Harvest when trichomes show 70 to 90 percent cloudy and pistils mostly amber. In warm climates aim mid to late September.

Q: What training methods work best indoors?

Q: How do I control stretch after flip?

Resistance rates moderate. Maintain airflow and lower humidity during flower to avoid powdery mildew and bud rot.

Dry 7 to 10 days at 45 to 55 percent RH and 18 to 20 C. Jar cure two to six weeks with daily burps the first week.

Q: How long should I flush before harvest?

Flush seven to ten days before harvest using plain pH-balanced water to reduce residual salts.

Q: Which lights suit Rainbow Blast?

Full-spectrum LED or HPS works well. Emphasize blue in veg and red in flower to support bud set and aroma.

Q: How many plants per square meter for indoor setups?

Use 4 to 6 plants per m2 with SCROG. For SOG aim 9 or more small plants per m2 depending on topping strategy.
