Strong enough to hold all heavy plant cuttings on top of it. We ourselves tested it 26 lbs+ weight on it for 7+ days so far by today on April 11th, 2019. Nothing happens. There is <b>no ''falls-out''</b> or <b>no ''water spraying'' outside grow chamber,</b> as long as users put the top lid on right (it is easy, believe me!)</p><p>We will increase the thickness of top lid when next mass production, thank you so much for trusting us!</p>
