Our take
Rainbow Runtz Autoflower is a Zkittlez × Do-Si-Dos cross that leans indica and tests around 25% THC — strong by any measure. The flavor profile runs floral, berry, and candy, backed by limonene, caryophyllene, and myrcene. It's a good fit for growers with a few grows under their belt who want heavy, resinous harvests without a long wait.

Growing notes
Rated intermediate, so Rainbow Runtz rewards growers who can manage their environment consistently. It performs well both indoors and outdoors, finishing its full cycle in roughly 70 days inside. Outdoor growers in most US climates can expect harvest by mid-October. Plants reach a medium height, making them manageable in tents or garden beds. Dialing in humidity during late flower helps protect those dense buds.
