Why Feminized Seeds Are Best for Big Harvests
If you’re serious about yield, feminized cannabis seeds are the clear choice. These seeds are bred to produce only female plants, which means every plant you grow will produce buds—not pollen.
Why This Matters:
No need to identify and remove males
More plants = more canopy coverage
Maximizes space, time, and light use
Simplifies the grow process—ideal for indoor and outdoor setups
With regular seeds, you risk wasting time and resources on males that won’t yield flower. But with feminized seeds, you can plant with confidence, knowing every seed has bud-producing potential.
💡 Pro Tip: Want to keep your harvest fully optimized? Start with strong genetics from our Feminized Seeds Collection.
What Makes a Strain XXL Yield?
Not all cannabis seeds are created equal. Some strains naturally grow larger, produce denser buds, or respond better to training. When shopping for high-yield strains, here’s what to look for:
Key Traits of XXL Strains:
High yield per m²: Usually above 500g/m² indoors, or up to 30 oz/plant outdoors
Fast flowering time: 8–10 weeks is the sweet spot for large harvests
Thick branching: Strong lateral growth supports more bud sites
Resin-rich colas: Denser buds = more weight in your jars
Genetic stability: Reliable structure and performance grow after grow
💡 Pro Tip: XXL yield isn’t just about size—it’s about bud quality, consistency, and harvest timing.
Strains like Godfather OG and Sunset Runtz are perfect examples: compact plants that pump out huge, frosty colas under the right conditions.

Tips to Maximize Your XXL Harvest
Even the best genetics need the right setup to reach their full potential. Here’s how to help your feminized seeds produce the biggest harvest possible:
Use Plant Training
Techniques like LST (Low-Stress Training) and SCROG (Screen of Green) help light reach every bud site. This boosts yield without increasing plant count.
💡 Start training early, especially with strains like Godfather OG or Purple Runtz that respond well to canopy control.
Big buds = high humidity risk. Use oscillating fans and proper ventilation to prevent mold, especially in dense strains like Sunset Runtz.
Feed Smart
Feminized strains growing large will need balanced nutrients during flowering. Use bloom boosters with caution—too much can stress the plant.
Control the Environment
Keep temps between 70–80°F (21–27°C) and humidity between 40–50% in flower. Stable conditions lead to consistent bud growth and resin production.

20 Powerful Strategies to Increase Cannabis Yields
Embarking on a journey of cannabis cultivation and dreaming of a generous increase in your cannabis yields? Whether you’re a novice grower or a seasoned cultivator looking to up your game, we’ve compiled 20 potent strategies to maximize your cannabis harvest. Ready to turn your green thumb into a gold mine? Let’s dive in.
1. Journal Your Journey: Document Your Grow
Keeping a grow journal helps you learn from each grow, refining your methods for future harvests. Track your plants’ progress, note any issues and their solutions, and you’ll be on your way to maximizing your yields.
2. Stay Vigilant: Keep Pests Away
Maintaining a pest-free environment is essential to ensure your plants can grow to their full potential. Implementing preventative pest management practices can keep your plants healthy and ensure all their energy goes towards producing bountiful yields.
3. High-Stress Tactics: Risk for Reward
High-Stress Training (HST) techniques like topping and super cropping can significantly increase cannabis yields when performed correctly. These methods stress the plant in a way that encourages bushier growth with more bud sites.
Mycorrhizal fungi form a symbiotic relationship with plant roots, enhancing nutrient and water uptake. Adding mycorrhizae to your soil can supercharge your plants’ nutrient absorption capabilities, leading to healthier growth and higher yields.
5. Harvest Time: Don’t Rush
Harvesting your plants at the right time is crucial for maximum cannabis yields and potency. Early harvesting can result in smaller, less potent buds. Patience is key – watch your plants closely for signs they are ready to harvest.
6. Feed the Soil: Try Composting
Enriching your soil with organic compost can supply your plants with a smorgasbord of essential nutrients. Composting fosters beneficial microbial life, improving soil structure and fertility. The end result? More robust plant growth and potentially increased yields.
