Wow! Four inches tall and only one month old...that's amazing, Ken! They are all looking good!
Last year, I grew a community of adeniums in a 5" clay pot...I had added a little more humus in the soil and watered slightly more often than others in the plastic pots. One of the adeniums bloomed at just over 7 months old (my third bloom from seedlings):
Looking forward to seeing your blooms, Ken. In the meantime, please do keep us updated on their growth.
