Rainbow Cake Feminized Seeds

Q: How much light does Rainbow Cake need during flower?

Aim for 600 to 900 PPFD during the 12/12 flower period. Keep light uniform across the canopy.

Q: What nutrient schedule works best?

Use a balanced veg feed then shift to higher phosphorus and potassium during bloom. Reduce nitrogen after week three of flower.

Q: When should you top or train this strain?

Top once during week two of veg. Start low-stress training immediately after topping to widen the canopy.

Q: How do you control smell during late flower?

Use a carbon filter and increase ventilation. Install an inline fan and maintain negative pressure to keep odor contained.

Q: What pests target Rainbow Cake?

Watch for spider mites and thrips. Inspect under leaves weekly and treat infestations early with targeted miticides or insecticidal soaps.

Q: When should you flush before harvest?

Begin a water-only flush 7 to 10 days before harvest for smooth smoke. Reduce additives and maintain pH during the flush.

Q: What is ideal humidity during flower?

Keep relative humidity between 40 and 50 percent during flower to reduce mold risk and support resin production.

Q: How long should you veg Rainbow Cake for best yields?

Veg for four to six weeks to build a strong canopy. Longer veg increases yield but raises final plant height.

Q: How should you cure Rainbow Cake buds?

Dry to 10 to 12 percent moisture over 7 to 10 days, then jar at 62 percent RH. Burp jars daily for two weeks, then weekly for a month.

Q: What signs show nutrient burn or deficiency?

Leaf tip browning indicates nutrient burn. Yellowing between veins suggests magnesium deficiency. Adjust feed strength and pH after spotting symptoms.

Rainbow Cake combines creamy vanilla and bright berry notes with a lifting head buzz and steady body relaxation. Genetics come from Wedding Cake x Gelato. Expect 24 to 26 percent THC and low CBD. Veg four to six weeks, then flower 8 to 10 weeks. Use low-stress training early and strengthen the canopy for even light penetration. Maintain 600 to 900 PPFD in flower, 40 to 50 percent humidity, and a bloom feed higher in phosphorus and potassium.
