What Factors Should You Consider Before Growing Weed

Start your marijuana cultivation journey with thoughtful planning. Consider these factors when starting to grow marijuana.

Indoor vs. Outdoor Growing

Indoor cultivation provides a controlled environment, allowing you to manipulate light, temperature, and humidity. This control can result in higher-quality buds but requires an initial investment in equipment like grow lights and ventilation systems.

Outdoor cultivation relies on natural sunlight and can yield larger crops due to the unlimited space and natural conditions. However, it’s essential to consider your local climate and potential pests or diseases that may affect your plants.

Strain Selection

Choosing the right strain when growing cannabis is a pivotal decision in your cultivation journey. Each strain offers unique characteristics regarding habitus, flavor, potency, and effects. Whether you prefer the relaxing effects of an Indica or the energizing buzz of a Sativa, research and select a strain that aligns with your preferences and growing conditions.

Cultivation Space

Assess your cultivation area before choosing your cultivar. This will allow you to choose a strain best suited for your space. You can then germinate enough seeds to properly fill a room, tent or closet without overcrowding

Legal Regulations and Local Laws

Before diving into cultivation and cannabis growing, familiarize yourself with the legal landscape of marijuana in your area. While some regions permit personal cultivation, others have strict regulations or outright bans. Understanding the legal implications ensures you stay compliant and avoid potential legal issues.

Soil and Nutrients

Decide what type of cultivation method suits your space and personal style. Soil is a great place to start, and choosing a high quality soil and organic nutrients will benefit both you and your plants, helping to develop terpenes and depth of flavor. Many indoor cultivators opt for soil-less substrates such as rockwool or coco, this allows for more precise feeding cycles and monitoring.

Watering and Maintenance

Consistent watering and maintenance are crucial for healthy plant growth. Overwatering or underwatering can lead to nutrient deficiencies or root rot. Develop a watering schedule and regularly monitor your plants to ensure they thrive.

Pest and Disease Control

Pests and diseases can wreak havoc on your cannabis plants if left unchecked. Implement preventive measures such as regular inspections, proper ventilation, and organic pest control to protect your plants from threats like spider mites, aphids, and powdery mildew.

Harvesting and Curing

Knowing when and how to harvest your buds is essential for maximizing potency and flavor. Additionally, curing your harvested buds properly enhances their aroma and smoothness. Familiarize yourself with the signs of readiness for harvest and proper curing techniques to enjoy the best possible end product.

How to Grow Marijuana

Germinating Marijuana Plants

Starting with germination, you have a couple of options. The paper towel method remains a favorite among many growers. Place your seeds between two damp paper towels and keep them in a warm, dark place – preferably inside a ziplock bag (partially zipped).

This will help increase humidity and prevent germinated seeds from accidentally drying out. Then check daily, ensuring the paper towels remain moist until you see the seeds sprout.

Alternatively, plant your seeds directly into a seedling tray filled with pre-moistened soil, covering them lightly with a thin layer of soil.

Seedling Stage

Once your seeds have sprouted, they enter the delicate seedling stage. During this phase, handle them with care, ensuring they receive gentle light (avoid direct sunlight, as it may harm young plants). A sunny window can suffice, but if natural light is limited, consider using grow lights and seedling heat mat designed for young plants. Water lightly, aiming to keep the soil consistently moist but not waterlogged.

Vegetative Stage

The vegetative stage is a time of rapid growth. Your plants will begin to develop leaves, branches, and stems as they prepare for flowering.

To support this vigorous growth, provide them with 18+ hours of light daily. Alongside light, feed them a balanced nutrient solution rich in nitrogen to promote healthy vegetative growth.

Flowering Stage

As your plants mature, they naturally transition to the flowering stage when grown outdoors. For indoor cultivation, growers will need to restrict light from 18/6 to 12/12.

This phase requires a change in light cycle to 12 hours of light and 12 hours of darkness to induce bud production. Monitor your autoflowering plants closely, as this is when they’ll require extra care and attention to thrive and produce high-quality buds.


