Customer Reviews
Decent light, minor shipping delay
I purchased the FC 3000 Samsung LM301B LED. The light itself is bright and seems to be really good quality; my seedlings are thriving under it. Shipping took 8 days to reach me in Adelaide, which was a bit longer than I hoped, but it did arrive safely. Everything was well-packaged. The instructions could have been a little clearer for assembly, but I figured it out. Good value overall.
So happy with my tent!
Got the 3x3 Grow Tent and I just love it! It popped right up, zipper feels strong, and it's completely light-tight inside. My plants are going to be so happy. I'm definitely coming back for an Inline Duct Fan soon. Mars Hydro rocks!
Good light, solid purchase
I ordered the FC-E4800 LED Grow Light. It arrived in about a week, shipped from within Australia. Packaging was discreet, which I appreciated. Setup was straightforward, no issues there. The light itself feels well-built, and it's performing as expected in my 4x4 tent. I had a quick question about hanging height, and their support got back to me pretty fast, within a day. Overall, a smooth purchase and the product does what it says.

Hey, thinking about grabbing a grow light, maybe an FC-E6500. How long does shipping usually take to somewhere like Chicago?
