Whether you're beginning pot production or looking to improve your existing harvest, following this complete guide will help you produce big, high-quality yields right at home. With the right gear, methods, and care, cultivating marijuana indoors can be an extremely satisfying and cost-effective endeavor.
Choosing Weed Strains
The first step in planning your indoor harvest is choosing the right marijuana varieties to cultivate. The three main types of pot plants each have their own qualities.
Sativas
Known for their energizing cerebral effects, these strains grow tall and slender with narrow leaves. They thrive in tropical tropical 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
Indicas provide relaxing body-focused effects and grow short and bushy with broad leaves. Accustomed to cooler mountain climates, they flower faster within 2-2.25 months. Popular indica strains include Northern Lights, Bubba Kush, and Bubba Kush.
Hybrids
Hybrid varieties mix traits from both sativas and relaxing strains. They offer blended effects and have medium flowering times around 9-10 weeks. Well-known mixes are OG Kush, Girl Scout Cookies, and Blue Dream.
Setting Up Your Cultivation Space
Weed plants need the right controlled environment to succeed. Key factors for indoor grows are lights, ventilation, layout, and finding the ideal discreet spot.
Location
Choose an unused space with quick access to irrigation and electrical outlets. An empty extra bedroom, unused closet, basement corner, or cultivation tent tucked away in a garage all make great stealthy grow room spots.
Lights
Weed requires strong light for all growth stages. LED grow lights are efficient and come in full spectrum options simulating real sunlight. Provide 250-400 watts per square foot for the growth stage and 20-40 watts per square foot for bloom.
Ventilation
Proper airflow and exhaust systems keep ideal temp, moisture, and pure CO2 levels. Install silent 10-15 cm fans or scrubbers to circulate stale air and eliminate smells.
Layout
Maximize your space by arranging plants carefully under the lamps and leaving room to access and work around them. Set up distinct zones for growth, flowering, curing, and propagation.
Growing Mediums
Pot can be grown in different mediums, each with pros and cons. Pick a proper option for your particular setup and cultivation style.
Soil
The traditional substrate, soil is inexpensive and simple for beginners. It provides great flavor but requires more watering and nutrients to feed plants. Enrich soil with vermiculite or coir to enhance aeration.
Coconut coir
Made from coir, renewable coco coir retains water but still allows air to the roots. It's cleaner and more predictable than soil. Use coco-specific nutrients to prevent accumulation.
Water systems
In water systems, plant roots develop right in nutrient water solution. This allows rapid growth but needs close monitoring of water chemistry. Deep water culture and drip systems are common techniques.
Germinating Seeds
Germination activates your weed seeds to begin sprouting taproots. This prepares them for planting into their growing medium.
Paper Towel Method
Put seeds between wet paper towel and maintain them damp. Inspect after a week for emerging taproots indicating germination is complete.
Direct Planting
Plant seeds right into wetted cultivation medium 6mm deep. Gently water and wait 7-14 days until seedlings break through the top.
Rockwool Cubes
Presoak rockwool cubes in balanced water. Place seeds 6mm deep into the cubes. Keep cubes wet until seedlings emerge within 1-14 days.
Transplanting Young plants
Once germinated, marijuana young plants need to be transplanted to avoid overcrowding. Move them into proper sized pots.
Ready Containers
Fill final containers with cultivation medium enriched with time-released fertilizer. Allow containers to soak up water for 8-12 hours before repotting.
Carefully Transplanting
Gently loosen young roots from sprouting medium using a spoon. Place Request More Info into pre-soaked pot at same depth as before and lightly water in.
Vegetative Stage
The growth stage encourages leafy growth and plant structure through 3/4 to full day of continual light exposure. This stage usually lasts 1-2 months.
Providing 3/4 to full day of Light
Use grow lights on a 24 daily cycle or natural sunlight to initiate nonstop photosynthesis. Light output influences height and internodal spacing.
Nutrients
Use grow stage nutrients higher in N. Make sure pH stays around 6.5 for full nutrient absorption. Fertilize 25-50% strength after 14 days and strengthen gradually.
LST and topping
Fimming, LST, and scrogging direct growth patterns for flat canopies. This boosts yields.
Flowering Stage
The blooming stage develops buds as plants reveal their sex under a 12/12 light timing. It lasts 8-12 weeks based on strain.
Switching to 12/12
Switch lamps to 12 hours on, 12 hours off or place outside for natural 12 hour cycle. This signals plants to begin flowering.
Stop Fertilizing
Leaching flushes out nutrient salts to enhance taste. Fertilize lightly the first weeks then just use pH'd water the last 2 weeks.
Flushing
Continue 12 hour photoperiod but flush using neutral pH water only. Return to plain watering if buds aren't yet mature after two weeks.
Harvesting
Recognizing when weed is completely mature ensures maximum potency and aroma. Harvest plants at peak ripeness.
Identifying Ripeness
Check swollen calyxes, faded pistils, and 5-15% cloudy trichs. Check buds around the plant as they don't all mature evenly.
Harvesting plants
Use clean, sharp trimming scissors to carefully cut each plant at the base. Keep 5-10cm of stem attached.
Curing
Suspend whole plants or colas upside down in a dark room with moderate temperature and RH around 45-65% for 1-2 weeks.
Curing
Curing continues desiccating while aging the buds like fine wine. This technique mellows harshness and further develops terpene and terpene profiles.
Jars and Humidity
Manicure cured buds from stems and store into glass jars, packing about 75% capacity. Use a hygrometer to monitor container moisture.
Burping Daily
Open containers for a short time daily to slowly lower moisture. Rehydrate buds if humidity drops below 55%.
Long term storage
After 14-21 days when moisture stabilizes around 55-65%, perform a last manicure and keep long-term in sealed jars.
Troubleshooting
Even seasoned growers run into various weed plant problems. Detect problems soon and fix them properly to maintain a strong garden.
Poor feeding
Chlorosis often signify insufficient nitrogen. Purpling stems and leaves show low phosphorus. Test pH and boost fertilizers slowly.
Pests
Spider mites, fungus gnats, thrips, and root aphids are frequent pot pests. Use organic sprays, ladybugs, and sticky traps for natural control.
Mold
High humidity promotes botrytis and root rot. Increase circulation and venting while reducing RH under 50% during bloom.
Summary
With this complete indoor pot growing guide, you now have the info to grow plentiful potent buds for private grows. Apply these techniques and techniques throughout the seed starting, growth, and bloom stages. Spend in quality 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!
