They aren’t thick plastic but they are a good design and great for plants with shorter roots. I live in Georgia and I had my bell peppers in a covered raised bed but since fall/winter is odd here where one day it will go below freezing at night then the next week 80 during the day and well above freezing I just transplanted them into this so they can go in the portable greenhouse. I now have three of these set up with six tiers each and planted my lettuces in the additional. They have a hole running down the middle so I have the green garden stakes you can buy at the garden center going down the middle to give them some additional support. I didn’t use the chain that was provided. It seemed more sturdy to use a pole. They are pretty stable on a flat level surface if you had them in your home though. I don’t love the water doesn’t flow down through the tiers from the top but you could poke small holes in in the bottom so it does. It has a tray on the bottom that can catch excess water. I do like that they provide the plastic barrier so excess water goes under that. Unless the roots are long enough your plants can’t take advantage of it though. So, the only thing I would do differently is place pieces of rope that hang in the water and go up into the dirt so it pulls water up. My lettuce seedlings I have to water every day because I didn’t think about that until I finished planting them. The nice thing is that, yes, they aren’t super deep but as you can see from the photo it’s one big pot so the plants roots have room to spread. I will continue to use these as long as they hold up. By planting vertically it’s allowing me to save space and I can grow more since I am limited to the greenhouse in the winter.
