Sophora

Use constant gentle airflow with intake and exhaust fans, and open vents on warmer days to keep humidity below 60 per cent; this is essential for UK greenhouse cannabis growing.

Start with a mild vegetative feed and increase potassium and phosphorus during bloom while monitoring EC to avoid nutrient burn.

Perform light defoliation after the third week of flowering to improve light penetration, then avoid heavy pruning late in bloom.

Reduce canopy density, control humidity, pick away affected leaves early and remove any standing water around the greenhouse.

Yes, in a sheltered, sunny spot with good airflow; expect higher mould risk so pick a site protected from prevailing winds and rain.

Spider mites, thrips and fungus gnats are common; use sticky traps, biological controls and keep foliage dry to minimise outbreaks.

Dry slowly to 10–12 per cent moisture then cure in jars for at least two to four weeks, burping regularly to avoid ammonia development.

Yes, SCROG or LST increases even light distribution and generally improves greenhouse yields for Sophora.

CO2 helps in tightly sealed, well-lit greenhouses but is unnecessary in ventilated setups and can increase mould risk if humidity rises.

Harvest when trichomes are mainly cloudy with some amber for balanced effects, and check buds for signs of rot before bringing them in.
