Crop Reactions

・Young plant grown under F-CLEAN

became more robust, more resistant

to sudden climate change.

・As a result, time consuming work of

getting the plants familiarized to Sun light

has been omitted.

【Use’sTestimonials 】F-CLEAN provides far better ultraviolet

transmission than glass. That has prevented

the abnormally elongated seedlings that result

from insufficient light and from an unbalanced

light spectrum. Our seedlings are compact and

robust. They stand up to automated planting in

the field. F-CLEAN has given us more-stable

supply capacity, as well as lowering our

operating costs.
