question on keeping air plants in a terrarium
Hi everyone. I recently bought some air plants and some wall terrariums to put them in. These 'wall terrariums' have flat backs so they can hang on the wall, with a round opening up top through which you insert the plant.
My question is....how much bigger will these plants get over time, or will they not grow much at all? One of my air plants has rather spread out 'leaves' and my fear is that while I may be able to stuff it inside the terrarium, that I may have difficulty then getting it out.
It's my understanding that air plants need a periodic water soaking, and then they need to air dry. But if I have plants that I can't get back out from the terrarium, I suppose I could just add water now and then, let it soak for a few hours, then dump all the water out?
Would it be problematic for some reason if some of my plants theoretically stay inside their terrariums and never can be taken out (because they can't fit through the hole)?
I'd also read that the way to know if it's time to water an air plant is that....if the plant feels 'HEAVY' it needs water, and that when it feels LIGHTER it does not need water...is that right? Though that actually sounds counter-intuitive...I would think that when the plant is dry, that is when it would be at its lightest weight...
