Runt-Zu

This creation by Grateful Seeds combines the legendary Runtz with the extremely sour and at the same time extremely tasty Lemon Shocker. Runt-Zu is a medium-sized plant that is not difficult to grow, it is a mixture of Indica and Sativa for indoor cultivation, but it also thrives well outdoors in areas that are not too cold.

Runt-Zu is characterised by its strong aroma and truly impressive scents - it offers aromas and flavours dominated by fruity citrus notes. These notes are further enriched with tart flavours reminiscent of chemicals, as well as creamy and sweet treats.

• Lineage: Runtz x Lemon Shocker
• Genetics: Indica / Sativa
• Flowering Time: 9 weeks
• Smell: fruity citrus notes, sour, chemicals, creamy, sweet, sweets
• THC: 22%

• Grateful Seeds: Breeding with Care and Character

Grateful Seeds is a collective that grew out of a real love for the cannabis plant. They are based in Barcelona, but their work connects across places like the USA, Morocco, Mexico, Switzerland, and Spain. Over the years they have built their name by creating breeding lines that growers remember for a few things: heavy resin production, uncommon cannabinoid mixes, and terpene profiles you do not come across every day. Each strain they release feels like it carries its own character, something made with time and patience.
