❓ THC Flower FAQ

Permanent Marker is our most popular and highest-volume strain with 253+ verified UK reviews and a 4.70★ average rating. It is an indica-dominant hybrid testing at 25–35% THC with a fuel-floral-candy terpene profile and very long-lasting effects. Atomic Apple is our second most-rated at 4.83★ from 250+ reviews and is the top choice for anyone who prefers sativa-leaning daytime effects.

For beginners we recommend starting with strains in the 18–22% THC range — Mango Haze, Amnesia Haze, Strawberry Cough, White Widow or Blue Cheese are all good entry points. These deliver genuine cannabis effects at a manageable intensity. Avoid anything above 24% THC until you have established your tolerance over multiple sessions. Do not start with Permanent Marker, Alpine Sunrise or Cherry Marker — these are experienced-user strains only.

Yes. Every strain at Leaflybuds is independently lab-tested with a Certificate of Analysis (COA) confirming THC percentage and the absence of pesticides, plant growth regulators (PGRs), solvents and heavy metals. PGRs are growth chemicals sometimes used in low-quality UK cannabis that produce harsh-tasting, chemically-flavoured bud with degraded effects. None of our flower contains PGRs, artificial additives or cutting agents of any kind.

Most strains are available in 3.5g, 7g, 14g, 28g options. The minimum order across the entire Leaflybuds site is £150. Flower pricing starts from £60 for 3.5g on entry-level strains and goes up to £85 for 3.5g on premium Cali genetics. Larger quantities give significantly better value per gram — the 28g price works out to roughly 40–50% cheaper per gram than the 3.5g price on most strains.

All Leaflybuds flower orders are vacuum-sealed in odour-proof mylar bags and packed inside a plain brown or white postal box with no external branding, no product names visible and no indication of contents. The sender address is a neutral business address. Royal Mail 24 Tracked is used for all deliveries with a tracking number emailed as soon as your order leaves our London or Manchester dispatch hub.
