I bought one while in Arizona in 2018. Excitedly, I started it as soon as I got home. The Saguaro Cactus is a VERY slow grower. Do not expect it to be as quick to sprout from its seed, like the instructions say they will. But with patience, they will sprout and grow. I kept mine on my window sill where it could get indirect sunlight. Do not keep it wet, but moist. This company, Desert Gatherings, is very responsive to questions you may have. I had fun growing my Saguaros until my cat destroyed them. Now I'm back to starting over. Would recommend this kit for anyone with a love of cactus and growing plants from seeds.
