About Girl Scout Cookies XTRM ® Feminized Seeds

About Girl Scout Cookies XTRM feminized seeds

Girl Scout Cookies XTRM feminized seeds produce an indica-dominant hybrid, 80% indica and 20% sativa. THC reaches up to 21%, which is high. If you are new to cannabis, a strain at this level hits harder than most people expect, so take your time, learn what amount suits you and build from there. The seeds are feminized, which means the plants you germinate will flower without males getting in the way.

What are the effects of Girl Scout Cookies XTRM?

The effect profile is creative, euphoric, relaxed and social. Most of the relaxation is in the body, with a warm, settled feel that comes on gradually. The head side is bright rather than foggy, and it tends to make conversation easy, which makes it a natural pick for an evening with friends, a party or an afternoon of working on something creative.

Taste and aroma

The flavor is sweet and earthy, and it is easy to get absorbed in it. The finish is chocolatey with a hint of mint, and a citrus note shows up alongside the sweetness. Dry and cure the buds slowly and those flavors stay intact.

Strain characteristics

The plant looks as good as it smells. It forms green calyxes wrapped in purple-tinged leaves, with bright orange hairs running through the flowers. How much purple you get depends on the individual plant and the conditions. Difficulty is moderate, so it suits growers who already know the basics.

Growing Girl Scout Cookies XTRM indoors

Indoors the plant stays at a manageable height of up to 120 cm (47 in), so it fits a standard grow tent without much trouble. Plant size is average. Topping once or twice and bending branches outward helps light reach the lower sites, and a light defoliation in early flower keeps air moving through the canopy. Expect up to 550 grams per square meter indoors, which is a high yield.

Growing outdoors

Outdoors it can reach up to 170 cm, still not a tall plant, and the yield can climb to 700 grams per square meter. It is suited to Mediterranean and temperate climates, with plenty of sun and mild, dry weather toward the end of the season. A spell of damp weather before harvest is the main risk, so check regularly for mold in the center of larger flowers.

Flowering time and harvest

Flowering falls in the fast range of 6 to 10 weeks, with the typical finish between 7 and 9 weeks. Rather than counting days, watch the trichomes. When most are cloudy and a few have turned amber, the buds are ready. Waiting a little longer gives a heavier body feel, and cutting earlier gives a lighter one.

Who is this strain for?

This strain is a good fit for growers with some experience who want a manageable, high-yielding plant with a sweet, minty-chocolate flavor. It is also a fit for smokers who like a social, creative and relaxed effect, as long as they respect the THC level.

    Best strain

    This is one of the best strains I've grown. Very strong and productive plant. All blossoms and leaves stick hard. Grow on aroponic. Always get good clones from the mother plant. THC always very high and very strong, something for the experienced user.
