Tips for growing White Widow cannabis

 This article is presented by Advanced Nutrients, a global company raising the bud weights and reputations of cannabis growers since 1999.

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: Easy

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.

    Well that told me next to nothing. Pretty generic. Is it a heavy feeder on Nitrogen, Phosphorus, or Potassium? Any thing not normal that it needs?

  • Frehleygirl .

    Every guide I’ve reads makes it clear to never seal germinating seeds in a bag yet you do. Why?

    • Robert Dutchover-Reynolds

      I always seal my seeds in a bag. my germination process is soaking root riot pod in a root solution(either great white or microbe life hydroponic root/folair spray either at half strength) for 30minutes, I then place seed in the root riot pod after ensuring the pod isn’t holding too much water(only lets water out by squeezing halfway) I place root riot pod with seed in an individual ziploc bag to create a smaller environment to become humid/accept co2. I open the bag daily and breathe in it for fresh air and co2 from my breath.

  • Great plant but yes it can be a Picky plant and soon tells you if shes not happy.
