Abstract
Abstract Continuous lighting with Lucalox lamps at 58W/m 2 supplementing natural daylight for 1 to 4 weeks after transplanting increased plant height, root length and fresh weight of Petunia hybrida Hort cultivar White Cascade, Tagetes erectra L. cultivar Moonshot, and Zinnia elegan cultivar Peter Pan Pink. Differences became larger between lighted and unlighted treatments as the lighting period increased. Plants lighted for 4 weeks after transplanting flowered earlier (9 to 23 days), were slightly shorter, and had larger top fresh weight than those unlighted, Impatiens sultanii cultivar Scarlet Elfin responded less than the other species.
