Growing a Houseplant in a Windowless Bathroom with Grow Lights

Can a Bathroom Work?

A windowless bathroom can house a plant if you provide adequate artificial light. Humidity is a plus for many tropicals.

Grow Light Setup

• Fixture: Fluorescent shop light with 2–4 T5 or T8 tubes (full spectrum, 6500K).
• Distance: 6–12 inches above the plant canopy.
• Duration: 16 hours on, 8 hours off (use a timer).
• Companions: African violets thrive under the same conditions.

Watering Caution

High humidity slows soil drying. Water only when the top inch feels dry. Ensure the pot drains freely—never let it sit in water.

Plant Selection

Choose low-light tolerant, humidity-loving plants: Aglaonema, Spathiphyllum (peace lily), Philodendron, Pothos, Zamioculcas (ZZ plant), ferns.
