Question: Do differently coloured light rays intensities affect a plants colour growth flavour and if so, do you think they would sell?

That’s a great question! Yes, certainly there’s a difference in growth with the amount of light generally, if you think about the type of big juicy tomatoes you can grow in bright sunny places compared to the little ones that don’t get enough light. Flavour would be affected by that too. Now whether the colour of the light would also matter I don’t know but that could be a really great experiment! Perhaps you might do something on it for the Young scientist competition?!? I’ll be on the look out for that!!
