About Northern Lights XTRM ® Feminized Seeds

About Northern Lights XTRM feminized seeds

Northern Lights XTRM feminized seeds grow into an indica-dominant hybrid, 70% indica and 30% sativa. It is rated high in both THC and CBD, with THC reaching up to 20%, and that pairing gives it a well-rounded character. The seeds are feminized, so you can expect every plant to flower.

What are the effects of Northern Lights XTRM?

The effects are euphoric and relaxed, and the high settles over the body and the mind together. It is a strong, calm high, the kind people pick when they want to switch off and drift for a few hours. The indica share keeps the body feel heavy and loose, while the euphoria keeps the mood bright. The high CBD rating does not make it mild, so treat it with respect if you are new to cannabis.

Taste and aroma

The flavor is sweet and spicy, with herbal and tropical notes in the mix. The sweetness is the first thing you pick up, and the herbal tone lingers on the exhale.

Strain characteristics

The plant is moderate in difficulty, so it helps to have some knowledge and experience before you grow it. Plant size is average. It is a hungry plant, and growers who want to get the most from it should plan a steady feeding schedule. Use a fertilizer suited to each stage and watch the leaf tips for burn if you push the dose too far. Watering needs to be consistent, because the roots like a damp medium that is never soggy.

Growing Northern Lights XTRM indoors

Indoors the plant grows up to about 80 cm (31.5 in), which makes it a good fit for a small tent or a closet grow. Topping once and spreading the branches builds an even canopy. Yield can reach 550 grams (19.4 oz) per square meter, which is high, and flowering takes 6 to 10 weeks.

Growing outdoors

Outdoors the plant can reach about 200 cm (6.5 ft), which is more than twice its indoor height. It handles cold, Mediterranean and warm, dry climates well, so it is a flexible choice if your summers are short or your nights turn cool early. Give it a spot with morning sun and shelter from strong wind, and keep feeding steady through the main growth phase.

Flowering time and harvest

With a fast flowering time of 6 to 10 weeks, this plant finishes earlier than many strains. That is useful outdoors, where an early harvest lowers the chance that autumn rain reaches your buds. Check the trichomes and cut when most are cloudy, with a few turning amber.

Who is this strain for?

Northern Lights XTRM suits growers with a little experience who want a compact plant with a high yield and a flexible climate range. It also suits smokers who like a euphoric, relaxed indica effect with a sweet, spicy and herbal flavor.

    Big frost nugs

    Great strain, vegged 24hrs 30 days 1 gallon pots 7 wks of flower. Got massive colas, sticky crystals all over, hard to see how far along due to the white widow in this strain. Hardly any brown hairs, also trichromes have some cloudiness.

    Nice frosty buds

    Very happy with the quality of the buds that have grown. Planted 10 seeds and only got 4 to pop, but what I did get is definitely choice buds.
