Tillandsia do not get treated like the "vase" bromeliads. Definitely no water in the crown....Mount them (they look great grouped together...) at an angle, so water will always pour out of the crown. Mist them every day, or whenever you remember to....if possible, put them outdoors in the summer. If you like, you can occasionally mist them with a fertilizer solution (I use MSU), or pour some over them when they are outdoors and can dry quickly. Tillandsia's can't absorb anything from the roots...all moisture and fertilizer is absorbed through scales on the leaves. Blooms look great, but the growth dies afterwards, followed by more growths...typical bromeliad fashion. Take care, Eric
