How to Grow a Peace Lily Under Fluorescent Lighting

Calculate how much fluorescent lighting your peace lily will need based upon the plant's size. Plants with low level light needs, like this one, require 10 to 15 watts of fluorescent light per foot of growing space. A small plant with 8 cubic inches of growing space only requires 7 watts of fluorescent light, while a larger plant with 2 cubic feet of growth area needs 20 watts at minimum.

Set your peace lily under a fluorescent plant light so the tallest shoots hang 6 to 12 inches below the light.

Water the soil until it feels moist to the touch, but not soggy. Allow the dirt to dry out between watering.

Maintain a constant growing environment of 68 to 85 degrees Fahrenheit in the day and 58 to 75 degrees Fahrenheit at night. This plant dislikes both hot and cold conditions.

Fertilize your peace lily every two to three months using a water soluble 20-20-20 fertilizer. Dilute the right amount of fertilizer with liquid, based on the size of your plant, and pour fertilizer over the plant to disperse.

Wipe dust from peace lily leaves using a damp cloth. Cut off dead leaves at this time to maintain an attractive plant. Periodically inspect your plant for pests, and treat with insecticidal soap if necessary.

Increase the wattage as your plant grows and requires more artificial light. Use the same formula to determine the new dose as you did initially.
