From the lab panel — 19% THC, <2% CBD. From grower reports — 500g/m2 yield, fruity/sweet dominant in cured flower. easy grow.

Smell-first: crack a jar of this and the grapefruit hit is immediate — not synthetic candy, actual citrus rind with a sweetness underneath that lingers on the exhale. Sweet Deep Grapefruit is a Coastal Genetics feminized indica that wraps up in 8–9 weeks and regularly pushes 500g/m² indoors when grown under decent light. At 19% THC it's no lightweight, but the effect lands more as a slow, heavy unwind than an immediate knockout — the kind of session that ends on the couch.

The easy difficulty rating isn't marketing padding; this one is genuinely forgiving about environment, running well both indoors and out without demanding obsessive dialing-in. Mold resistance holds up in humid conditions, which takes pressure off late-flower management. If you're newer to growing indicas or just want a reliable fruity strain that doesn't fight you for a good harvest, this fits the bill.

Indoor Growing: Expect a flowering time of 8-9 weeks with yields of 500g/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.

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.

Sweet Deep Grapefruit features a fruity, sweet 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.
