Optic Foliar SWITCH - 4L

Foliar Spray to Support Early Flower Initiation - 4L

Stress during the transition to flowering can delay blossom set and slow a crop down. Optic Foliar SWITCH is a foliar spray applied in early flowering that targets those stress factors, so plants can start forming flower sites on time. The distributor states it causes no loss in growth, quality or yield.

The 4L bottle suits growers who want to treat several plants or a full room across a repeat application series. A single bottle covers multiple spray sessions, since the schedule calls for 2-3 applications.

Key Features & Benefits

• Early-flower timing — use in the first weeks of flowering to support earlier bloom triggering with tighter nodes.
• Ready to mix with Transport — add Optic Foliar Transport directly to the product; no water dilution is needed.
• Flexible schedule — repeat 2-3 times, 10 days apart, anytime from early to late flower.
• Foliar mist application — wet the leaves without runoff instead of drenching the root zone.

Who Should Use Optic Foliar SWITCH

Indoor and commercial growers who want to support the move from vegetative growth into flowering, and home gardeners running a foliar program, can use this product.
