Marijuana Grow Tutorial

Whether you're new to weed production or looking to improve your existing harvest, following this complete guide will help you produce large, high-quality yields right at home. With the right gear, strategies, and attention, cultivating cannabis indoors can be an extremely satisfying and cost-effective endeavor.

Choosing Marijuana Varieties

The first step in planning your indoor harvest is picking the right cannabis strains to cultivate. The three main types of weed plants each have their own traits.

Energizing strains

Known for their uplifting mental effects, these strains grow tall and slender with narrow leaves. They thrive in warmer equatorial climates and have a longer flowering time between 10-12 weeks indoors. Top sativa varieties include Jack Herer, Durban Poison, Super Lemon Haze, and Jack Herer.

Relaxing strains

These strains provide calming full-body effects and grow short and bushy with wide leaves. Accustomed to colder mountain climates, they bloom faster within 2-2.25 months. Popular relaxing varieties include Northern Lights, Bubba Kush, and Bubba Kush.

Mixed strains

Mixed varieties mix traits from both energizing strains and relaxing strains. They offer blended effects and have medium blooming times around 9-10 weeks. Well-known hybrids are OG Kush, Girl Scout Cookies, and Blue Dream.

Setting Up Your Grow Space

Cannabis plants need the right controlled environment to succeed. Key factors for indoor cultivations are lights, ventilation, layout, and finding the ideal discreet location.


Choose an available space with direct access to irrigation and electrical outlets. An empty spare room, large closet, basement corner, or cultivation tent securely placed in a garage all make great hidden cultivation room spots.


Cannabis requires powerful light for all vegetative stages. LED grow lights are energy-efficient and come in broad spectrum options simulating natural sunlight. Provide 250-400 watts per square foot for the growth stage and 400-600 watts per square foot for bloom.


Proper airflow and exhaust systems maintain ideal temp, moisture, and fresh CO2 levels. Install low-noise 10-15 cm fans or scrubbers to circulate stale air and reduce smells.


Maximize your space by positioning plants strategically under the lights and allowing room to access and work around them. Set up separate zones for growth, flowering, curing, and propagation.

Growing Substrates

Weed can be cultivated in different substrates, each with pros and cons. Pick a proper option for your specific setup and cultivation style.


The traditional medium, soil is inexpensive and easy for new growers. It provides great taste but requires more irrigation and nutrients to nourish plants. Enrich soil with perlite or coir to improve aeration.

Coco Coir

Made from coir, renewable coco coir holds water but still allows air to the roots. It's more sterile and more consistent than soil. Use coco-specific fertilizers to avoid calcium buildup.

Water systems

In hydro systems, plant roots develop right in nutrient irrigation solution. This enables rapid development but needs close observation of water chemistry. DWC and drip systems are common methods.

Germinating Seeds

Germination prepares your cannabis seeds to begin growing radicles. This prepares them for transplanting into their cultivation medium.

Paper Towel Method

Place seeds between wet paper towels and keep them damp. Inspect after a week for growing taproots indicating sprouting is complete.

Direct Planting

Plant seeds right into wetted growing medium 1⁄4 inch deep. Gently water and wait 7-14 days until seedlings push through the surface.

Cubic rockwool

Soak rockwool cubes Subscribe Now in balanced water. Place seeds 6mm deep into the cubes. Keep cubes moist until seedlings appear within a week to 2 weeks.

Transplanting Young plants

Once germinated, cannabis seedlings need to be transplanted to prevent crowding. Move them into appropriately sized pots.

Ready Containers

Load final pots with growing medium enriched with time-released fertilizer. Allow containers to absorb water for 8-12 hours before repotting.

Carefully Transplanting

Gently separate Contact Us Today seedling roots from germination medium using a spoon. Place into pre-soaked pot at equal depth as before and lightly water in.

Vegetative Stage

The vegetative stage promotes foliage and plant form through 3/4 to full day of continual light exposure. This stage usually lasts 4-8 weeks.

Providing 18-24 Hours of Lighting

Use lamps on a 24 daily schedule or outdoor light to trigger constant growth. Lamp output influences height and internodal spacing.


Use vegetative stage nutrients higher in nitrogen. Make sure pH stays around 5.8-6.3 for full fertilizer uptake. Fertilize 25-50% concentration after 14 days and strengthen slowly.

Training Techniques

Topping, low stress training, and scrogging manipulate growth patterns for flat foliage. This boosts yields.

Bloom Stage

The blooming stage develops buds as plants show their sex under a 12/12 cycle timing. It lasts 8-12 weeks depending on strain.

Changing Light Schedule

Change lamps to 12 hours on, 12 hours off or move outdoors for outdoor 12 hour cycle. This triggers plants to start flowering.


Flushing flushes out fertilizer residuals to enhance taste. Fertilize lightly the first period then just use pH'd water the final 2 weeks.


Continue 12 hour photoperiod but leach using pH-balanced water only. Resume clean watering if buds aren't yet mature after two weeks.


Recognizing when marijuana is fully ripe ensures peak potency and aroma. Harvest plants at peak ripeness.

Signs of readiness

Check swollen calyxes, faded pistils, and 10-15% cloudy trichs. Inspect buds across the plant as they won't all mature evenly.

Cutting Plants

Use sterilized, razor-sharp trimming scissors to carefully cut each plant at the base. Keep several inches of stem attached.


Hang whole plants or colas upside down in a dark room with moderate temperature and RH around 45-65% for 7-14 days.


Aging continues desiccating while improving the buds like fine wine. This process mellows harshness and intensifies terpene and terpene profiles.

Curing containers

Trim dried buds from branches and place into sealed containers, filling about 3⁄4 full. Use a sensor to measure container humidity.

Burping Daily

Unseal jars for a short time daily to gradually reduce humidity. Rehydrate buds if humidity goes under 55%.

Long term storage

After 2-3 weeks when moisture stabilizes around 55-60%, do a final manicure and store forever in sealed jars.


Even experienced cultivators run into various pot plant problems. Identify problems early and fix them properly to keep a strong garden.

Nutrient Deficiencies

Chlorosis often indicate inadequate nitrogen. Purpling stems and leaves signal phosphorus deficiency. Test pH and increase fertilizers gradually.


Spider mites, fungus gnats, mites, and root aphids are frequent weed pests. Use organic sprays, ladybugs, and yellow traps for Contact Us Today natural control.

Powdery mildew

High moisture promotes powdery mildew and root rot. Improve circulation and circulation while reducing RH below 50% during bloom.


With this complete indoor pot cultivation guide, you now have the knowledge to cultivate bountiful potent buds for personal grows. Follow these steps and methods during the germination, vegetative, and flowering stages. Spend in good equipment and carefully monitor your plants. In time, you'll be compensated with sticky aromatic buds you grew yourself under the loving care of your green hands. Good luck cultivating!
