Optic Foliar SWITCH – Flower Initiation & Stress Management Foliar Spray
Optic Foliar SWITCH is a specialised foliar treatment designed to support flower initiation and help plants manage key stress factors during the transition from vegetative growth into flowering.
Applied during the first two weeks of the flowering stage, SWITCH is formulated to encourage an earlier transition into bloom while promoting tighter internodal spacing and strong flower-site development. By helping plants through this important transition period, growers can establish a more uniform flowering canopy and maximise the plant’s productive potential.
One of the key applications of this product is helping prevent the formation of unwanted male flower parts caused by environmental and plant stress. It may also help address male flower structures that have already begun developing, reducing the risk of unwanted pollination and seed formation.
SWITCH is formulated using ingredients described by Optic Foliar as natural, non-toxic and non-carcinogenic, and is designed to leave no unwanted residue when used according to the manufacturer’s directions.
For best results, SWITCH is designed to be used with Optic Foliar Transport, which assists with even application and rapid foliar uptake.
Directions for Use
Mix 10ml of Optic Foliar Transport with 1 litre of Optic Foliar SWITCH. Shake the solution thoroughly and apply within 15 minutes of mixing. Follow the manufacturer’s complete application instructions and recommended flowering schedule.
For a complete foliar program, SWITCH can also be incorporated alongside Optic Foliar OVERGROW, which is designed to support plant performance throughout vegetative growth and flowering.
This product is ideal for experienced indoor and hydroponic growers looking for greater control during the critical transition into flowering.
It’s a practical addition to a controlled growing program where consistency, careful environmental management and strong plant development are priorities throughout the important transition from vegetative growth into flowering. Go for it!
