The couscous that is sold in most Western supermarkets has been pre-steamed and dried; the package directions usually instruct to add 1.5 measures of boiling water or stock and butter to each measure of couscous and to cover tightly for 5 minutes.he couscous that is sold in most Western supermarkets has been pre-steamed and dried; the package directions usually instruct to add 1.5 measures of boiling water or stock and butter to each measure of couscous and to cover tightly for 5 minutes.

You can put a clamp lamp that takes a compact flourescent bulb over a small tank and grow a lot of plants pretty successfully that way. Not quite as attractive, but they do work quite well.
Diffused LED bulbs. Dimmable Globe LED bulbs. Designed for bathroom vanities or anywhere a globe bulb is required, these bulbs produce light equivalent to a 40-watt incandescent bulb, yet only consume 10 watts of power. Dimmable from 100% to 10%, these bulbs have a 200 degree beam angle to cast light in a wide area.
