Hydrobest 300W LED Grow Light Full Spectrum + Grow Tent + 4" Inline Fan Carbon Air Filter Ducting Combo for Hydroponic Indoor Plants Growing (32''x32''x63'' grow tent kit)

Some thing loose inside, rattle. I was concerned so I opened it and found 2 extra small metal screws inside.I triple checked to see if I could find a place where they might go. In the end I just figured that they wereboth extra. My conclusion is that this usually happens to someone that has a cluttered, dirty or chaoticworkbench or desk, with too many item just laying around. So please keep your desk clean.The light has been running daily for 5 weeks now and seems to be doing fine.4 stars is justified I think.Respectfully.

Let me start by saying this is a review for the 1800w cob. I have only used this cob 1800w light one day but am returning it due to the fact it runs crazy hot, close to the same heat as my hps 600w but my hps might actually run cooler when vented correctly, and this light is not much, if at all brighter then my 600w hps. also its about 4x heavier. I don't see any advantages in using this light other then maybe saving a 100w on power, but it would probably equal out due to the extra cooling the light would need. I am going to stick to my hps and non-cob led's for now.

The price is cheap, so it was what I expected. It was weaker then expected, but I just put it closer. I have a smaller light that has 4 COB that seems to be way brighter, and lights my whole closet up if I wanted. I would rather have that for cheaper, but I want to see how this spectrum works out in the end. I like he spectrum, and the light. I bought it planning to swap out the weak COB units. I may just leave it alone. It is perfect for the corner of my closet. I use it for a small area, so it is nice. It would not be good for my whole closet. It is nice, but you can get more out of a smaller cheaper light if you get the right one. My light for $140 was burning my plants it was so strong. I have to be careful with it. This light is my most expensive, biggest, and weakest lol. It has tough competition though. I know these lights, and got this for a specific reason. It is great depending on what you need it for. You can save $60 to get a brighter one with more of a white color though. It has other colors, but the white drowns out all the other lights. I suggest this light if you know what you are getting. it looks like a lot more then it is. It is like a fast looking mustang with a tiny motor. It will still get you to where you want to go, but take a little longer to get there lol.

The seedlings seem to love the light and are growing well. Unfortunately, after only five days of use, the light has malfunctioned. The two rows of LED's on each end are now blinking off and on at a rapid pace. I'm broken hearted, but back they go.

so far so good def want to get two more for a 1.5meter by 0.5meter to really bring on the sunshinethis will def help pack on yield for fruits or flowers..recommend for indoor horticulture only reason have not gave it a 5 is don't know the durability and life span of wear and tear..review few months down road could add one more star or loose one..we will see, worth the buy...

Was worried at first been a few weeks still going strong so id recommend i have it paired with a more expensive 300w and i can see not much of a difference but this light is very heavy in the red specturm but not bad for bloom

The lights do their job! I grow some big plants with them!! Check out nicknikkigrow NNG on YouTube and see for yourself! Honestly for the price you can not beat these lights! My issues are lenses need to be 120 degree lenses and heat sink needs to be bigger and bigger faster fans!! I rather deal with the noise than my grow room be 95 degrees!

Light seems to be doing a great job. It is much better than the cheap LED light I was using. This is by far the best light I've seen for the money. It does run a bit warm though so you will have to have good air flow in a small grow area.
