Choosing Grow Lights for Seed Starting

Reptile lights (compact fluorescent) may work if 40W. But standard 48-inch, 40W T12 shop lights are cheaper and proven.

Setup Example

• 4-foot wide shelving, 5 shelves.
• One 4-foot, 2-bulb fixture per shelf (~$11 at Walmart).
• Each shelf holds four 10x20 trays.
• 16 trays total; germinates thousands of seedlings.

40W per bulb minimum. Suspend 6–8 inches above trays.
