I do not have your particular Onc, but pretty much that is how long my Onc blooms last, about a month, lucky if it lasts for 2 months. Onc are so thirsty, I sometimes intentionally leave them in water for a few days, but my area is quite hot and dry, so it enjoys it. Plus there is good air circulation around the plant. I do that especially when we are bound to have triple digit temps here. But I make sure to drain that excess water too afterwards.
Glad your plant is responding well to your Leca in a glass
