Tips for Growing White Widow Cannabis

Ever wanted to grow your favorite strain? Leafly and Botanicare are teaming up on a series of grow guides that will equip you with all the tips and tricks you need to grow different strains successfully.


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 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.

Flowering Time: 8-9 weeks

Yield: Moderate to low

Grow Difficulty: Difficult

Climate: Mild, temperate environments with temperatures falling between 70 and 80 degrees Fahrenheit.

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.

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.
