To increase the percentage of double flowers, use the following procedure. 1. Triple sow a 288-plug tray with Stock Iron seed. 2. 8 days after sowing remove the last to germinate seedling with a tweezers. If only two seedlings germinate wait until the next step. 3. Around day 9-10 allow the soil to dry slightly. This will make the final selection easier. Make the final selection around day 14 before the emergence of the first true leaves. – The double-flowered seedlings are more vigorous and grow more rapidly. – Double-flowered seedlings have larger and longer cotyledons with a more irregular/elliptical shape and a lighter green color. – Single-flowered seedlings will be shorter, with smaller cotyledons with a more round/oval shape and darker green color.
