1. What is the size of the Grow Ring™?
STAKE: 10 Inches in length
RING: 3.5 Inches in diameter
USB WIRE: 32 Inches (approx 3ft) in length
2. How many stakes come with each ring?
Answer: Each number of rings includes the appropriate number of stakes with it.
1 head = 1 stake
2 head = 2 stakes
3 head = 3 stakes
So if you buy the 3-head Ring, you will receive 3 stakes with it.
**Rings are all connected to a single wire on multi-ring units. If rings are going to be used in separate locations, please purchase multiple single rings**
3. How close do the rings need to be to plants?
Answer: Artificial lighting must be very close to plants to be effective. As the rays of light move away from the plant, they dim significantly. Indoor plants grow best when they are within 6 inches or so of the Grow Ring™.
