Hello all!

I have a horticulture-related question that I swear I learned in hort class, but I can't for the life of me remember the answer.

Q: I know that fluorescent lights are considered "blue" lights, and incandescent lights are considered "red" lights. Which type of light stimulates vegetative growth, and which type stimulates flowering?

Q: I was also taught that for proper plant growth, both types of light wavelengths are necessary. Do you believe this is particularly important for orchids as well? Should I be supplementing "red" light?

Thanks!
