Welcome to IRS Seeds

At IRSseeds.com, our mission is to offer top-quality cannabis seeds to cultivators and enthusiasts.

Indica, Ruderalis & Sativa

Each type has unique characteristics and benefits, so you can find the perfect strain to meet your needs.

Begin your cultivation journey with us today and explore the full potential of cannabis.

  • Characteristics: Indica plants are typically short and bushy with wide, broad leaves. They are known for their high resin production and dense, sticky buds.

  • Sowing: Indica seeds thrive in cooler climates. Plant them in well-drained soil with plenty of organic matter.

  • Caring: These plants require regular watering, especially during the vegetative stage. They are more resistant to cold temperatures.

  • Harvesting: Indica plants have a shorter flowering period, usually 6-8 weeks. Harvest when the trichomes are milky white.

  • Enjoying: Indica strains are known for their relaxing and sedative effects, making them ideal for evening use.

  • Characteristics: Ruderalis plants are small and hardy. They are known for their auto-flowering trait, meaning they flower based on age rather than light cycles. They have lower THC and higher CBD content.

  • Sowing: Ruderalis seeds can be planted in various climates, including harsh environments. Due to their small size, they are ideal for indoor growing.

  • Caring: These plants are resilient and require minimal care. Ensure they have adequate light and nutrients.

  • Harvesting: Ruderalis plants have a rapid growth cycle, often completed in 8-10 weeks. Harvest when the trichomes are cloudy.


  • Enjoying: Due to their higher CBD content, Ruderalis strains are often used for medicinal purposes, providing relief without strong psychoactive effects.

  • Characteristics: Sativa plants are tall and slender with narrow, finger-like leaves. They are known for their uplifting and energetic effects.

  • Sowing: Sativa seeds prefer warmer, tropical climates. Plant them in well-drained soil with good sunlight exposure.

  • Caring: These plants need plenty of light and regular watering. They are more sensitive to cold temperatures.

  • Harvesting: Sativa plants have a longer flowering period, often 10-16 weeks. Harvest when the trichomes are amber.

  • Enjoying: Sativa strains are ideal for daytime use, providing an energetic and cerebral high.
