Optic Foliar Switch is a targeted flower-initiation foliar spray formulated to help plants transition from vegetative growth into bloom more quickly, evenly, and with enhanced structural control. By stimulating the plant’s natural ethylene signalling pathways at the onset of flowering, Switch minimises excessive stretching, tightens internode spacing, and promotes a denser, more manageable canopy. This structural optimisation results in more uniform bud sites, setting the stage for a heavier, higher-quality harvest.

Beyond its bloom-accelerating properties, Switch is valued for its ability to reduce the risk of hermaphroditic development under environmental stress, preserving crop integrity and yield potential. The non-toxic, residue-free formula is designed to be safe for early flower application, leaving no impact on the plant’s aroma, flavour, or visual appeal, and integrates seamlessly into professional foliar routines.

Fast-track bloom, control plant structure, and protect flower quality from day one.
