    Top 15 Highest Yielding Strains

    1. Bubba Kush fem - 600 to 1500 gr/m2

    Bubba Kush's stocky structure and giant buds are legendary.

    A favorite since the 1990s, you can expect anywhere between 600 - 1500 grams per m2, depending on your setup.


    Bubba Kush is an easy-to-control and grow strain despite its impressive big yield.

    If you’re a beginner wanting the most bang for your buck, this is a fine option. To return the highest yields, you'll have to adopt more advanced growing techniques to manipulate growth and coax larger buds.

    These largest yields of up to 1500 grams per m2 occur with outdoor or greenhouse growth. For this, you’ll need a warm and dry climate, although Bubba Kush is somewhat forgivable with short cold spells.

    Even if you can’t grow outdoors, the indoor yields are impressive. Just be sure to prune between the bushy branches to allow light to reach the central buds.

    Smell, taste, and effects

    Bubba Kush has a unique aroma of petrol and earth courtesy of its extraordinary THC levels.

    This flavor gives over to notes of coffee, cinnamon, citrus, and sweet chocolate. Bubba Kush offers dreamy and euphoric effects that blanket the mind.

    It’s particularly suited for treating insomnia, stress, and depression.

    2. Super Silver Haze - 600 to 1500 gr/m2

    Award-winning Super Silver Haze boasts an impressive yield potential of 600 - 1500 grams per m2.

    Once one of Amsterdam's best-kept secrets, it's now getting the worldwide acclaim it deserves as one of the highest-yielding strains ever.


    Super Silver Haze has an excellent growing profile, but it's best for experienced hands. That's because you'll have to keep an eye on the diet and soil at each stage of the plant's life.

    With this care comes a very generous yield of exceptional quality, reaching a potential of 1500 grams per m2. These big-growing heights can be easily attained outdoors in Mediterranean-like conditions.

    If your climate is too humid, cold, or overcast, you can bring your planting indoors. Here, Super Silver Haze responds exceptionally to hydroponics and SCROG training methods. Indoors, you can get impressive yields of 800 grams per m2.

    Sexxpot's solid Indica profile makes it easy to grow and care for.

    With high mold and pest resistance, it's suited for all skill levels. While bigger yields of 1200 grams per m2 are potential outdoors, you have to keep an eye on humidity levels.

    Although warm and sunny conditions provide the best outdoor growth potential, Sexxpot copes well with cooler spells too. Many choose to grow Sexxpot indoors, where you can successfully apply different training methods. Indoors the yields are somewhat smaller, at 1000 grams per m2, but still very impressive.

    Smell, taste and effect

    While easier to grow than Jack Herer, Jack Widow still benefits from experienced hands.

    It has some sensitivity to humidity, mold, and pests, and is not happy with nutritional or soil mistakes. Still, with good care and the use of SOG or SCROG techniques indoors, you can expect an incredible 650 grams per m2. Outdoor growing is more difficult but beneficial for large yields.
