About Jack O’Lantern Feminized Seeds

About Jack O'Lantern feminized seeds

Jack O'Lantern feminized seeds grow into an indica-dominant hybrid, 60% indica and 40% sativa. The buds are light green and covered in orange hairs, so the plant is as good to look at as it is to smoke. The seeds are feminized, which removes the need to sort out male plants.

What are the effects of Jack O'Lantern?

The effects are relaxed and sleepy. This is a strain that suits the end of the day, when you are sitting back with a coffee or a joint and letting the day wind down. It works as a nighttime strain for that reason. THC reaches up to 25%, which is high, so go slowly with it, especially if you are not an experienced smoker. A small amount goes a long way.

Taste and aroma

Jack O'Lantern combines spicy, earthy and citrus flavors. The earthiness sits underneath, the spice comes through on the exhale and the citrus lifts the whole thing. The puffs are tasty enough that many people keep coming back for more.

Strain characteristics

This is a tall plant. It grows a lot outdoors, reaching more than eight feet, and it needs a garden or a large pot. It is classified as moderate difficulty, so a little experience helps before you start. If you already have some, you will probably enjoy growing it, since it does not demand much effort. It is a strong plant, and it is described as mold resistant, which is a useful trait in a variety that grows large. It does well indoors and outdoors, although the two environments give different results.

Growing Jack O'Lantern indoors

Indoors the plant is shorter, up to about 100 cm (39 in), so leave some headroom under the lamp. Topping the main stem early and tying the branches down creates an even canopy with several main colas instead of a single tall spire. The yield is rated extreme at up to 700 grams (25 oz) per square meter, so give the plants good light and steady feeding to support it.

Growing outdoors

Outdoors you need space. Plan on a large planting hole or a big container, and put the plant where it gets full sun for most of the day. Pruning lower branches and thinning the interior improves airflow, which helps even a mold-resistant plant stay clean. Support heavy branches with stakes or netting once buds begin to swell.

Flowering time and harvest

Flowering is fast, 6 to 10 weeks, and the buds are usually ready after about 9 weeks. Harvest when most trichomes are cloudy. The orange pistils will have darkened and curled by then. Cut the plant, trim off the larger leaves and hang the branches to dry in a dark room before curing.

Who is this strain for?

Jack O'Lantern suits growers with some experience who have space, or those who want a large yield from a strain that is not hard to manage. It also suits smokers who want a relaxing, evening-leaning indica with spicy, earthy and citrus flavors.
