The shortest version: Original Harvest Seeds's take on indica genetics, 18% THC, 9-10 weeks flowering, moderate grow.

Lineage: 80% indica, 20% sativa, tracing back through the original Chemdog family via Original Harvest Seeds. That heritage shows up clearly in the growth pattern — chunky, resinous structure, a 9–10 week flower window, and indoor yields that routinely hit 600 g/m² under dialled-in conditions. The citrus and pine aromas are sharp rather than subtle; expect them to fill a tent well before harvest day, so carbon filtration is worth the investment here.

At 18% THC, the effect leans toward full-body relaxation without being completely sedating — functional enough for early evening, heavy enough that newer users should pace themselves. Difficulty sits at moderate, meaning it rewards basic training techniques like LST or a simple SCROG but won't punish you for small mistakes the way some finicky lines will. It runs well both indoors and out, though outdoor growers in shorter Canadian seasons should start in a greenhouse to protect the finish.

Best suited to intermediate growers who want a proven, high-yielding indica without chasing exotic genetics.

Genetics & Lineage

Chemdog #4 traces its genetics to 80% Indica / 20% Sativa (Original Harvest 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 Original Harvest 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 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Chemdog #4 delivers THC levels of 18%, 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 Chemdog #4

Chemdog #4 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 9-10 weeks with yields of 600g/m2. Plants typically reach 150-220cm 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

Chemdog #4 features a citrus, pine terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. 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, Chemdog #4 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 Chemdog #4?

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.