Determining the right time to harvest is crucial for potency and flavor. Look for signs of maturity, such as cloudy and amber trichomes and vibrant pistils. Typically, growers will de-leaf the plants and harvest them whole, allowing the drying process to take place before manicuring and separating the buds.

This method helps maintain the shape and appearance of the buds, avoiding unsightly flat spots that can occur with wet trimming. It also helps to slow the drying process, leading to a smoother smoke.Handle the plants gently to preserve the integrity of the trichomes during this process.


After harvesting, proper drying is essential to prevent mold and preserve potency. Hang your whole, de-leafed plants upside down in a dark, well-ventilated room with a standard temperature 60°F (15°C) at 60% humidity.

Allow them to dry for 7-10 days, checking regularly until the stems snap rather than bend. Once dried, you can then proceed with trimming and manicuring the buds to achieve the desired final product.


Curing is a critical step to enhance the flavor, aroma, and smoothness of your buds. Place your dried buds in glass jars, filling them about 3/4 full to allow for air circulation. Store the jars in a cool, dark place, opening them daily for the first week to release excess moisture.

Curing for at least 2-4 weeks will yield the best results, and opening the jar lid (burping) to release the fermenting gasses once a week, improves the overall quality of your buds.


Once cured, it’s time to store your buds for long-term preservation. Transfer them to airtight containers, such as glass jars with tight-sealing lids. Store these jars in a cool, dark place away from direct sunlight and moisture to maintain their freshness, potency, and quality for extended periods. Proper storage ensures you can enjoy your homegrown cannabis at its best whenever you choose to indulge.

What Equipment Do You Need?

Grow Lights

LEDs, HIDs or just a sunny spot in your yard provide essential light spectrums for growth. Choose based on your budget, available space, and personal preference.

Growing Medium

Soil remains a popular choice due to its simplicity and natural nutrient content. However, supplemental nutrients will still be required to ensure optimal plant health and growth. Alternatively, consider coco coir for a soilless option that retains moisture well and promotes robust root growth.

Hydroponic systems offer direct nutrient uptake but require precise management to maintain the correct nutrient balance and pH levels.


These are essential for plant growth and must be tailored to the specific needs of cannabis. Look for nutrients designed for cannabis cultivation, with differing NPK (Nitrogen, Phosphorus, Potassium) values appropriate for each life stage.

During the vegetative stage, higher nitrogen levels are beneficial, while the flowering stage requires nutrients with lower nitrogen and higher phosphorus and potassium levels. Using the correct nutrient formulations at each growing stage is crucial to avoid impeding bud production and ensure healthy plant development.

Ventilation System

Proper ventilation helps regulate temperature and control humidity but does not entirely prevent issues like mold or mildew. Ventilation and environmental control are linked but distinct.

Use exhaust fans, intake fans, and ducting for effective air circulation. Consider also using an air conditioner to control heat and some humidity, and a dehumidifier if necessary.

Effective air circulation helps reduce microclimates around plant leaves, minimizing the potential for mold and mildew, but it doesn’t fully prevent these issues.

pH Meter

Monitor pH levels to ensure nutrient absorption. Cannabis prefers slightly acidic conditions. Adjust pH as needed for optimal growth.

Containers or Pots

Choose pots with good drainage to prevent waterlogging. Fabric pots encourage air pruning and healthier root development.

Pruning Shears

Pruning shears are essential for plant health and higher yields when used correctly. Pruning at specific intervals, rather than constantly, can improve airflow, redirect energy to buds, and minimize plant stress.

Over-pruning can negatively impact plant health, as cutting any part of your plant is stressful. There are low-stress training techniques that do not involve cutting, which can also be effective.

When done properly, cannabis can respond well to pruning, but this process is classified as “high-stress.” Invest in sharp, clean shears for precise cuts.

pH Up and pH Down Solutions

pH Up and pH Down solutions fine-tune water or nutrient pH. pH Up raises levels, and pH Down lowers them. Maintain optimal conditions for nutrient absorption by having both solutions ready.


