SDR Organic Spinach

SDR (Short Day length Requirement) is a priming for Spinach seeds that aligns the development of female and male lines by causing the Spinach plant to bolt earlier and more uniformly. Speed of bolting and flowering can be improved by more than a week. SDR also results in more side shoots which gives increased seed production, fewer stress symptoms before and after bolting and fewer inbred seeds with hybrid seed production. The organic SDR version is suited for the organic market as only organic regulated substances are used.
