in wintertime i´m gonna use an ordinary plant-lamp with a "daylight"
pear. it has 6400 and should fit for plants. I´ve also read that "cold
white" fit´s for plants.
But i got another question: How long should i put my cacti under the
light? Are 12 hours enough or would i get some better scores by
lighten them longer, for example 14 or 16 hours?
