PLANTS When it comes to growing cannabis, there are two options: indoor and outdoor cultivation. Outdoor growing is cost-effective as nature provides the necessary elements for growth, such as sunlight. However, there are also potential risks of theft, pollination, pest infestations, and damage from wild animals. Indoor growing, on the other hand, requires more equipment and maintenance but offers complete control over the growing environment, including lighting and temperature.

When deciding on a growing location, consider the following best practices: -Start with a small grow operation, especially if you are a first-time grower. -Maintain a clean and organized grow space from seed to harvest. -Ensure that the area is light-tight to prevent escape of light. -Maintain the proper temperature, humidity, and airflow for optimal growth. -Consider the cost of electricity as it can be high for indoor growing, especially for large-scale operations. -Keep the setup costs within your budget.



When it comes to growing cannabis, there are a variety of mediums to choose from. Here are a few options to consider:

SOIL: This is the most traditional and popular medium for growing cannabis. It's easy to find and comes with its own set of nutrients. Additionally, cannabis grown in soil tends to have a more robust flavor and aroma. However, it's important to use high-quality potting soil and supplement it with specialized nutrients for optimal growth.

SOILLESS: A soilless medium, such as coco coir, vermiculite, or perlite, can lead to faster growth and larger yields. However, you will need to provide all the necessary nutrients yourself.

HYDROPONICS: This method of growing cannabis involves using a hydroponic system and providing the plants with nutrients directly. This can result in faster growth, bigger yields, and increased potency. However, it's important to do your research and choose the right system and nutrients for your setup to avoid any issues.



Similar to other plants, cannabis plants require nourishment to thrive. The key is to understand the appropriate type of nutrients to use based on the growing medium: soil, soilless, or hydroponics. Each medium has specific nutrients designed for optimal growth, and using the incorrect type can impede the plants' development. Utilizing marijuana nutrients is simple, as long as you strictly adhere to the nutrient-feeding chart and instructions provided. However, it's important to ensure that the plants can absorb the nutrients through their roots. Additionally, maintaining the appropriate pH level of the root environment, particularly if using liquid nutrients, is crucial. The pH level should vary depending on the growing medium. For soil, the pH should be between 6.0 to 7.0, while for hydroponics it should fall between 5.5 and 6.5. Adhering to these guidelines can lead to denser buds and larger yields for your cannabis plants.


Are you new to growing marijuana? Don't fret, there are options that cater to beginners like you. Have you heard of autoflowering cannabis seeds? These seeds do not require a specific lighting cycle to induce the flowering stage, thus saving you money on lighting costs. Additionally, autoflowering strains have a shorter flowering time, which means less maintenance for you. Another great choice for beginners is feminized seeds. These marijuana seeds produce only female plants, eliminating the need to identify and separate male plants. We highly recommend choosing cannabis seeds that possess both autoflowering and feminized characteristics for a hassle-free and successful growing experience.


As a weed grower, it is crucial to understand that during different growth stages, cannabis plants require varying levels of light. Indoor growers, in particular, should pay close attention to this as outdoor growers do not have to worry about it.

During the vegetative stage, plants should receive 18 hours of light per day, before switching to a 12-hour lighting cycle to trigger the flowering stage. Ensure that your lighting system is tight enough to prevent light leakage during the dark periods, as this can impact the growth stages of your plants, causing them to revert to a different stage or produce male buds.

There are several types of cannabis grow lights to choose from, including HID, fluorescent, LED, and induction lights. HID lights, such as metal halide (MT) and high pressure sodium (HPS), are the industry standard and are commonly used by many growers. However, they generate a lot of heat and require air-cooled reflector hoods, especially in small spaces with limited ventilation. Fluorescent lights are a cheaper option and produce less heat, but they are less efficient and produce 30% less light per unit of electricity used than HID lights. LED lights, although more expensive, generate less heat, last longer, and use less electricity, resulting in higher-quality yields. Induction lights, such as plasma and magnetic, can support both vegetative and flowering stages but plasma induction lights are not recommended by expert growers as they have inadequate parts of the light spectrum to sustain healthy growth.



Indoor growing requires close monitoring and control of environmental conditions in order to ensure healthy plant growth. This includes factors such as humidity, airflow, and temperature. It is essential to take into account any potential issues that may arise from the location of your grow space, such as a damp basement or excessive heat.

To combat these issues, it may be necessary to install equipment such as heaters, dehumidifiers, AC units, or extra fans to maintain optimal growing conditions. Additionally, it can be helpful to manipulate the timing of your lights to work with the natural temperature fluctuations of your environment. For example, turning your lights on in the evening when it's cold outside and turning them off during the day when it's hot can help to regulate the temperature in your grow space. It is important to note that this strategy may also require adjusting your grow schedule to only work on your plants during the hours when the lights are on, likely at night.


When it comes to growing weed indoors, the type of container you choose for your plants can have a significant impact on their growth and development. There are a variety of options available, from ceramic pots and fabric containers to traditional plastic containers, but it's important to select a container that is suitable for your specific weed needs, taking into account factors such as plant size, density, and rooting system requirements.

When selecting a container, consider the following important factors:

  • Nutrients: To ensure optimal nutrient absorption and avoid nutrient deficiencies, your container should allow for the right temperature and soil PH levels.

  • Oxygen: Proper oxygenation is crucial for a strong rooting system, so make sure your container is perforated appropriately to allow for adequate oxygen flow.

  • Drainage: Proper drainage is essential to prevent waterlogging and root rot, but your container should also retain water to keep your plants hydrated.

  • Space: As roots branch out and develop, it's important to choose a container that provides enough room for growth, otherwise, the plant may become choked and stunted.

When germinating seeds or transplanting seedlings, it's important to keep these factors in mind to ensure that your container can sustain a thriving root system. Not only will this ensure optimal growth and development, but it will also help to ensure a high-quality yield.
