It was just uploaded by the Youtuber Midwest Gardener, another video “Tiny Terrarium Success – Baby Golden Barrel Cactus Seedling.”.
As pubished in the youtube video by Midwest Gardener: “When I posted the video about unboxing and planting the tiny terrarium, I said that I would update if I got anything to grow. Here we are, a little more than a month later, and I have a tiny cactus growing in the tiny terrarium. Unfortunately, if it keeps growing, it will not be able to stay in it’s current container very long. The cactus seeds that came with the terrarium are those of a Golden Barrel Cactus, which gets over a couple of feet tall. It’s still pretty cute though.
