What are high yield seeds?

Every cannabis grower's dream is to have a garden full of high-yielding strains. Many factors influence how big a harvest your crops produce. Due to improved cultivation techniques, gardeners can maximize their growing space. One plant has the potential to develop a lot more buds. How can you do this? Growers cross the genetics of various cultivars to create perfect seeds that provide the most yields.


High yield cannabis seeds are for sale across the USA. Getting your favorite seeds from other growers or a dispensary around the corner is quick and convenient, but are they viable? Will they germinate and develop well? Secure your autoflower, feminized, or regular heavy yield seeds from our reputable seed bank. With e-commerce growing as fast as autoflowers, cultivators now benefit from shopping for their favorite seeds online.


Here at i49 Genetics, we've simplified the process of getting your cannabis seeds. Filter your search for these types of seeds to display all available options. Each cultivar comes with descriptive details about its growth characteristics, effects, flavors and aromas, and other helpful information. We offer excellent cultivating support and hold to that germination guarantee.


Why grow high-yielding seeds?


Cultivating high yield cannabis seeds saves you time and money in the long run. Instead of utilizing a large area to grow many crops to harvest tons of buds, optimize small areas with high-yielding plants. Having a few plants per square foot reduces the number of crops you attend to at a time. The bud production on five individual plants is achievable on one or two heavy-yielding ones.


Choosing to cultivate high-yield marijuana seeds is especially useful to those who don't have much space but still desire plenty of buds. It's cost-effective for an indoor grow setup. You won't need as much equipment to cover a large area with fewer plants.


Discover why you should choose marijuana seeds to get the highest yields below.


High yield weed seeds to grow outdoors


If you’re planning to grow your crops in the open, get high yield outdoor seeds. The plants grown from these seeds adapt well to external environments. They’re tough enough to deal with changing weather conditions and still produce high yields.


Autoflowering cannabis plants generally provide smaller harvests. With heavy yield autoflower seeds, your crops deliver significantly more buds. Place your autos in a spot that receives direct sunlight to maximize yields further.


Feminized cannabis seeds are photoperiod variants. To begin flowering, their light cycle must change from 18/6 (18 hours of light/6 hours of dark) to 12/12. Outdoors, the natural light from the sun triggers the switch. Keep your feminized crops in the vegetative stage for longer to increase yield production.


Why sow your cannabis seeds outdoors? Cannabis plants harvested from regular and feminized generally produce more buds outside compared to indoor cultivation methods. It saves you time and money as Mother Nature takes care of most of the nurturing.


Our selection of high yield outdoor seeds includes the following.

How to grow high yield seeds: Is it easy?

These strains make for a cannabis gardening journey with significant rewards. Thanks to modern-day cultivation methods, growers have taken much-loved strains and improved their development abilities. Autoflower seeds are especially favored because you enjoy less work, faster-growing, and super generous harvests.


Grow your high-yield seeds with the following tips to achieve the best results.




Before you get started growing, your first step is germination. Our favored technique is the paper towel method. 


You'll need: 


  • Two non-porous paper towels
  • Two dinner plates
  • Room temperature purified water
  • Your high-yield marijuana seeds
  • Tweezers


Once you've gathered the tools, follow these instructions:


  • Wet your paper towels with purified water. Wring out any excess, so they're damp and not soaked.
  • Place one towel onto one of the dinner plates and use the tweezers to spread your seeds over the towel.
  • Cover the seeds with the other paper towel and gently sprinkle some water over the top. Remember, the environment must never be drenched, only moistened.
  • Lift the paper towels from the surface of the plate to ensure there isn't additional water lying beneath.
  • Close the seeds inside with the second plate to create a warm, dark environment. Put this setup inside a cupboard or drawer that doesn't receive direct light.
  • The germination process takes 24–120 hours to complete. Regularly check your seeds during this time. The towels should never dry out.
  • Once your high yield cannabis seeds present their taproots, they're ready to move to your growing medium of choice.


What kind of nutrients do they need?


Cannabis plants thrive on macronutrients like nitrogen (N), phosphorus (P), and potassium (K). They also need micro nutes like calcium, iron, copper, and zinc. Marijuana crops need different nutrient feeds at each stage of growth. In their vegetative phase, they need a lot more nitrogen to enhance the development of leaves and stems. During flowering, crops produced from heavy yield seeds need more phosphorus and potassium.


The primary nutes N–P–K ratio is displayed on nutrient packaging as 4:2:3. It indicates how much of each compound is available in the product.


What kind of water is best for high yields?


Distilled water (soft water) is best for your marijuana crops since it's free of salts or heavy metals that usually hinder nutrient absorption. Using purified H2O eliminates the presence of bacteria that causes contamination to the roots. Ensure the water for your crops growing from high yield marijuana seeds is tepid at a temperature of 68℉. The quality of H2O is greatly affected by the pH balance. If it's too acidic or alkaline, it negatively impacts the growth of your crops.


  • Acidic water: 0–4.9
  • Alkaline water: 7.0–14
  • Balanced pH: 5.0–7.0


A couple of words about growing high yield marijuana seeds


Sufficient airflow is vital for crops growing from high yield seeds if you're cultivating indoors. Keep relative humidity regulated at all times. Autoflowers need a milder humid environment during flowering than throughout the seedling and early vegging stages.


Cultivating seeds indoors requires quality lighting, especially if they're regular or feminized photoperiod variants. Although autoflowers don't depend on light exposure to switch to flowering, they still need warmth to grow.


High-intensity lights like metal-halide lamps are ideal if you don't mind spending extra pennies on electricity bills. LED lights are an excellent alternative for milder heat generation and lower costs. 


For indoor setups, an 18/6 light provision is beneficial in encouraging robust growth and increased bud production. Mother Nature takes care of the lighting outdoors. 


Plant your seeds directly into large pots to encourage healthy root development and growth patterns. To increase results, use 15–20 liter pots. 


If you choose to raise your crops produced from high-yield cannabis seeds outdoors, protect them from the elements of nature, including pests.


For your autoflower seeds with high yield production, use a light growing medium. Autos grow fast and vigorously, and airy soil makes it easy for them to develop a healthy root system. The ideal pH for soil-based growing is 6.5.


Add a root stimulant to enhance development further. Ensure you have sufficient support for those heavy budding colas on the crops grown from this type of seeds. Adding side structures like bamboo sticks or trellis netting helps the plants carry heavy loads.


Choose your water carefully. If the H2O is unsafe for human consumption, it's hazardous for your crops. Reverse osmosis water is ideal as it doesn't contain all the impurities usually found in what comes out of a tap.


Crops produced from heavy-yield autoflower seeds don't need as many nutrients as photoperiods. Lightly fertilized soil is sufficient for autos.


Marijuana plants need more nitrogen during vegging to promote growth and more phosphorus and potassium during flowering for bud production.


With high yields come more foliage. Train your crops to encourage lateral growth. Low-stress training (LST) techniques allow you to do this without stressing the plants. Once more bud sites receive additional light, it encourages the development of higher yields.


Sometimes you notice ripened buds at the top of your crops produced from high yield cannabis seeds. Flowers usually mature faster at the top than they do further down on the plants. Harvest the ready ones, and wait another 1–2 weeks before clipping the others.
