24 hours worth of artificial lighting every day in order for them to grow properly.

Environmental conditions#

• Temperature and humidity. A cannabis plant’s optimal growing environment is a greenhouse kept at temperatures between 70˚F and 80˚F (21˚C – 27˚C), though it can survive temperatures as low as 50˚F (10˚C) for short periods of time. Humidity levels should be kept between 40% and 60%. Higher humidity encourages faster growth, but too much moisture in the soil can cause root rot or fungus that affects both the plant’s health and yield.
• Air circulation. Plants need to breathe, so make sure there’s plenty of air circulation around them while they’re growing! If your space doesn’t have good ventilation already, try opening windows or using fans to encourage healthy airflow. This will help prevent mold from growing on plants’ leaves—another reason why keeping humidity levels low is essential when growing marijuana indoors!
• Watering frequency & fertilizer use: You’ll need to water your plants every 2-3 days when they’re in their vegetative stage; once they enter their flowering phase (which occurs several weeks after sprouting), watering should happen only every 7-8 days until harvest time approaches because less frequent watering leads to higher THC content in buds.* Fertilizer: Fertilizers are available both commercially through stores like Home Depot or Lowe’s Garden Centers; however these may contain harmful chemicals such as nitrogen which could kill off pests lurking inside pots of soil bought from these companies.* Pest control methods: When dealing with insects like spider mites or whiteflies look for natural remedies like neem oil which won’t harm humans but will kill off unwanted bugs.* Soil type used during germination process

• Genetics: The genetics of your plants will determine how quickly they grow. If you’re using seeds from a clone or seed bank, then you can expect them to do as well as their parents did. If you’re using seeds from regular marijuana grown outside, then there is no guarantee of how fast it will grow.
• Lighting: The more powerful your lights are and the closer they are to your plants, the faster they’ll grow. You can get some great results with LED lights if you have enough space in your home or apartment (they don’t need much room). There are also HID systems which use bulbs that give off much more heat than LEDs do so make sure before investing in one that there’s enough ventilation available nearby where these kinds of lights would be placed because otherwise things like mold might start growing on them due to excess heat/humidity buildup inside your house which could then lead into toxic fumes being released into whatever open spaces may exist nearby (like through doors/windows).
• Environmental Conditions: Lastly but not leastly comes temperature control during periods when daylight hours aren’t sufficient enough for adequate growth such as winter months when nights aren’t long enough for consistent light exposure throughout all day long without interruption due lack thereof sunlight streaming down onto earth surface area each morning sunrise hour since this would result less sunlight reaching earth surface level during mornings hours only leaving us with less chance at seeing brighter days ahead instead all

The bottom line is that it depends on the genetics of your plant, the lighting and environmental conditions. The best way to find out how long it takes for your plants to grow is by experimenting with different strains and methods until you find something that works well for you.
