WHITE WIDOW strain Overview

White Widow seeds represent a classic strain with a stellar reputation. The strain is aptly named after its appearance: The buds are hard, white, and covered by a thick crystalline layer. White Widow is the perfect choice for anyone looking for a highly potent strain with balanced effects. 

This legendary strain won the 1995 High Times Cannabis Cup, and its strong aroma and flavor make it the perfect choice for experienced stoners. These easy-to-cultivate seeds are a favorite among cannabis growers in the US, Canada, and beyond. Here is everything you need to know about the White Widow weed strain. 

What are the origin and genetic composition of White Widow feminized seeds?

White Widow is originally a product of Green House Seeds, a veteran Dutch seed company. It was developed in the 1990s by crossing Brazilian Sativa and South Indian Indica strains. The average THC for the strain is about 20%. White Widow seeds are Indica dominant (60% and 40% Sativa).

White Widow attains a height of about 190cm at maturity and has dense buds, like many other Indica strains. It is easy to tell the strain’s buds apart due to their spring green hues, orange pistils, and heavy frosty trichomes, which cover them entirely, making it hard to break them.

What are the effects of the White Widow strain?

The Sativa-induced effects from White Widow manifest first during a session. The effects are characterized by a robust cerebral rush that will leave you creative, positive, uplifted, and energized. The effects last only a few minutes and are replaced by calming, Indica-induced effects.

The body stone delivers cerebral and physical relaxation that takes away all the worry, stress, aches, pain, and tension. This makes White Widow an excellent winding down strain after a long day. You can expect mild couch-lock and a serious case of the munchies. 

Can the White Widow be used medically?

Yes. White Widow has numerous health benefits. The strain can manage chronic pain, inflammation, anxiety and stress disorders, eating disorders, and insomnia.

What does the White Widow strain smell and taste like?

White Widow has a rich composition of aroma and flavor, making it an incredible strain for novice and experienced marijuana users alike. When the buds are broken apart, they let out an incense-like aroma with hashy notes. During combustion, the strain lets out a mix of fruity and spicy aroma, with skunky notes. 

White Widow is not a discreet strain as the aroma is intense and fills up the room as soon as the buds are broken apart. The strain has a smooth smoke with an earthy aftertaste after the inhale and exhale, lasting many hours after a session.

How to grow White Widow seeds?

White Widow can be cultivated from either clone or seed and is moderately easy to grow, especially for experienced growers. It is resistant to mold, cold temperatures, and pests and can survive indoors and outdoors. The White Widow weed strain thrives in a sunny and warm climate, so replicating the same conditions indoors guarantees impressive yields.

This is a forgiving strain that can withstand minor fluctuations in optimum conditions. Here are the essential management tips for the White Widow strain:

  • Keep the temperature range between 20 and 27 degrees Celsius.
  • Keep the humidity levels between 30% and 40% during the flowering stage.
  • Trim the fan leaves regularly during the flowering period to increase light penetration.

The strain takes 8 to 10 weeks to complete the flowering stage in indoor and late October in outdoor conditions. The yield for indoor-grown White Widow is 750 to 800 grams/m2 and 800 to 900 grams/plant in outdoor conditions, making it one of the most-yielding strains.

First Time

I was hesitant to try White Widow seeds at first, but I am so glad that I did. The high is absolutely amazing and it is definitely a favorite of mine. The smell is authentic and the taste is relatively bland, but that doesn't bother me because the high is well worth it. I would definitely recommend this to anyone looking for an extreme high.

Nice people and fast delivery

I was really happy with the quality of the White Widow Cannabis Seeds Feminized that I ordered from UCS. All 20 of the seeds germinated and grew into healthy plants. I've used other seed companies in the past, and have had a lot of trouble getting seeds to germinate, so I was really impressed with the quality of UCS's products.

7.5 oz at 63 days, super soil, ph 6.2 @ 7-900 ppm
Sweet mild skunk flavor, long lasting relaxing high, I decided it is good enough to keep for a while , I still have four more seeds, every seed will be a little different. that's how we gind the fire strains. I have kept strains for 12years continuous, I am searching for the keepers. This takes so much time and discipline "

"My first of 5 seeds is very very big producer, itis only 26 inches tall and easily has 224 grams
I don't know about the potency yet, the smell is nice but mild, it really doesn't have a lot of trichomes so hopefully it will still be potent
