This 3 week old flower is on a 2 1/2 month old plant which has had nothing but fluorescent light in a closet. It's in the cheapest soil I could find, in an empty 5 liter water container with holes cut in the bottom. I threw a few plant food spikes in the container, but I'm honestly not sure what they were because my French is not great, and the label was in French. I started using a teensy bit of plant food after the flowering began, but I don't want to overdo it. (I can't read that label either). I really should make more of an effort to learn French. Nonetheless, I think this photo says it all. Growing grass doesn't have to be complicated or expensive.
