The problem in cultivating Eucheuma cottonii is the procurement of seeds and techniques currently developed through tissue culture. The limiting factor in this technique is the use of optimal light for the growth of the seaweed. The aims of study was to optimize the wavelength of light on the growth of E cottonii propagules. The research method is laboratory experimental with the treatment of different wavelengths of light: red light wavelength (λ = 633.8 nm), green (λ = 515.8 nm), blue (λ = 455.7 nm), combined light on the lamp LED (λ = 456.6 nm, 515.8 nm and 632.9 nm), and fluorescent light in TL lamps (λ = 407 nm, 443 nm, 557 nm and 592 nm).
