Mars Hydro- Pro II- Cree LED Grow Lights
Light your 4'x4' or 5'x5' Grow Room
Mars Hydro Pro II LED Grow Lights are ideal for 4'x4' or 5'x5' grow tents. Using USA built Cree LED gives incredible power at low temperatures. More than double the PAR per watt of a traditional HPS or HID light.
Choose between Grow and Bloom cycles at the flip of a convenient switch. Or you can have both cycles on at the same time- which is what we recommend.
WARNING- DO NOT use the Bloom setting without the Veg mode on as well- the fan doesn't work in Bloom alone. Burnout might occur
- 1-year full warranty (shipping fee and replaced parts are free). From 1 to 2 years, you’ll be responsible for shipping charges and replaced parts are free. From 2 to 3 years, you’ll be responsible for shipping charges and handling fee.
