Terp & Tonic by Seedstockers

Terp & Tonic is the Seedstockers Superior strain bred for one thing above all: maximum terpene expression. A cross of Freakum Zkittlez and Ghost Tonic, it produces an overwhelming citrus aroma, a clean and energizing sativa high, and enormous, resinous colas that extract makers love.

Grown from feminized seeds, every plant is a flowering female. This is the full-size photoperiod form of the line, a tall and vigorous sativa-dominant plant that rewards training and generous feeding with heavy harvests.

Expect plants of 120–180 cm (47–71 in) and 9–10 weeks of flowering. Indoor yields reach 550–700 g/m² (1.80–2.29 oz/ft²), and outdoor plants can produce 500–800 g (17.6–28.2 oz) each in open soil.

The breeder lists a 1st Best Solvent Extraction award at the Amsterdam Coffeeshop Awards and a 2nd Best Dry Sift at The North Grow Cup, a clear sign of how well its resin performs in both solvent and solventless work.

Lineage: Freakum Zkittlez x Ghost Tonic

Freakum Zkittlez contributes candy-sweet fruit and a dense coat of trichomes, while Ghost Tonic brings sharp citrus and a lively, clear-headed character. Together they push terpene production to the front of every trait.

Seedstockers selected the line to maximize terpene content without giving up yield or potency. The plant grows tall and vigorous, and the aroma becomes intense from mid-flower onward, which tells you right away how rich the finished resin will be.

Aroma, Flavor and Effect

The aroma is overwhelmingly citrusy: sharp lemon peel and fresh tangerine that fill a room the moment a jar opens. During the grow, this is one of the loudest plants you can put in a tent.

On the palate, Terp & Tonic delivers an intense citrus flavor layered with lemon, tangerine and a sweet herbal finish. It tastes clean and bright, almost like a fresh citrus soda with a twist of herbs, and the flavor holds up beautifully in extracts.

The effect is active, focused and terpene-rich. A clean, motivating sativa high sharpens focus and lifts the mood while staying smooth and even. It suits morning sessions, creative work and social gatherings where you want to stay engaged.

It feels like the first sip of an ice-cold citrus tonic on a hot morning: crisp, refreshing and ready for whatever the day brings.

Growing Terp & Tonic Indoors and Outdoors

Indoors, top early and set up a SCROG to manage the 120–180 cm (47–71 in) frame and spread the colas evenly. Terp & Tonic is a heavy feeder that rewards generous nutrition in mid-flower and can return 550–700 g/m² (1.80–2.29 oz/ft²) under good LED lighting.

Odor control is essential. Paraphrasing the breeder’s own tip: invest in quality carbon filtration, because by around week six of bloom the terpene output is strong enough to be noticed outside the grow space.

Outdoors, plant in open soil where the season is long and warm. The terpene output peaks in warm, dry conditions, and each plant can deliver 500–800 g (17.6–28.2 oz). Give it space, support the heavy colas, and choose a spot where the aroma will not be a problem.
