Xavier's new Drosera capensis (from Predatory Plants) has no dew despite "plenty of UVA light" and water in a terrarium in Slidell, LA (freezing outdoors).
"UVA light" tells nothing about intensity. Sundews are the final judge—move lights closer (8–12″) and give it a month. Shipping/repotting trauma may mean current leaves never produce dew; judge by new growth.
Without intense artificial light (e.g., 1000W HPS), tropical sundews naturally produce less dew in winter. Accept lower dew or invest in serious lighting.
Terrariums often reduce light further; consider moving to a bright windowsill + supplemental fluorescent tubes.
