Highrise

Highrise is best for growers with some experience because it needs active humidity and airflow management, but it is forgiving with basic training and nutrient control.

Use a moderate N-P-K schedule in vegetative growth and switch to higher phosphorus and potassium during flowering, watching EC levels to avoid nutrient burn.

Keep RH below 50% during late flowering, use dehumidifiers, maintain good airflow and remove lower larfy growth to reduce disease pockets.

Topping and LST both work well to build an even canopy and maximise bud sites; combine techniques to control height in smaller rooms.

Harvest when trichomes show a mix of cloudy and a few amber heads, typically near the end of the 8 to 10 week flowering window for peak cannabinoid balance.

Dry to 55-65% RH until stems snap, then cure in jars for at least two weeks, ideally a month, burping regularly to develop flavour and smoothness.

Spider mites and aphids can appear indoors; keep cleanliness, use sticky traps and introduce predatory mites or safe insecticidal soaps when necessary.

Outdoors it can finish in sheltered spots but needs protection from prolonged rain and wind common in northern locations to avoid rot and bud damage.

Highrise is adapted for controlled northern climate cannabis growing provided growers manage humidity and give protection outdoors; it tolerates cool temps but not sustained damp.

Yes, the plants produce a noticeable citrus-pine aroma during late flowering so use carbon filters or other odour management where discretion is required.
