I am loving these for seed starting and transplanting my seedlings into bigger containers. They are very sturdy. They are a little harder to fill than a pot but not too bad. I'll update for how they do once they are transplanted into the gardenUpdate Sept. 2020- These things are super durable. I actually reused a lot of my old bags a second season with new seedlings. The roots grow right through them and so for things like corn that dislikes being transplanted (we live in a cold climate and have to start them inside), they did very well and there were no root bound plants. They probably eventually break down but after two summers I'm still finding completes sturdy bags in my garden soil. Luckily they don't jam up my tiller but I do have to walk through after tilling and pick up all the old bags. I like the smallest size the best for seed starting. The bags hold A LOT of dirt. I also find it a lot more time consuming to fill the bags because you have to hold them open while filling and can't fill more than one at a time, unlike with plastic pots or starter trays. But I love how these bags perform so I'm trying to come up with a tool to hold open multiple bags at a time while I fill them.
