The light is approx 2in above talest plant and about 4 in above top of shortest. The light is 4 ft long and plants are in line right below. I was thinking about using a 20000K light, same size (260W compact flou). How do actinic lights (420 nanometers wavelength) work on these guys??
smacky Reviewed by smacky on . help with lighting I am using a coralife 48in 6700K 4X65watt compact fluorescent fixture over 8 plants. This is my first indoor grow but I have grown many outdoors and at this age they were alot taller. The plants are 8 weks old and are about 4 to 7in tall, they are the densest plants I have ever grown, but they are short, the stems are outrageously thick. Why so short? Is it my light? I am using a hydro setup with GH nutes, they are on an 20/4 light cycle, and have CO2 supplementation. I'd love to have the Rating: 5
