Guava Cooler

Keep relative humidity around 40–50% during flowering and lower in late bloom to prevent mould, especially in a greenhouse setting.

Use good cross-ventilation, an extractor fan and periodic passive intake to move moist air out and reduce condensation during cool nights.

Low-stress training and topping encourage an even canopy and improve light penetration, which reduces hidden wet spots and lowers mould risk.

Moderate nutrients with a slightly higher phosphorus and potassium ratio in bloom supports dense bud formation without excessive vegetative growth.

Harvest when trichomes show mostly cloudy with some ambers for a balanced effect and avoid waiting too long to prevent overripening in damp climates.

Dry in a well-ventilated, temperature-controlled space with dehumidification if needed, then cure in jars while monitoring for any moisture spikes.

Watch for powdery mildew, botrytis and spider mites, and respond early with improved airflow, targeted biocontrols or approved treatments.

Yes, greenhouse cannabis cultivation can be ideal if you maintain ventilation, control humidity and protect plants from driving rain and salt spray.

Supplemental lighting through late spring and summer improves bud density and ripening, particularly under cloudy conditions common here.

Feminised seeds simplify the grow by ensuring female plants, reducing the need to identify and remove males mid-cycle.
