Chrysanthemum is a short day plant that needs an efficient blackout screen with minimal light transmission. And we’ve got just the product for you: it not only keeps your chrysanthemums in the dark, but shaves as much as 70% off your heating costs.
This type of flower responds well to light intensities as high as 800 W/m2. Beyond that, shading should be used to counteract stress and leaf burning.
