The cooling fan's air passes through the area needing to be cooled. Has just enough power for 1-2 small to medium sized plants from seed to harvest. Works really well in my 3'x6' greenhouse.

Thumbs up. The timer is a must have. Fully adjustable brightness is great.

The light has a timer which is beyond nice. I program the light to be on for 12 hours at night and my plants have never been happier. All plants need sleep time, so it's best to use it during daylight hours.

These were purchased in mid september and both are degraded. They flip and move around so easily. It is very frustrating.
