Customer Reviews
Consistent quality, fast delivery
I ordered more potting soil and some seed starting trays. This is my third time ordering from Greenhouse Warehouse. Just like before, everything arrived well-packed and on time. The quality is always good, which is why I keep coming back for my gardening supplies.
Good value on grow lights
I was looking for some new grow lights and found their LED grow lights on sale. The price was pretty competitive, especially since I got free shipping which really helped with the total cost. Took 7 days to reach me in California, which was fine. The lights themselves seem well-made and are working great for my indoor plants. Felt like a solid purchase for the money I spent.

Share tips, ask questions & help fellow shoppers save more
Hey has anyone used the clearance section for polycarbonate panels? Wondering if it's worth it or if they're all super dinged up.
Does Greenhouse Megastore actually ship greenhouses pretty quickly? I'm in Arizona and trying to get one set up before it gets too hot.
