Lineage: Blue Ice × Blue Ice (S1 Selfed Line)

Blue Ice S1: A Calm, Familiar Blue That Knows Exactly Who It Is

Blue Ice S1 feels like revisiting an old favorite and realizing it still holds up. This selfed line doesn’t try to reinvent anything—it simply brings the original Blue Ice into more precise focus. The goal here was consistency: tighter expression, more predictable structure, and the same cool, blue-leaning character that made the cultivar worth keeping around in the first place.

Blue Ice itself has long been tied to classic Dutch breeding, often credited to Dutch Passion, blending Blueberry heritage with the sturdier backbone you’d expect from White Widow–style lines. That history matters, and it shows. By selfing the original, Blue Ice S1 keeps that calm, dependable personality while making it easier to work with across an entire run.

In veg, this plant settles in without fuss. It doesn’t stretch wildly or stall out—it just grows. The main stem thickens early, side branches come in evenly, and the plant naturally forms a balanced shape. You don’t feel like you’re constantly reacting to it. Instead, you’re just guiding it along.

Aroma & Terpene Profile — Cool Berry, Light Florals, and Clean Earth

The aroma on Blue Ice S1 comes together quietly. Early on, the Blueberry influence is easy to recognize, but it’s not loud. It’s cool, slightly sweet, and clean—more fresh berry than heavy syrup. The scent hangs gently rather than filling the room all at once.

As flower sites continue to take shape, the profile fills out naturally:

• Soft blueberry sweetness
• Light floral notes
• A clean, earthy base
• A superb, almost crisp finish

By the middle of the flowering stage, everything feels settled. Nothing is fighting for attention. After curing, the aroma smooths out even more, with the berry tones blending seamlessly into floral and earthy layers. It’s the kind of profile that feels familiar and steady, not flashy or overworked.

How It Grows — Steady, Readable, and Easy to Manage

Vegetative Behavior & Canopy Formation

Blue Ice S1 grows in a way that’s easy to read, even early on. Internodal spacing remains moderate, making light management straightforward and keeping the canopy open without feeling sparse. It responds well to topping and low-stress training, and it fits comfortably into ScrOG or multi-top setups. Branches bend easily and hold their position, making shaping feel natural rather than forced.

Because this is an S1 line, there’s a noticeable uniformity across plants. That makes dialing in spacing, training, and timing much easier, especially if you’re running multiple plants at once.

Flowering Traits & Development

As the plant transitions into its flowering stage, calyxes begin stacking at a steady, unhurried pace. Trichome density builds consistently, giving the buds a bright, textured look early in the cycle. Stretch is modest—usually around 1.2× to 1.5×—so height stays manageable indoors.

Indoors, Blue Ice S1 typically finishes in 8–9 weeks. Outdoors, harvest timing often falls between late September and early October. Throughout the cycle, the plant holds its structure well and doesn’t lose its rhythm when conditions shift slightly.

Yields & Visual Appeal — Clean Lines With a Cool, Icy Finish

Bud Structure & Aesthetic Traits

Blue Ice S1 produces medium-density buds with clear calyx definition and noticeable trichome density. Color tends to stay bright green early on, with cooler blue or silvery tones showing up later, especially when nighttime temperatures dip.

Expect:

• Consistent bud formation across the run
• Elevated trichome density
• Subtle blue and silver highlights
• Clean stacking and balanced shape
• Strong visual appeal after curing

Production & Garden Output

Yields are solid and reliable, particularly when the canopy is shaped early. The plant’s natural symmetry helps everything develop evenly, whether you’re working in a smaller indoor space or a larger garden.
