Long photoperiods using high light intensities from 10,000 to 20,000 lumens/m² increase dry matter production, and increasing the photoperiod from 15 to 24 hours may double dry matter growth (Pollard and Logan 1976, Carlson 1979).[2][3]. Hollyhocks are considered a biennial, producing clumps of leaves the first year and then tall flower stalks the next year. Why does the shell get stuck to the seedling?

Somewhat paradoxically, however, Eis (1967a)[5] observed that on both mineral and litter seedbeds, seedling mortality was greater in moist habitats (alluvium and Aralia–Dryopteris) than in dry habitats (Cornus–Moss). Keep lights 3-6” from tomato tops. Seedlings have a little reserve to help establish themselves in their growing environment.
