I purchased this stand three weeks ago, setting it up hanging a 150W Vevor grow light from the stand. The weight of the light is roughly 10 pounds. This is easy to adjust the height. I have mine at 8 feet and it is still very stable. I did not try hanging an Exhale 365 CO2 bag. Mainly because the bag says 4.5 lbs on the ad but feels like 10 lbs. Overall this is well built and very easy to assemble. 5 Stars

High Quality, good product. Well built

This grow light rack is exactly what I needed. It’s easy to assemble and take apart, it only takes a few minutes. It can get tall enough to use for any plant. I have 3 lights on mine with no problems. Great product.

Would be good but top bar is too flexible and the connections are insecure. Can't actually use it. Bends too much, not trustable.

We bought two of these light stands to expand our capacity over the winter for all our outdoor plants. It was so easy to setup and came in a very nice travel case which was not expected. So far it is working great and as you can see by the image is keeping our plants healthy while they are being sheltered in our detached garage over the winter. Good price and good quality product!
