The shortest version: Blimburn Seeds's take on indica genetics, 20-25% THC, 8-9 weeks flowering, moderate grow.

Blimburn Seeds lists this at $25.98 — below the median of $29.76 across 19 listings. Pack options: 3-seed at $25.98, 5-seed at $36.20, plus larger sizes.

Smell-first, this one gives itself away before the jar is even open — ripe citrus and skunky fruit in a combination that leans sweeter than most indica-leaning lines but never loses that earthy bite. Rainbow from Blimburn Seeds finishes in 8–9 weeks and has posted 600–800g/m² in controlled indoor runs, which is a legitimate number for a feminized indica at moderate difficulty. THC sits in the 20–25% range, so the effect is substantial but not the kind that pins first-time users to the couch indefinitely.

It handles both indoor and outdoor environments without demanding a lot of intervention, which makes it a reasonable step-up for growers who've done a few successful runs and want heavier yields without chasing a temperamental cultivar. The fruity-skunk profile also makes it a solid candidate if you're building a diverse harvest — it contrasts well alongside more diesel-forward or floral strains in a mixed room.

Best suited to intermediate growers ready to push canopy management for those upper-end yield numbers.

Genetics & Lineage

Rainbow traces its genetics to Rainbow (Blimburn Seeds). This indica-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Blimburn Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Rainbow delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Rainbow

Rainbow is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 600-800g/m2. Plants typically reach 100-180cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Rainbow features a fruity, citrus, skunky, earthy terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Rainbow is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow Rainbow?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
