Today's work was to empty the container I filled with water yesterday. My plan was to save it for the flowers, but the 'bath tub' prooved irresistible for the younger generation and when I found the cans for flowerwater already filled I gave in and fetched a siphon.
To get you something to read I tracked down a good page about grow light on the net. Little Greenhouse sell greenhouses (surprise) and have put some facts on their website. It's a clear and consise overview.
If you want added light and can't afford the lamps described you can use ordinary cold-white fluorescent tubes as bright as possible. They work almost as well and are far cheaper. I use them myself.
