About the Strain

White Widow is one of the most popular strains on the market, plus it is the perfect strain for beginner growers. This strain has a high THC content which will make you feel more sociable, uplifted, and motivated. A popular strain worldwide, White Widow dates back to the 1990’s and is a Dutch classic, created in the Netherlands.

It is popular in the Dutch coffee shops, with experts debating quite where the original strain come from. Some believe it originates from a Brazilian sativa and a Southern Indian sativa, and some say it is a cross between the Southern Indian sativa and a South American sativa.

Aromas, Flavours and Appearance

White Widow has a pungent and notoriously recognisable smell (you may have to find ways to cover the smell) if you are trying to be discreet!). This strain has a rich and full aroma of earthy, spicy, and pungent peppery tones.

The taste is a lot more sweet, with a deliciously sugary experience, combined with hints of fruit, lemon and pine flavours.

The flowers of White Widow are beautifully covered in white ‘sugar coated’ crystals that seem to have a sparkle as they catch the light. Bright green buds come through the frost-like covering.

Effects and Usage

The THC content in white Widow can go up to some very high percentages, even up to 25%. Because of this, the effects soon kick in, giving users a bound of energy and a euphoric high. This strain is one of the most potent strains worldwide. Using this strain will likely give you a burst of energy, uplift your mood and make you more sociable and chattier.

As it is mood enhancing, people suffering from depression, PTSD or stress often take this strain to help with symptoms. For those looking to use this strain for these purposes, it is recommended to use in smaller does, as taking too much could end up enhancing negative emotions.

As like a lot of strains, cottonmouth can be a common adverse effect of White Widow. To help with this, make sure you are keeping hydrated before and after smoking.


White widow is resistant to bugs, mould, and cooler temperatures, so is quite a tolerant plant to grow and an easy one for beginners to get their hands on.

Best Climate

White Widow loves a warm climate with a good amount of direct sunlight. Ideal temperatures are from around 21 to 26 degrees Celsius. If the temperature does drop a little, this plant can usually survive, making it a resistant little thing.


Whilst in the germination phase, humidity should be kept at around 70%, dropping around 5% lower during the vegetative stage. Once the flowering stage starts, reduce the humidity by 5% each week, until it sits around 30 to 40 percent.

Indoors or Outdoors?

You can grow this strain both outdoors and indoors, although it is said to do particularly well in an indoor hydroponic setting, and when grown in soil with good drainage. The Sea of Green (SoG) method is often used for this strain.

When growing outdoors, ensure your plant has plenty of sunlight and warm temperatures. This strain is great for beginner growers, as long as you provide the basics and some tender-loving care.

Flowering, Yield and Harvest

White Widow typically takes around 8 weeks to flower, although you may also wait until 10 weeks for the white crystals to form even more. If you wait until 10 weeks, you might have to reduce the light they receive from 12 hours a day to 8 hours a day. This will help the plant to stay at its best until harvesting.

This strain produces yields of 550 to 600 grams per plant outdoors, or 450 to 500 gram p/square metre  indoors, so fairly average.

When harvesting your outdoor grow, White Widow should be ready early April in the Southern hemisphere and by early October in the Northern hemisphere.

Plant Feeding

Nitrogen (N), phosphorus (P), and potassium (K) are the main nutrients needed for all plants to grow. Secondary nutrients will also be needed, including Zinc, Manganese, Copper, Iron, Boron and Molybdenum.

Your plant will need more nitrogen in the vegetative stage and more phosphorus and potassium in the flowering stage, to help increase the THC content. Remember to ‘flush’ your plants a week or two before harvesting to get rid of any nutrients and chemical taste.

Other Growing Tips

Pests can be a bit of a problem for both indoor and outdoor growers on White Widow, including mites, aphids, fungi, whiteflies, and caterpillars. It may also be susceptible to bud rot, so ensure you reduce the humidity of the room during the flowering stage. You can try an organic fungicide for the pests, or even make one yourself.

Feminised Seeds

Feminised seeds ensure that the plant you will grow is female. Only the female plants can make the flowers and buds that produce weed (not male plants). By buying feminised seeds you can be sure that you have the best chances for a good harvest!
