all it is, is a tube with super reflective sides. so what it will do is reflect every thing from the sun. all the gama, UV rays and stuff. so if the light bulbs we use mimic the sun then this woild be perfect. I have one tank at the moment beside the window and it recieves all the light that the day gives. i use no light and i have to cut my plants once every two weeks. so i think it will be ok.marks69 said:those tubes work well in a kitchen, but around here all the lens's are white, don't know if it would help plants or not.
