 Since light is the most important factor affecting indoor gardens, a quality Digital Light Meter is essential for accurately determining if your crop is receiving what it needs for healthy growth. Includes a life-time battery, lighting recommendations and a convenient carrying case.
Unique Features:
• Measures grow lights or sunlight
• Measures up to 5000 foot-candles
• 3 scales for precise readings
• Convenient hand-held remote sensor
• Lifetime silicon cell
Grower's Tip:
For maximum growing efficiency, we recommend checking your MH and HPS bulbs periodically with a Light Meter. As bulbs age, their intensity drops, lumen output decreases and foot-candle (a measurement of illumination) readings weaken. High Intensity Discharge (HID) bulbs should be replaced every 6 to 12 months, regardless of the number of hours they're rated for. |
