I would like to grow some Red Robin tomato plants indoors this winter,
but I'm having trouble. My first attempt failed, as the plants became
a rich dark green (seemingly too dark), then their leaves began to turn
pale and wither.

I've heard that Red Robins are an easy plant to grow indoors? Can
anyone tell me how to do it? I need some user-friendly advice and
suggestions because I'm obviously doing something wrong.

Any replies appreciated.
