What can I say, Dutch Passion F1 White Widow…OMG 😍 Derived from 80’s F1 stock makes for an extremely stable and easy to grow. She yields HEAVY with perfectly formed, rock hard flowers that are LOADED with trichomes so much that it looks like they’ve been sprinkled with super fine diamond dust making this a dream for extraction, and the aroma she lays down will have your mouth watering. These genetics were a massive stacker and easy to cultivate as well. She yielded well and ranks as one of the strongest cultivars I’ve grown.

One reason for the heavy harvest of 270g from a single plant was the generous 60 day period of vegetative growth provided by The Canna Prophet. This allowed the White Widow plants to produce a large root network and a heavily branched final plant. White Widow genetics are particularly vigorous and thrive under optimised conditions. The powerful LED grow lights used in this grow helped produce intense light levels. This in turn allowed the prize winning genetics to step into top gear and produce a very heavy yielding indoor plant.

White Widow 100% organic nutrient feeding schedule

Organic feeding is increasingly popular with home growers. When you are consuming your own buds it makes sense to aim for the highest purity and quality levels. Organic nutrients reassure the consumer that their final buds are free from any artificial residues. For the same reasons home growers pay particular attention to avoid pests – prevention is always better than cure. No responsible grower would spray their buds with potentially harmful pesticides. The 270g final dry yield from the White Widow plant demonstrates that an organic approach certainly doesn’t compromise harvest quantities.

TheCannaProphet has his original White Widow grow review on Growdiaries.com. He has previously enjoyed growing Dutch Passion cannabis seeds, his Power Plant grow review is also well worth reading.

The White Widow grow was steady and unsurprising with no unusual problems or difficulties. This is to be expected from such a well established and fully proven genetic line with multiple cannabis cup wins.

Dutch Passion White Widow seedling stage

White Widow feminised cannabis seeds were germinated in small plastic cups containing a 70/30 blend of coco fibre/perlite. The LED grow lights provided a full spectrum with sufficient blue light to ensure a solid start.

Dutch Passion White Widow vegetative stage

With 60 days of vegetative growth the White Widow had a good start to life. The heavily branched White Widow is known to produce seriously impressive yields when given such lengthy periods of veg growth and this was no exception. The plants were topped (growing tip removed) after 28 days of veg growth which tends to produce a short and stocky growth pattern.

Dutch Passion White Widow flowering stage

Under the powerful LED grow lights the White Widow grew into a heavy yielding plant during the flowering stage. Branches were covered in resinous buds, causing the branches to bow down. White Widow growers often find that supporting the heavier branches is necessary to prevent them snapping as harvest approaches. The side blooms were long with stacked buds. With so many side blooms the final harvest was predictably very heavy.

Her aroma in flower is SUPER strong so keep that in mind, and remember this is not a ‘daytime’ smoke as she hits you like a hammer…HARD! After a 2 week cure in jars she took on a strong, pungent cheese aroma with slight sweet hints mixed in.. The bag appeal is an 11 (out of 10) and she’s got the mouth to check off the last box, leaving a strong diesel kush taste that lingers quite a while….just a ridiculously enjoyable strain to experience and is well suited for relaxing evenings with friends or listening to music! Cultivate some of these beauties from Dutch Passion and I guarantee you won’t be disappointed!


White Widow drying and curing tips

White Widow heavy yielding cannabis seeds in 8 weeks of bloom

White Widow has a famously powerful and pleasant high. To get the best from the buds it helps to time your harvest well and give the buds a good dry and cure to bring out the delicious flavours and terpene profile. She takes an average of 8 weeks in bloom but some growers don’t mind waiting an extra week or two if a particularly powerful and heavy effect is required.

White Widow growers should note that the aroma is exceptionally powerful, pungent and penetrating. A good quality carbon filter is recommended at all times for indoor growers.
