Our take
Rainbow Glue is a feminized, indica-dominant cross of Zkittlez and Gorilla Glue #4, bred by BSB Genetics. At 22% THC, it sits firmly in the high-potency range while remaining one of the more forgiving strains for first-time growers. Expect a layered aroma — sweet and sour up front, grounded by earthy pine — and buds that lean toward the denser side of medium-to-large.

Growing notes
Rainbow Glue is rated beginner-friendly and adapts well indoors or out. Outdoors, it suits sunny, continental, and Mediterranean climates, finishing by September. Indoors, the roughly 53-day flower period keeps your total cycle tight. Plants reach a medium height, making them manageable in tents or limited outdoor space. Dense bud structure means good airflow during late flower will help prevent moisture buildup.
