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.

It's quick and easy to setup and provides lots of light. Highly recommended for any household and plant lover. Great customer service.

It covers a large area and plants don't get over shadowed by the larger neighbor. Seems to be working well on my seedlings for the garden. My succulent plants are thriving.

My only complaint is the the longest it will stay on is 12 hrs. I enjoy that the product comes with automatic timers for the light and different color settings.
