Wouldn't it be pointless to use green frequency LEDs? (wouldn't the plant reflect green light?) I don't know which wavelengths would be best used by the plant. I was thinking about doing something where I'd place a couple clones under each frequency and see which one does the best?

As far as I'm aware there are green, red, yellow, blue, orange. I'm sure there are more?

Would depriving the plant of a wavelength of light have any adverse effects?

I tried searching around the forum I couldn't find too much info. I'm trying to design my first grow box. I cant decide if I should go with LED or fluorescent for my seedling chamber. Electricity where I am is about 0.15$/KWH. Doing this as effectively as possible is a primary concern. It seemed that LEDs are the best way to go about that.
