Yep. There are very few true Annuals.
Woofie - I use flourescent lights. Have not tried any of the LEDs.
Many - probably - most things you grow as Annuals - are actully Perennials - just not in your zone. My attitude is Zones be dam***. Pentas? Angelonia? Calibrachoa? Lantana? And on and on and on come in and grow next year. I hate wasting money on "Annuals".
