Frequently Asked Questions

Q: How many plants can fit under a 4' x 4' (16 sq. ft.) area?

A: The amount of plants that can fit in a 4' x 4' area is completely dependent on the size of the plants and the size of the pots used. A five gallon pot is about 12" in diameter on the bottom, which means you may have up to 16 pots in a 4' x 4' area.

Q: Can a lower wattage lamp be used with a higher wattage iPower ballast, and vice-versa?

A: Different mismatched wattage lamp and ballast per light fixture may cause premature ballast and/or lamp failure, and is not covered under warranty. Please use the same paired wattage lamp and ballast per light fixture; the dimming feature is designed for the purpose of a lowering lamp output when needed.
