Aims: To evaluate the effects of high intensity LED light with different wavelengths (red, blue, green and magenta filter) in physiology and absorption spectrum of lettuce (Lactuca sativa L.) and broccoli (Brassica oleracea L.) seedlings, with exposure times of 12 hours, in order to improve the growth of vegetables. Study Design: Four treatments of light (red, blue, green, magenta filter) and one control (white light). The experimental design was completely randomized, with two replications of 14 seedlings per experimental unit.