7. Proper Pot: Choose the Right Type
The type of pot you choose can significantly impact your plant’s health. Fabric pots, for example, offer excellent aeration and drainage, promoting healthier root systems and leading to sturdier plants with the potential for higher yields.
8. Side Lights: Illuminate Lower Branches
While top lighting is standard in most grow rooms, side lighting can provide valuable supplemental illumination. Lower branches often get less light, reducing their productivity. Side lighting can help to even out growth, promoting a balanced canopy and increased cannabis yields.
9. Bottoms Up: Try Underwatering
Underwatering — giving water less frequently but in greater amounts — can stimulate root growth. The longer dry periods encourage roots to stretch out in search of moisture, leading to stronger root systems and more resilient, productive plants.
10. Measure Up: Keep an Eye on PPM
Maintaining the right PPM (parts per million) is crucial to ensure your plants are getting the right amount of nutrients. Overfeeding can lead to nutrient burn, while underfeeding might result in deficiencies. Regularly check your nutrient solution’s PPM to keep it in the sweet spot.
11. pH Perfect: Monitor pH Levels
The pH level of your grow medium significantly affects nutrient uptake. If pH levels veer off the optimal range, your plants might suffer from a nutrient lockout, hampering their growth. Regular monitoring and adjustment of pH can ensure healthy growth and abundant yields.
12. Prune for Power: Try Defoliation
Defoliation, or strategic leaf removal, can improve light penetration to lower branches, increasing overall cannabis yields. By removing large fan leaves that block light, you allow more energy to be directed toward bud production. But tread carefully, overdoing it may stress your plants.
13. Soil-less Success: Try Hydroponics
Hydroponic systems, which grow plants without soil, can offer faster growth rates and larger yields than traditional soil methods. By delivering nutrients directly to the roots, your plants can focus more energy on growing above the surface, resulting in a bigger, better harvest.
14. The Sweet Effect: Use Molasses
Molasses is a natural supplement that can enhance soil health and boost beneficial microbial activity. These microorganisms can help break down nutrients, making them more accessible to your plants. This leads to healthier plants and can potentially increase cannabis yields.
15. More Room: Use Larger Containers
Bigger pots can lead to bigger plants. A larger container allows your cannabis plant’s roots to stretch out and grow robustly, leading to healthier, heftier plants. Experiment with pot sizes to give your plants the space they need to reach their yield potential.
16. Climate King: Control Your Growing Environment
Creating an ideal growing environment is key to successful cannabis cultivation. Optimal temperature, humidity, and ventilation encourage healthier growth and ward off pests and diseases. Equip your grow space with reliable climate control systems to ensure your plants flourish.
17. Nutritional Balance: Provide the Correct Amount of Nutrients
Providing the right balance of nutrients is crucial for robust plant growth. Too much or too little of any nutrient can cause problems like a nutrient burn or deficiency. Tailoring a nutrient schedule for your cannabis plants can help them reach their full yield potential.
18. Steer Your Green: Manipulate Your Plants’ Growth
Strategic plant manipulation techniques such as Low-Stress Training (LST) and High-Stress Training (HST) can influence how your plants grow. Directing your plants to grow horizontally can expose more nodes to light, encouraging extra bud production and potentially increasing yields.
19. Enhance Photosynthesis: Supplement with CO2
Plants require carbon dioxide (CO2) for photosynthesis, the process that turns light into energy. In indoor settings, supplementing your grow room with CO2 can enhance this process, supporting healthier plant growth and amplifying bud production.
20. Brighten Up: Increase Light Intensity
Your cannabis plants thrive on light. Increasing light intensity in your grow space fuels photosynthesis, promoting faster, more vigorous growth. Implement high-quality LED or HPS lights to shower your plants with sufficient luminance, resulting in denser buds and higher yields.
Maximizing cannabis yields is both an art and a science, sharpened through practice and perseverance.
