What Optic Foliar Switch Does in Early Bloom
Flower set is a stress problem. Heat, a light change or a hard defoliation early in bloom delays the blossom set, and the plant loses days it does not have. This is sprayed on day 7 and again on day 17 of the bloom cycle, or at the first sign of flower stress. It is a foliar, not a feed.
Mixing and Timing This Optic Foliar Spray
Three rules, and none of them are optional. First, do not dilute it with water. The bottle is ready to use. What you add is Optic Foliar Transport at 10 mL per litre, or 2 teaspoons per quart. Second, do not adjust the pH. Third, spray within about 15 minutes of mixing and discard what is left, because the mixed solution does not keep. Application itself is straightforward. Mist to wet the leaf without runoff, in a room between 60 and 75 F. It can be sprayed with the lights on, which is the point of the Transport carrier and the reason this line exists. Repeat two to three times at roughly ten day intervals.
Key Features
- Day 7 and day 17 of bloom: Or at the first sign of flower stress. Repeat every ten days or so.
- Sprayed with the lights on: No shutdown, and no waiting for a dark period to treat a room.
- Do not dilute with water: It arrives ready to use. Transport at 10 mL per litre is the only addition.
- Do not adjust the pH: The solution is built to work as mixed, so leave it where it lands.
- Spray within 15 minutes: Mixed solution does not keep. Mix what you will use and discard the rest.
- Mist, do not drench: Wet the leaf without runoff, in a room between 60 and 75 F.
