From Vision to Leading Provider

Grow Island was founded in Vienna in 2015 – built on the belief that quality, knowledge, and diversity are the foundation of successful cultivation. Today, we are much more than a local shop: we are one of the best-known names in the German-speaking cannabis community when it comes to authentic genetics, healthy clones, and transparent information.

Our mission is simple: make the best genetics accessible to you – whether you are a beginner, collector, or seasoned grower. We work with international breeders and cutters and guarantee discreet EU-wide shipping.

Why Clones Are the Better Choice

Many growers ask: should I start with seeds or clones? The answer depends on your goals. Clones are genetic 1:1 copies of a mother plant, which means the result is predictable: aroma, effect, and yield are identical to the original.

Seeds, on the other hand, may produce different phenotypes – some strong, some weak. Exciting for breeders, but a risk if you need consistency.

• No phenotype lottery: you know exactly what you’re getting.
• Stability: every clone develops the traits of its mother.
• Time saving: skip the germination stage and start growing immediately.
• Faster harvest: because clones are already established.

Your Clone Has Arrived – What’s Next?

To keep your clone healthy and thriving, follow these simple steps right after it arrives:

1. Unpack: Carefully open the package and check the plant (fresh leaves, moist medium).
2. Light & climate: Provide 18 hours of light daily (LED or fluorescent), 22–26 °C, and 60–75% humidity.
3. Transplant: Start in 0.5–1 L pots, then move to 3–5 L. Use loose soil or coco for root development.
4. Watering: Keep the medium evenly moist, never waterlogged. Roots need oxygen.
5. Acclimatization: Allow 5–7 days of rest without training or nutrients. Afterward, you can start topping, LST, or gentle feeding.

Tips for Beginners and Pros

• Beginners: Start with soil – it’s more forgiving than hydro or coco.
• Pros: SCROG or SOG techniques deliver stable results with clones.
• Ventilation: A small fan prevents mold and strengthens stems.
• Humidity: Clones like 70% at first, later 50–60% is enough.
• Training: Begin only after the plant has rooted well (around 10 days).

Common Mistakes to Avoid

• Overwatering: too much water suffocates roots.
• Cold conditions: growth slows below 20 °C.
• Feeding too early: fresh clones don’t need nutrients immediately.
• Excessive stress: topping or bending only after acclimatization.

FAQ – Frequently Asked Questions

How long do clones survive shipping?

With our special packaging, they stay fresh for several days. We recommend unpacking immediately upon arrival.

Do I need to transplant clones right away?

Yes, small pots with fresh medium help roots spread quickly.

Can I grow clones outdoors?

Yes, once temperatures are consistently above 18 °C. Otherwise, indoor is safer.

When should I start feeding nutrients?

After 5–7 days, once the plant has produced new roots.

How do clones compare to seed-grown plants?

Clones usually establish faster, offering stable and predictable results compared to seeds.
