Grow Light for Echinopsis: Easter Lily Cactus Indoors
A grow light for echinopsis helps this sun loving cactus bloom indoors. NC State Extension says echinopsis enjoys full sun but benefits from some afternoon shade in very hot climates. Its large, funnel shaped flowers open in the late evening in spring or summer.
The short answer
Give echinopsis full sun or a bright grow light. Set the light 6 to 12 inches from the plant tips on an adjustable fixture and run it 14 to 16 hours a day. Use a cactus mix and water once it dries. Good light helps the large flowers form.
How much light does echinopsis need?
NC State lists full sun for echinopsis, with some afternoon shade in very hot places. UF/IFAS Gardening Solutions finds that cacti do well in a sunny indoor spot, growing a few inches a year at most. Water left in the saucer leads to root rot. See grow lights for cannabis for light options.
Which grow light suits echinopsis?
Minnesota Extension stresses that cacti and succulents need a lot of light. Artificial light makes up the difference. The Extension suggests cool white fluorescent tubes or daylight mixed with natural white, 6 to 12 inches over the plants, lit 14 to 16 hours daily. University of Missouri Extension says most plants do well with tips 6 to 12 inches from the light. Intensity falls fast with distance, so pick an adjustable fixture. Missouri notes high light plants are harder to grow under home lights since they need at least 1,000 foot candles. Read led light distance cannabis for distance and grow light timers for timers.
How do you tell if echinopsis has the right light?
Blooms are the surest sign. NC State says the blooms are large and showy, 3 to 6 inches across, white or pink in most species. Minnesota Extension says good light, dry soil and cool nights help cacti bloom indoors. If a mature plant doesn’t flower, add light.
