Key Lime Jack

Provide strong, consistent light with a 12/12 flowering schedule; LED or HPS setups work well. Maintain even canopy height to ensure light reaches the colas.

Initiate flowering by allowing natural photoperiods to shorten or by switching to 12/12 indoors around week six of veg. For outdoor grows in the UK, aim to have flowering well underway by mid to late summer to finish before autumn.

Watch for botrytis and powdery mildew in damp conditions and aphids in summer. Keep good airflow and inspect regularly to catch infestations early.

Reduce nitrogen and increase phosphorus and potassium once flowering begins. Feed moderately; Key Lime Jack responds well to steady, balanced nutrients.

Yes, low-stress training and topping produce a wider canopy and more even bud development. SCROG systems suit the plant's short-to-medium height.

Dry slowly at 18–20°C and 45–55% humidity until stems snap, then cure in jars for several weeks with daily burps. Proper curing brings out citrus terpenes and smooths the smoke.

It tolerates mild temperature swings but avoid prolonged exposure below 10°C. Cooler nights can accentuate terpene expression but may slow ripening.

Site plants for maximum sun and airflow, remove lower foliage that traps moisture, and harvest early if wet weather arrives. Use preventive fungicides or sulphur as a last resort and follow safe practice.

High humidity increases the risk of bud rot and may force an earlier harvest to preserve yield. Monitor trichomes closely and consider protective covers if late-season rain is forecast.

In high humidity cannabis cultivation, focus on airflow, dehumidification and canopy management to reduce stagnant pockets of moisture. Use drying rooms with controlled conditions and consider greenhouse vents or dehumidifiers to keep relative humidity in check.
