Bluntz

Aim for 50–70% relative humidity in veg and drop to 40–50% in flowering to reduce the risk of bud rot and mould.

Use a moderate nitrogen feed in veg, then switch to higher phosphorus and potassium in bloom; follow your nutrient manufacturer's ppm recommendations and adjust to plant response.

For humid climate cannabis growing maintain strong airflow, remove excess lower foliage, use dehumidifiers or ventilation, and consider harvesting early if a wet spell threatens.

Yes — topping, low-stress training and SCROG work well to open the canopy, increase light penetration and boost yields.

Flush for 7–10 days ahead of harvest if using synthetic nutrients; with organic feeds you may reduce or skip flushing but still finish with plain water to improve smoke quality.

Bluntz performs well outdoors in southern UK regions if sheltered from prolonged rain and given good airflow to limit mould development.

Check trichomes with a loupe; harvest when around 70–80% are cloudy with 20–30% amber for a balanced effect, or adjust to preference.

Feminised seeds are reliable; use a warm, moist environment like a paper towel or sow directly into a light compost and keep at around 20–25°C.

Dry slowly at 10–12°C and 50% RH for 7–10 days, then cure in jars, burping daily for the first two weeks and less often thereafter to develop flavour.

Indoors use good carbon filtration and sealed tents; outdoors plant away from public sightlines and consider companion planting to mask odours.
