Tall Cannabis Plant Seeds

Tall cannabis plant seeds are made for growers who want to go big—towering sativas that stretch toward the sky and deliver massive, energizing harvests. These are the plants that dominate gardens, producing huge colas, rich aromas, and soaring highs.

What Are Tall Cannabis Plant Seeds?

Tall strains are mostly sativa-dominant plants known for their height, long internodes, and extended flowering times. Outdoors, they can reach 8–12 feet or more, while indoors, they still require space, training, and strong light.

Unlike compact indicas, tall cannabis strains thrive in open environments, producing pound-level harvests rather than single ounces. Classics like Amnesia Haze, Jack Herer, and Super Silver Haze are iconic for their height, vigor, and clear-headed effects. For growers in hot, sunny regions, our sunny climate seeds are also excellent choices.

What Makes Tall Strains Unique?

Tall strains stand out for their scale, structure, and strength. Outdoors, they resemble trees—broad canopies, thick stems, and spear-like buds. They grow upward fast, rewarding patient growers with massive yields and powerful highs.

Growers love:

• Amnesia Haze: A citrus-spiced classic that thrives in heat and sun.
• Jack Herer: Fast-growing and uplifting, perfect for outdoor height.
• Super Silver Haze: Tall, resinous, and legendary among long-time growers.
• Bruce Banner: Hybrid power and sky-high potency with vigorous vertical growth.
• Sour Diesel: A tall, fast-finishing fuel-forward favorite.

These genetics are perfect for growers who have space to stretch and the patience to let plants fully mature. For those seeking a balance between height and yield speed, explore our high-yield seeds.
