About Silver Widow
Genetics & strain profile
Silver Widow is a feminized strain that is the result of careful breeding and selection by Quebec Cannabis Seeds. It is a balanced hybrid with 18 to 21% THC, and the page says it is best suited to intermediate growers. A first-time grower can still try it, but should read up on training and feeding before starting. The parents are not named on the page, so we will not guess at them. It has no reviews yet, so everything here comes from the breeder’s description and not from customer grows, and we will not claim results beyond that. The THC range is moderate, so treat it as a range and not a promise. Our seeds are guaranteed, so if a seed does not come up, contact us.
How Silver Widow grows
This is a photoperiod strain, so it flowers when you move to 12/12 indoors or as the days shorten outdoors. Flowering takes 65 to 75 days, and the page gives up to 700 g/m² indoors, which is a high figure and best read as a best case. Outdoors, the harvest is typically ready in early October, with up to 600 g per plant in optimal conditions. In Quebec and Ontario, start indoors in April, plant out after the last frost and use a cover or greenhouse for the last weeks of autumn rain. A balanced hybrid is easy to shape: top early, train the branches wide and keep air moving through the canopy, because heavy colas hold moisture late in flower. Harvest by the trichomes, not by the calendar. Check your local rules before you plant. A light hand with nutrients is the safer path with a high-yielding plant.
Taste, aroma and effect
Earthy and spicy, with subtle herbal undertones. The effect is described as euphoric, relaxing and balanced. At 18 to 21% THC it is moderately strong, and newer consumers should still start with a small amount, since effects vary from person to person. Spicy, earthy plants tend to smell, so plan for odour control indoors. Reviews are the best guide to how a strain behaves in real grow rooms, so check back as customers add theirs.
