Use Grow Lights to Grow Citrus Fruit Indoors
November 15, 2018
Grow citrus indoors with 12 to 16 hours of supplemental light. You can get good growth and vigor from citrus using MH/CMH, CFL, or intense HO T5 lamps, but you’ll need a full-size grow lamp.
You can also place citrus plants inside grow tents with HID lamps for best production. If you have very bright south-facing windows, you may be able to combine that natural light with a few spotlight CFLs to keep a group of citrus happy in your living room.
