Skyrocket

Skyrocket Cannabis Seeds by Amsterdam Genetics

Skyrocket is a feminised cannabis seed from Amsterdam Genetics that crosses Skywalker Saga with Grapefruit Superstar to produce a compact, indica-dominant plant with serious yield potential. At 60% indica and 40% sativa, she delivers bold skunky-citrus flavours and a full-body, deeply relaxing effect — all from a plant that barely tops a metre tall. If you're short on space but big on ambition, this is the one to grow.

Why Skyrocket Cannabis Seeds Deserve Your Grow Space

We've seen plenty of indica-dominant strains come through, and the ones that stick around tend to share a few traits: easy to grow, generous yields, and flavour that actually delivers on what the genetics promise. Skyrocket ticks all three boxes without demanding much from you in return.

The parentage here is worth paying attention to. Skywalker Saga brings that deep, skunky indica backbone — earthy, heavy, reliable. Grapefruit Superstar adds the citrus brightness and a bit of sativa spark so you're not growing a one-note plant. The result is a hybrid that smells like a grapefruit rolled through a skunk den, and we mean that as a compliment. When you crack open a cured bud, you get bold spicy and earthy notes layered under that citrus punch. It's not subtle, and it's not trying to be.

The honest limitation? At around 1 metre tall, she's not going to fill a large outdoor plot the way a towering sativa would. But that compact stature is exactly the point — Skyrocket was bred for growers who need to keep things discreet or who are working with a smaller tent. Compared to something like Amsterdam Genetics' Lemon Ice, which can stretch taller and requires more training, Skyrocket practically manages herself. A bit of standard pruning and feeding is all she asks for.

Skyrocket Seed Variant and What You Get

Growing Skyrocket Seeds — What to Expect

Here's where Skyrocket really earns her keep. She's one of those strains that doesn't punish you for being a few days late on feeding or slightly off on your light schedule. Robust and resilient, she handles minor mistakes without throwing a tantrum. We'd still recommend keeping your environment stable — consistent temperature, proper airflow, regular watering — but she's forgiving enough that newer growers won't lose sleep over her.

Indoor growers, you're looking at 750g/m² in a 7-8 week flowering window. That's a seriously productive return for a plant that stays around a metre tall. You won't need to do heavy LST (low-stress training) or ScROG netting unless you want to — she naturally stays compact and bushy, which means light penetration to lower bud sites is decent without much intervention. A few rounds of defoliation during veg and early flower will help, but she's not the type to turn into an unruly jungle.

Outdoor growers in warmer climates can push towards 1kg per plant in ideal conditions. That's a big number for a small plant. She'll do well in Mediterranean-style climates, but her resilience means she can handle cooler, less predictable weather too. Just make sure she gets enough direct sunlight — 6+ hours daily minimum — and she'll reward you.

1. Germinate your Skyrocket seeds using the paper towel method or directly in a starter plug — taproots typically appear within 24-72 hours.
2. Transplant seedlings into their final container once they've developed 2-3 sets of true leaves. A 15-20 litre pot works well for indoor grows.
3. Maintain 18/6 light during vegetative phase. She doesn't need a long veg — 3-4 weeks is plenty given her compact growth pattern.
4. Switch to 12/12 light to trigger flowering. Expect buds to start forming within the first 10-14 days.
5. Prune lower growth that isn't receiving light — this redirects energy to the main cola and upper bud sites.
6. Feed with a bloom-specific nutrient schedule once flowering begins. Skyrocket responds well to standard indica feeding ratios (higher P and K).
7. Monitor trichomes during weeks 7-8. Harvest when trichomes shift from clear to milky with some amber — this is where the full-body indica effect peaks.
8. Dry in a dark, well-ventilated space at around 18-21°C and 55-60% humidity for 7-10 days, then cure in glass jars for at least 2 weeks.

Flavour, Aroma and the Skyrocket Effect

This is where Skyrocket gets interesting. Crack open a jar after a proper cure and you're hit with a dominant skunky aroma cut through with sharp citrus — that Grapefruit Superstar parent doing its work. It's pungent. Your carbon filter earns its keep with this one. The smell fills a room quickly and lingers on your fingers.

The taste follows through on the nose. Bold, spicy earthiness sits at the base, with grapefruit and citrus notes layered on top. It's a thick, satisfying smoke — not delicate or floral. Think more along the lines of a proper old-school skunk that someone decided to squeeze a grapefruit over. The exhale leaves a spicy, slightly sweet aftertaste that sticks around.

With a THC content averaging around 20%, the effect is fast-acting and firmly indica-leaning. Expect a full-body relaxation that settles in quickly and deepens over time. It's the kind of effect that starts in the shoulders and works its way down — not a couch-lock knockout necessarily, but definitely one for the evening rather than a productive afternoon. The 40% sativa genetics keep a gentle mental clarity in the mix, so you're relaxed but not completely switched off. According to research on cannabis and cardiovascular effects, THC may temporarily increase heart rate in some individuals (Healthline), so if that's something you're sensitive to, start slow and see how she sits with you.

Skyrocket vs Other Amsterdam Genetics Strains

Skyrocket wins on yield-per-square-metre and flowering speed. If you're optimising for output in a small space, she's the strongest pick in the Amsterdam Genetics lineup. Lemon Ice is a better shout if you prefer a lighter, more energetic daytime profile, and Tangerine G13 sits somewhere in between — fruitier but less productive.
