Your growing medium must have good drainage. If you usually water your plants once a week, for example, you can decrease it to every 3-5 days if your soil has good drainage. A good tip is to add perlite or lava rock to the medium, as this helps with drainage. Finally, please make sure that you stop feeding nutrients to your White Widow plants around two weeks before harvesting. Otherwise, your precious strain will taste like plant food!
Once you have reached the eight-week mark, or feel that your plant is ready, switch to a 12-hour light cycle. You must expose your crop to 12 hours of continuous darkness each day to force it into flowering. It is at this stage that you can implement the SCROG method. It is imperative that you evenly distribute the light. Otherwise, you won’t achieve maximum yields.
White Widow’s flowering time lasts 7-9 weeks when grown indoors. If you are an outdoor grower, it is ready for harvest by the end of October. Use the Pistil Method to check whether it is harvesting time.
For the record, White Widow performs well at a slightly higher pH than other strains.
Feeding White Widow
Most experts classify White Widow’s yield as moderate to low. If you grow indoors, you could yield up to 18 ounces per square meter. Outdoor growers regularly benefit from a slightly larger yield at 21 ounces per square meter. Other growers suggest that you will receive up to 180 grams of weed (just over six ounces) per plant when you grow indoors.
Once you use this strain, expect a rapid cerebral high, followed by a feeling of euphoria. It is a fantastic social strain because it gives you energy, and ensures you remain aware of your surroundings. Also, it never lets you succumb to couch-lock. It gets the name White Widow from the fact that it looks as if the strain was dipped in sugar. White Widow offers a strong, sweet, and spicy scent coupled with an earthy pine taste.
Patients typically use White Widow as a medicinal strain for conditions such as ADD/ADHD and PTSD. However, you can also use it if you suffer from stress because it is the perfect wind-down smoke.
Flowering Time for White Widow
You need to know that White Widow is one of the hardest marijuana strains to grow, especially outdoors. Generally speaking, most marijuana strains thrive in temperatures of 70-80 degrees Fahrenheit. However, White Widow is capable of absorbing more light at even higher temperatures. We’ve heard reports of growers exposing their plants to temperatures of up to 90 degrees.
There are a host of safe fungicides on the market that won’t expose your White Widow plants to nasty chemicals. Alternatively, you can try a homemade solution. We find that a combination of chili pepper powder and tobacco juice works wonders for handling mites. You can even mix soap and dish detergent to remove spiders. Typically, this solution breaks down into non-toxic elements within a week.
Climate: Mild, temperate environments with temperatures falling between 70 and 80 degrees Fahrenheit.
Flowering time: 8-9 weeks
Yield: Moderate to low
Indoor/outdoor: White Widow is picky about its climate and feeding. By keeping White Widow indoors, you’ll have a better chance at keeping it healthy and happy so that it can produce the famous trichomes that gave it its name.
Grow techniques: Green House Seeds recommends using the SCROG (screen of green) method with White Widow. Fill an indoor grow space with plenty of starts and begin developing a healthy canopy. Prune beneath the screen to remove any unnecessary vegetation into the first week or two of flowering, but make sure to stop there to prevent stress on the plants. White Widow does well in either a soil or hydroponic setup.
Strain overview: White Widow is a classic Netherlands hybrid first produced by Green House Seeds in the 1990s. It’s a cross between a Brazilian sativa landrace strain and a South Indian indica. One of the original high potency strains, White Widow is covered in resin-tipped trichomes and offers an incredibly well-balanced high to relax both mind and body.
Grow difficulty: Easy
Feeding: Keep the plant growing strong in the vegetative state with a healthy supply of nitrogen. As the plant begins to flower, flush the soils and prepare the plant for nutrient formulas with higher phosphorus levels.
After your seedling comes out of the soil, the leaves should be completely green, if you see the cotyledons yellow or if you don’t see the one-fingered cannabis leaves, then something’s wrong.
In this grow cycle, the White Widow has been grown under specific conditions, as you can see, the temperature, humidity, and pH were controlled closely.

In this stage you should maintain a 60% relative humidity and a temperature around 23° C, a high humidity is ideal for baby cannabis plants because it helps them develop the roots better.
