I have a pop up tent in my yard and this is similar as far as stability
I have weights on my pop up tent's four legs, plus they are staked. I think it would be smart to include some sort of weights for this greenhouse as well. The greenhouse itself is large enough for seed starting in spring, though I also had to add some wood plant stands because this does not come with any shelving. I've not had any problems with wind as I have it in a protected location in my yard, but definitely, if I was worried about winds, I'd use both the stakes/tie-downs included AND sand weights just to make sure I'd done my best to keep it secure. Now, the other thing - shelving - they could have included some shelving, but my thought is that it would have been cheap and too lightweight so I'm good with having to add some of my own which is sturdier and higher quality. Still, for the price it is a good-sized greenhouse that will be perfect for spring time plant starting.
