Weed Grow Instructions

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

Choosing Weed Varieties

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

Energizing strains

Known for their invigorating intellectual effects, these strains spread tall and slender with narrow leaves. They flourish in tropical tropical climates and have a longer blooming time between 10-12 weeks indoors. Top sativa strains include Sour Diesel, Durban Poison, and Jack Herer.


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


Hybrid strains blend traits from both sativas and relaxing strains. They offer combined effects and have moderate flowering times around 2.25-2.5 months. Popular mixes are Blue Dream, OG Kush, and Blue Dream.

Setting Up Your Cultivation Space

Marijuana plants need the right controlled environment to thrive. Key factors for indoor grows are lighting, airflow, layout, and finding the ideal discreet area.


Choose an empty space with quick access to water and electrical outlets. An empty extra bedroom, unused closet, corner of the basement, or cultivation tent tucked away in a garage all make great hidden grow room spots.


Pot requires powerful light for all vegetative stages. LED grow lights are energy-efficient and come in broad spectrum options simulating natural sunlight. Provide 15-25 watts per square foot for the growth stage and 400-600 watts per square foot for flowering.


Proper ventilation and exhaust systems maintain ideal temp, moisture, and fresh CO2 levels. Set up low-noise 4-6 inch blowers or scrubbers to refresh old air and reduce odors.


Optimize your space by arranging plants strategically under the lamps and leaving room to reach and work around them. Set up distinct zones for growth, flowering, curing, and cloning.

Cultivation Mediums

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


The classic medium, soil is affordable and simple for new growers. It provides great taste but requires more irrigation and fertilizing to feed plants. Amend soil with perlite or coir to improve aeration.

Coco Coir

Made from coconut husks, renewable coco coir retains water but still lets in air to the roots. It's cleaner and more consistent than soil. Use coir-specific nutrients to prevent accumulation.


In water systems, plant roots develop directly in fertilizer water solution. This enables quick growth but needs careful observation of water properties. 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 Click Here them damp. Check after 2-7 days for growing radicles indicating germination is complete.

Planting directly

Insert seeds directly into pre-moistened cultivation medium 6mm deep. Gently water and wait 1-2 weeks until sprouts break through the top.

Cubic rockwool

Presoak rockwool cubes in pH-adjusted water. Place seeds 1⁄4 inch deep into the cubes. Keep cubes wet until sprouts appear within 1-14 days.

Transplanting Young plants

Once germinated, pot Discover More seedlings need to be transplanted to prevent crowding. Move them into proper sized containers.

Preparing Containers

Load large containers with growing medium amended with slow-release nutrients. Let pots to soak up water overnight before repotting.

Gently repotting

Carefully separate seedling roots from germination medium using a spoon. Put into pre-soaked pot at equal depth as before and lightly water in.

Vegetative Stage

The vegetative stage promotes leafy growth and plant form through 3/4 to full day of continual lighting intensity. This stage usually lasts 1-2 months.

Using 18-24 Hours of Light

Use lamps on a 24 daily schedule or outdoor light to initiate constant photosynthesis. Light intensity influences size and internodal spacing.


Use vegetative stage nutrients higher in nitrogen. Make sure pH remains 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 even canopies. This increases yields.

Flowering Stage

The blooming stage grows buds as plants reveal their sex under a 12/12 light timing. It lasts 2-3 months based on strain.

Changing Light Schedule

Switch lamps to 12/12 or move outdoors for outdoor 12/12 timing. This triggers plants to begin flowering.

Stop Fertilizing

Leaching flushes out nutrient salts to improve flavor. Feed lightly the first weeks then just use plain water the last 2 weeks.


Maintain 12/12 light timing but flush using neutral pH water only. Return to plain watering if buds aren't ripe after two weeks.


Knowing when pot is completely mature ensures maximum potency and aroma. Cut down plants at optimal maturity.

Signs of readiness

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

Cutting Plants

Use sterilized, razor-sharp pruning shears to carefully slice each plant at the base. Leave 5-10cm of stalk attached.


Suspend whole plants or branches inverted in a dark room with moderate temp and humidity around 45-65% for 7-14 days.


Aging keeps drying while improving the buds like fine wine. This technique mellows harshness and intensifies cannabinoid and terpene profiles.

Curing containers

Trim cured buds from stems and store into glass jars, filling about 75% capacity. Use a hygrometer to monitor jar moisture.

Burping Daily

Unseal Donate Here containers for a few hours each day to slowly reduce moisture. Remoisten buds if RH drops below 55%.

Long term storage

After 2-3 weeks when moisture stabilizes around 55-60%, perform a last trim and keep long-term in airtight jars.

Common Problems and Solutions

Even experienced cultivators run into various marijuana plant problems. Identify problems early and fix them properly to maintain a healthy garden.

Nutrient Deficiencies

Chlorosis often indicate inadequate nitrogen. Purpling stems and leaves signal low phosphorus. Check pH and boost fertilizers gradually.


Spider mites, fungus gnats, mites, and root aphids are frequent cannabis pests. Use organic sprays, ladybugs, and sticky traps for organic control.


Excessive humidity promotes botrytis and bud rot. Increase airflow and venting while reducing humidity under 50% during flowering.


With this complete indoor cannabis cultivation guide, you now have the info to cultivate plentiful strong buds for private grows. Follow these steps and techniques during the germination, growth, and flowering stages. Invest in quality gear and closely check on your plants. In time, you'll be rewarded with frosty aromatic buds you raised yourself under the patient guidance of your green hands. Happy growing
