Most gardeners sow fast-growing annuals, such as sunflowers, bachelor buttons, calendulas, zinnias and nasturtiums right into the garden. I agree that it's not worth the trouble to grow these seeds indoors for just three to four weeks, and also run the risk of transplant shock.
In the smaller area, grow seedling or clones (see 18.5) for two to six weeks under fluorescent set on a constant light. In the larger section, keep HPS lamp(s) on a 12-hour light cycle for flowering. Move larger seedlings under the HPS lamp(s) for about 9 to 15 weeks to initiate and complete flowering.