Use a reliable timer for consistent grow light cycles. During flowering, maximize yields with a set schedule. Peace of mind comes from automated lighting cycles.

Thermometer and Hygrometer

Maintain an ideal growth environment with a thermometer and hygrometer. Aim for 70-85°F (21-29°C) temperatures and 40-60% humidity. Regular monitoring ensures thriving plants.

Tips for Growing Cannabis Seeds

Start with Quality Seeds

The foundation of successful growth begins with quality seeds, starting with healthy and viable genetics. Investing in quality upfront increases the likelihood of robust plants thriving throughout their lifecycle.

Maintain Proper pH Levels

Consistency in pH levels is vital for effective nutrient absorption by your cannabis plants. Aim for a slightly acidic pH level, typically between 6.0 and 6.8 for soil growth and 5.5 and 6.5 for hydroponic setups. Regularly check and adjust pH levels using pH testing kits or meters to prevent nutrient lockout and encourage healthy growth.

Water Properly

Proper watering techniques are essential to avoid common pitfalls like root rot or nutrient deficiencies. Water your cannabis plants when the top inch of soil feels dry to the touch, allowing for adequate oxygenation of the roots. Ensure your containers have sufficient drainage holes to prevent water accumulation, which can lead to root problems.

Monitor Temperature and Humidity

Optimal temperature and humidity are critical for robust plant growth and resin production. Aim for a temperature range of 68-77°F (20-25°C) during the day and slightly cooler at night.

Humidity levels should be around 40-60% during vegetative and 40-50% during flowering. Utilize thermometers and hygrometers to monitor conditions and consider using fans for air circulation, and consider using A/C and dehumidifier to maintain ideal humidity levels.

Prune Regularly

Regular pruning is essential for promoting plant airflow, reducing pests and diseases risk, and directing energy towards bud production. Focus on removing dead or yellowing leaves and thinning out dense foliage to create a more open and light-penetrable canopy, leading to healthier and more productive plants.

Use Nutrients Wisely

Ensuring your plants get the right nutrients is important to helping them grow big and healthy. But it’s not just about giving them food, you need to use the right ones wisely!

Overdoing it with nutrients can do more harm than good, causing problems like nutrient toxicity. That’s why using the right mix of nutrients, like nitrogen, phosphorus, and potassium, is important. These are essential for your plants, helping them grow strong and healthy.

Follow the instructions carefully for the nutrients. A good idea is to start with half the recommended dose to see how your plants react, as some cultivars can be more sensitive than others. Then, gradually increase to the recommended dose as needed.

Keep a close eye on how your plants are doing to make sure they’re happy and healthy. Homegrown Cannabis Nutrients are a great option for your plants’ health and growth.

Control Pests and Diseases

Proactive pest and disease management are essential to safeguard your crop when growing marijuana seeds. Regularly inspect your marijuana plants for signs of pests or diseases and implement preventive measures such as neem oil treatments, insecticidal soaps, or introducing beneficial insects like ladybugs or predatory mites. Cleanliness and proper ventilation also play a vital role in preventing fungal diseases.

Be Patient

Patience is a virtue in cannabis plant cultivation. Each growth stage, from germination to harvest, requires time and attention. Resist the urge to rush or make hasty decisions, as this can lead to mistakes or suboptimal results. Trust the process, adhere to best practices, and savor the experience of nurturing your cannabis plants to maturity.

Educate Yourself Continuously

The realm of cannabis cultivation is continually evolving, with new techniques, strains, and research emerging regularly. Dedicate time to educate yourself through books, online forums, tutorials, and connecting with fellow growers. Continuous learning enhances your skills and equips you to adapt to new challenges and innovations.

Harvest at the Right Time

Timing your harvest correctly is paramount to maximizing potency, flavor, and yield. Use a jeweler’s loupe or microscope to examine trichomes on the buds. Look for a milky-white appearance with some amber trichomes for peak THC levels and a balanced high. Harvesting too early or too late can diminish the quality and potency of your final product, so patience and careful observation are key.
