This starter kit is good to start seedlings. It's built quite strong. But, when it's time to transplant a seedling to the garden or pot, it's hard to remove the individual seedlings from the cells. The strength of this product isn't flexible enough or as forgiving to cut the cell away from the tray or push the transplant from the bottom of the individual and keep the root ball intact. If the individual cells weren't as thick as they are, then the product would be a little bit easier and pliable to work with at the time of transplanting
