hybrid
Rainbow Blast
aka RNB
The Rainbow Blast strain is an indica-dominant hybrid that crosses Zkittlez with Rainbow Chip, pulling fruity depth from one parent and layered complexity from the other. Sometimes listed as RNB and occasionally confused with Rainbow Burst, this strain has been showing up across California's recreational market and New York's medical dispensaries through growers like Curaleaf. The aroma opens with ripe berry and grape notes backed by bright citrus, while an earthy, herbal undertone keeps it grounded. On the inhale, those fruity flavors come through clearly, with a tropical edge that rounds out the profile without overwhelming it.
Consumers who've tried Rainbow Blast frequently describe an initial wave of euphoria and giggly sociability that may settle into a heavier, sleepier quality over time. Many reviewers note that the experience deepens gradually, making this one a strong pick for evening sessions or winding down after a long day. Fans of the strain also report increased appetite, so it's worth keeping that in mind if you don’t have snacks prepared. Visually, the buds are dense and compact with heavy resin coverage, reflecting that indica-leaning structure you'd expect from its Zkittlez lineage.
Rainbow Blast is a moderate-difficulty strain that stays compact at 3–4 feet indoors, making it a solid pick for growers working with limited canopy space. Outdoors, it stretches to 4–5 feet with a bushy, indica-leaning structure that fills out nicely in warm, Mediterranean-style climates where temperatures hover between 68–80 degrees Fahrenheit. Flowering wraps up in roughly eight to nine weeks, and growers often report yields around 350–450 g/m² indoors or 14–18 oz/plant outdoors when conditions cooperate. You'll want to keep humidity dialed in around 40–50% during flowering to protect those dense, resinous buds from mold. It's not the most demanding strain out there, but some experience with nutrient sensitivity goes a long way toward getting the best results.
