Ice Kush

Use a compact tent or dedicated room with good airflow, LED or HPS lighting tuned to veg and bloom phases, an extractor fan with carbon filter, and a reliable thermostat and humidistat to keep conditions stable.

Use 18/6 for vegetative growth then switch to 12/12 to induce flowering; maintain consistent schedules to avoid stress and hermaphroditism.

Aim for 20–26°C during the day and a few degrees cooler at night; keep relative humidity around 40–50% during flowering to prevent mould.

Start with a balanced NPK feed in veg then raise phosphorus and potassium during bloom while moderating nitrogen; follow manufacturer dilution rates and watch for nutrient burn.

Ensure strong lateral airflow, reduce canopy density with pruning, maintain lower humidity in late flowering, and remove any mouldy material promptly.

Harvest when trichomes show a mix of cloudy and amber for a balanced effect, typically at the end of the eight to ten week flowering window.

Yes, but prefer sheltered sites or a greenhouse in cooler regions and choose early-flowering phenotypes to avoid autumn rain.

Low-stress training, topping and SCROG work well to open the canopy and increase usable bud sites without over-stressing the plant.

Dry slowly for seven to fourteen days at around 18–20°C and 50% humidity, then cure in jars for several weeks to improve flavour and smoothness.

Monitor regularly for aphids, spider mites and fungus gnats; use neem oil, insecticidal soaps or biological controls and isolate affected plants quickly.
