Rainbow Feminized Seeds

Q: How often should I water Rainbow?

Water when the top 2 cm of soil dries. Provide a deep soak then allow runoff. Reduce frequency in late flower.

Q: What nutrients suit Rainbow?

Start with a balanced NPK during veg. Shift to higher phosphorus and potassium at flowering. Keep calcium and magnesium stable.

Q: Which training methods work best?

Use ScrOG to build an even canopy. Start low stress training early and top at 3-5 nodes.

Q: What temperature and humidity target should I use?

Maintain 22-26°C (72-79°F) in veg and 20-24°C (68-75°F) in flower. Keep RH 40-60% in veg and 40-50% in flower. Prevent mold with strong airflow.

Q: When is the right time to harvest?

Harvest when trichomes show 20-30% amber and pistils are mostly darkened. Flush water 7-10 days before harvest.

Q: How long to dry and cure?

Dry 7-14 days at 18-21°C and 45-55% RH. Cure jars for 2-8 weeks and burp daily during the first week.

Q: What pests should I watch for?

Watch for spider mites, aphids and powdery mildew. Use predatory insects, neem and targeted sprays on affected areas.

Q: Is Rainbow suitable for outdoor grows?

Rainbow performs outdoors in temperate and warm seasons. Harvest before first frost and provide wind protection.

Q: How much pruning should I do?

Topping at 3-5 nodes works well. Remove lower growth and thin inner foliage before flower.

Q: What lights work best indoors?

Full spectrum LEDs at 400-600 μmol/m2/s perform well in flower. Run 18/6 in veg and 12/12 in flower.

Colorful buds

Rainbow produces compact, colorful buds with a fruity, citrus-forward aroma. Terpenes lean toward myrcene, limonene and pinene. Effects start uplifting and move into light body relaxation with mental clarity. Train plants early with topping and low stress training to build a flat canopy and improve light penetration. Expect an 8-10 week flowering window and yields around 400-600 g per m2 under strong light. Monitor humidity in late flower to prevent mold and cure harvested flower for at least two weeks for smoother smoke.
