Before there was a feminized version, there was this one. Ice Cream Haze was first released by Dutch Passion as regular seeds only, the pure F1 result of breeder Antonio’s work, and it remains the choice for growers who want the genetics in their original form, males and all.
The recipe brings together a Crockett’s Haze mother, a vigorous, fast-growing Sativa known for production of 750+ g/m² (2.46+ oz/ft²), with Ice Cream Cake (Gelato x Wedding Cake) pollinators. Antonio, credited with 35 cannabis cups over seven years, selected both a male and a female Ice Cream Cake for the project. The female gives compact, potent, easy-to-trim buds; the male adds strong branching, a powerful stem-rub aroma and unusually frosty sugar leaves.
A pack of 10 regular seeds will produce a roughly 50/50 mix of male and female plants. That is exactly what breeders and pheno hunters want: a broad spread of F1 expressions to choose from, plus males to study and use for pollen.
Why Grow Ice Cream Haze from Regular Seeds?
Regular seeds are the traditional way to work with a cross, and Ice Cream Haze rewards that approach. Because it joins a near-pure Sativa with a slightly Indica-leaning dessert hybrid, the females in a regular pack can vary noticeably. Some lean hard into spicy, fruity Haze with long spears and slower finishes; others echo Ice Cream Cake with denser buds, a creamy Gelato-style nose and quicker ripening. The plants that blend both are the ones to keep.
Pop a full pack, sex the plants in early flowering and take cuttings of every female before flipping. Once you have smoked and compared the harvests, keep the standout as a mother plant and run her as clones for consistent crops.
The males are useful too. Ice Cream Haze males inherit traits from the Ice Cream Cake father, including sturdy branching and frosty leaves, so watch for vigor, structure and a loud stem rub when choosing a pollen donor. Collect and store pollen to dust a single branch of a favorite female for your own seeds, or cross into other lines.
Flavor, Effects, and Growing the Females
Flowering females are very aromatic: spicy, penetrating Haze over tropical fruit and smooth ice cream, getting intensely strong toward harvest. A strong exhaust fan with a fresh carbon filter is a must. The taste usually tilts toward the Haze, spicy yet fresh and fruity.
The effect is long-lasting and leans cerebral: an energetic, euphoric up-high that can creep, building over time before easing into a dreamy, relaxed state while you stay present. It is strong enough to be a head stash for seasoned consumers.
Growth is vigorous with stiff branches and short to medium internodes. Expect a 2.5-4 week stretch after the switch to 12/12 and main colas of 25-50 cm (9.8-19.7 in) on untrained plants. SOG and SCROG give the highest returns; females yield about 600 g/m² (1.97 oz/ft²) indoors, up to roughly 700 g/m² (2.29 oz/ft²) in expert hands. Keep the room at 21-27 °C (70-81 °F) for the smoothest ripening.
Outdoors, stick to warm, sunny, dry climates, where females can reach 3 m (9.8 ft) and produce 0.5-1 kg per plant (17.6-35.3 oz/plant). Remove males early from outdoor beds unless you want seeded buds.

FAQ
What is the difference between Ice Cream Haze Regular and feminized?
The regular version was the original release and produces both male and female plants in roughly equal numbers. The feminized version yields flowering females. Regulars are favored for selecting mother plants, collecting pollen and breeding.
How many of the seeds will be female?
Regular seeds give roughly a 50/50 split between males and females, so a pack of 10 will usually produce around five females, though the exact ratio varies.
Can I use Ice Cream Haze Regular for breeding?
Yes. You get true males to use as pollen donors. Look for vigorous males with strong branching, frosty leaves and a loud stem rub, traits passed down from the Ice Cream Cake father. As an F1 hybrid, any seeds you make will show more variation.
How do I pick a keeper mother from Ice Cream Haze Regular?
Take cuttings from every female before flowering, then grow them out and compare yield, aroma, structure and effect. Keep the clone of the winning plant as a mother. The phenotypes blending spicy Haze with creamy Ice Cream Cake are usually the most sought after.
How long do Ice Cream Haze Regular females take to flower?
About 8-10 weeks after switching to 12/12. Haze-leaning phenotypes may sit at the longer end, while Ice Cream Cake leaners tend to finish faster.
