The muse of Dutch coffee shops
One of the most popular and celebrated cannabis strains worldwide, White Widow has dominated the menu of Amsterdam coffee shops since its introduction in the 1990s. It won the High Times Cannabis Cup in 1995 and has not stopped bagging awards since, quickly joining the ranks of other early hybrids like Northern Lights and Haze.
White Widow was bred by combining two landraces — an Indica from southern India and a Sativa hailing from Brazil. The result is a sugar-dipped budchild highly valued in creating hash and other concentrates due to its incredible resin production. Making cannabis connoisseurs drool with excitement, it also shares a full-bodied, earthy aroma and potent effects brought about by 18 to 25% THC composition.
This balanced strain delivers a smooth high that leaves tokers uplifted and relaxed without the feeling of heaviness, which is why it is a popular choice amongst people who want to steer clear from getting couch-locked. Those looking to reignite their creative spark or come out of their introvert shell can also count on this cannabis, along with medical marijuana users seeking relief from stress, depression, pain, and fatigue.
White Widow’s strong landrace genetic foundation has made it a valuable plant in cannabis crossbreeding, birthing popular hybrids like White Russian, White Rhino, and Blue Widow. It is also one of the most straightforward strains to deal with and is heavy-yielding in favorable conditions. Home-growers can cultivate this plant using regular, feminized, and autoflower seeds.

A photoperiod White Widow matures into a medium-sized plant, while the autoflowering version is smaller.She has a thick, Indica-shaped structure with leaves of various green tones and large, heavy, and dense buds. Known for her way above average resin production, the thick coat of trichomes on her flowers’ surface turns frosty alabaster once they reach the peak of their potency. It gives the cannabis an almost white appearance, which is how the strain earned her name.
Besides being insanely resinous, White Widow, whether photoperiod or autoflowering, is a relatively easy plant to grow. She can be raised indoors or out, in soil or any hydroponic system. The strain is also highly resistant to common diseases that spread in marijuana gardens but may need some pruning to allow ample light penetration and air circulation. This should prevent moisture buildup and high-moisture-related issues.
Feed White Widow with a healthy supply of nitrogen for optimal growth during the vegetative phase. Once flowering begins, perform a flush to prepare the cannabis plant for phosphorus-heavy nutrient solutions. To ensure the strain thrives, also grow her in mild, temperate environments with temperatures ranging between 70 and 80°F.
If you plan on growing outdoors, bear in mind that White Widow flourishes best in warm, dry, and sunny locations. The long summers and moderate autumn conditions of regions with a Mediterranean climate are most favorable to this strain and can yield 600 grams per plant. She can be cultivated in colder places, but be on the lookout for moisture-related concerns, especially during the final weeks of the blooming phase. The sun-grown flowers should be ready for harvest by late October.
Thanks to White Widow’s sturdiness and manageable size, indoor growing is pretty straightforward. She works well in a Sea of Green (SOG) setup and can produce 510 grams per square meter with the combination of this method and the right climate conditions. This female spends 8 to 9 weeks flowering.
White Widow Auto goes from seed to ripe for reaping in as fast as 8 to 9 weeks and only reaches up to 110cm high. She thrives in warm and sunny places, producing a decent harvest of about 190 to 240 grams per plant. In the northern hemisphere, growers can harvest as early as April up to October.
If grown indoors, White Widow Auto shares 400 to 450 grams per square meter. You can achieve such harvest size by putting the plants under 600 Watt HPS for 18 to 24 hours a day and employing yield-boosting techniques like the Sea of Green (SOG) method. Of course, climate conditions must also be favorable.
What’s the best grow technique for White Widow?
Whatever White Widow seed type you prefer to grow, the Sea of Green, or SOG, can help maximize the output. It is a cannabis growing technique that involves planting a large number of small plants close together. The resulting canopy of leaves creates a “sea” of green which helps to maximize light absorption and encourages the plants to flower rapidly. While SOG requires more initial investment in terms of time and money, it can produce larger yields in shorter periods of time than other growing methods. When done properly, the SOG technique can be an effective way to produce high-quality cannabis plants.
There are a few key things to keep in mind when using the Sea of Green method. First, starting with healthy, well-rooted clones or seedlings is crucial. Second, the plants must be spaced evenly so that they have enough room to grow without crowding each other out. Finally, proper nutrition and watering are essential for ensuring that the plants stay healthy and produce good yields. With a little bit of care and attention, the Sea of Green method can be an excellent way to grow cannabis plants.
What are the basic requirements for a cannabis grow tent?
A cannabis grow tent is a contained growing environment specifically designed for cannabis plants. Cannabis grow tents are made out of durable, light-proof fabric that reflects light back onto the plants, and they often come with features like built-in ventilation and easy access ports. Most grow tents also have a reflective inner lining to maximize the amount of light that reaches the plants. The ideal size for a cannabis grow tent is 3’x3’x6.5’, but larger tents are also available. When choosing a grow tent, it is vital to ensure that it has enough ventilation and that the fabric is thick enough to block out all light. Cannabis grow tents provide an ideal growing environment for cannabis plants, and they are an essential piece of equipment for any indoor grower.
How to hide the pungent smell of White Widow?
Cannabis gardens can have a strong and pungent smell, especially when the plants are flowering. This can be a problem if you live in an area where cannabis is not legal or if you simply don’t want your garden to be too noticeable. There are a few things you can do to help hide the smell of your cannabis garden.
One option is to plant other strong-smelling plants nearby. This can help to mask the smell of the cannabis, making it less noticeable. Another option is to use a carbon filter in your grow room. This will remove some of the smell from the air, making it less likely to be detected. Finally, you can simply keep your garden well-ventilated. This will help disperse the smell so that it is not as concentrated in one area. By taking some simple precautions, you can help to keep your cannabis garden a little bit more discreet.
