Optic Foliar SWITCH - 1 L

Foliar Support for Early Flower Initiation - 1 L Bottle

Stress during the transition into flowering can slow the formation of flower sites. This foliar spray is designed to address those stress factors so plants start flowering on schedule. You apply it as a light mist, so it fits into an existing feeding routine without a new system.

The 1 L bottle suits small to mid-size indoor gardens and growers trialling a foliar program for the first time. Larger operations can order multiple bottles to cover more plants across repeated applications.

Key Features & Benefits

• Early flowering use — applied in the first 2 weeks of flowering to support the start of bloom.
• Foliar application — mist leaves directly, with no drenching.
• Mixes with Optic Foliar Transport — add 10 ml directly to the 1 L bottle and shake.
• Repeatable schedule — apply 2-3 times, 10 days apart.
• Compact 1 L bottle — easy to store and handle.

Who Should Use Optic Foliar SWITCH

Growers who want to support the transition from vegetative growth to flowering in indoor or commercial cultivation, and who are comfortable applying a foliar spray at controlled temperatures.
