Customer Reviews
Good light, fast shipping
I bought an FC Series LED Grow Light. It got to me in about 4 days, which was quicker than I expected. The light itself works well for my plants. Very happy with the purchase.
Tent kit was what I needed
I decided to get a Grow Tent Kit last month. I'm just starting out, so I needed something easy. It came pretty fast, like a week to get to me in Texas. Everything was there and putting it together wasn't too bad. The fan's a little louder than I thought it'd be, but it does the job. Overall, it was a solid buy for a beginner like me.

Hey, thinking about grabbing an FC-E 4800. Anyone know how Mars Hydro shipping usually runs to, say, California? Need it kinda quick for a new setup.
