Weekend Gardener

When growing under artificial light – the light intensity factor may be more important than type of light or even the number of hours of light per day. It is as important as daylight of adequate intensity in window gardening. The average intensity of artificial light for most types of plants – measured at or near the plants, not above them or to one side – should be the rough equivalent of daylight in midmorning on a bright summer day. Semi-shade loving plants will accept less intensity; full-flowering sun-lovers will need more.
