Q: What training methods work best?

Use topping at 3 to 4 nodes, low stress training, and selective defoliation to manage stretch and boost bud sites.

Switch to 12/12 to trigger flowering and keep full light intensity for the 9 to 11 week stretch.

Q: What pests target Astronaut?

Watch for spider mites and thrips on indoor grows and aphids outdoors; inspect the underside of leaves weekly.

Use well-draining soil or coco with regular flushing and stable pH between 5.8 and 6.5.

Flush water-only for 7 to 10 days before harvest to improve smoke smoothness.

Q: How to detect peak potency?
