Important notes
flowering: Once basil flowers it bolts and the leaves turn bitter. Pinch off flower buds regularly to keep the flavour. ↗
Licht
Very bright: 6+ hours of sun or 14–16 h of grow light. Too little light makes plants leggy and low in flavour.
Water geven
Keep evenly moist, never bone-dry, but avoid waterlogging. In soil/coco water as the surface dries; in hydro it is fed continuously.
Temperatuur
Keep warm: 20–26 °C. Below 12 °C it suffers cold damage (black blotches).
Luchtvochtigheid
50–65 %. Still, humid air encourages downy mildew.
