Seb's take
Chemdawg and Girl Scout Cookies, selected phenotypes reunited for a heavier hit at up to 30% THC. Sweet spice softens the garlic-diesel base on the nose; the high is grounding yet clear-headed, easing the body while keeping the mind engaged, relaxed and euphoric throughout.
Where it comes from
Chemdawg and Girl Scout Cookies, selected phenotypes reunited by Barney's Farm through advanced breeding for a heavier hit than the standard cross. The record puts her at 90 per cent indica and credits her structure directly to the lineage: dense buds, heavy trichomes, deep colour across the calyxes. Chemdawg brings the pungency, Girl Scout Cookies the sweetness, and the selection work sharpens both. A considered heavyweight, not a happy accident.
Nose & flavour
The record calls it a genetic duality, and the phrase fits: sharp garlic tones set against a subtle sweetness, with a diesel weight and a spiced edge filling out the middle. It is the classic GMO signature, savoury and pungent, the sweetness keeping the garlic honest rather than overwhelming. An aroma that lingers, the record notes, long after each draw.
The high
Grounding yet clear-headed, as the record has it, a steady relaxation that eases the body while keeping the mind engaged. Uplifting and euphoric run through it, so despite the heavy indica build it is more attentive than sedentary. A high that settles you without switching you off. Given the potency on offer, meet the first session with modest ambitions.
Growing it
Flowering runs 63 to 70 days on a medium plant, roughly 100 to 120cm, returning a heavy 610 g/m². THC is recorded at 30 per cent. The record describes dense, trichome-laden buds with deep colouring, which promises both weight and eye appeal at harvest. Standard in her demands, but the resin load rewards a careful trim and a clean pair of scissors. A serious yield to match a serious potency.
