That is way cool! Thanks for sharing. I'm not into tills (or whatever the short name is for them) - I'm more into neos, guz and aechmeas. I once had orchids (phals) that I had mounted in such a way that they needed daily watering. With a busy life and job, I couldn't keep up with it. That is a great solution!

So, update on my suction cup air plant garden.

I've started watering with distilled water, and once every two months diluted orchid food.

This way the glass stays clear. The window wall has been very successful, I've added several species, all of which have bloomed and grown. I got an excess orchid that was dying and over crowded, it bloomed and I'm getting it back to health to separate the bulbous bases into several containers.

This week I replaced the towel (which the orchids had rooted into) with a long piece of clear plastic that directs the water spill over into the tub. Because the plastic is non-absorbant it lets the mist pool and the orchid roots suck it up, growing much faster and being much greener now.

I laid some clear plastic packaging, cut into a neat rectangle, down, and used 1.5 inch wide clear packing tape to hold it in place. I didn't upload photos because you can't' ...well, see it in a photo being clear and against privacy glass.

The other thing I did was buy craft store jewelry wire, and begin forming it into shapes to hold the plants. Up close it's kind of cool and holds the plants out at different depths. However, the effect is quickly lost when stepping away. I think I'll have to bend the wire such that plants are more than 8 inches away from the window, at the edge of the spray pattern for the wire wrapping to be striking,

I'm thinking about putting the orchids, once split, on little cages so the roots can reach pooled water but there won't be a container and bark that would rot. I know it doesn't look super healthy in the photos but it was on the way out when I got it as a reject freebie, they've improved. You can sort of see the plastic in the close up photo with the wire wrapping. It's super fun to move the plants around, kind of like living fridge magnets.

With the multple-times-a-day misting there's not really a need for wood to absorb and slowly release moisture to the orchids so I may be able to go totally without media?

I've also been turning a soft drink bottle, with the wrapper pulled off, upside down onto the mister reservoir. This allows the mister to run 2-3 week between refills at 30 second 2X a day misting. I've changed the batteries three times since starting, so batteries last about 1.5 months at a time. The unit came with an AC adapter, but I don't want live wires running around a bathroom.

I think I'm going to get a battery charger and c batteries to go with from B&H photo so I'm not throwing away batteries once every two months,

I think, if I can perfect the setup, I'd have a reservoir hold a little over 1 month of water at a time (about 5 liters) and add a sprinkle of orchid food the day before I refill. Then I'd do refill, battery recharge and any plant moving around or potting I want as a 2 hour a month hobby.

If I want to put about $250 into this, I'll switch out the mister with two ultrasonic fogger bars (several ultrasonic fogger discs along a rectangle) in a cut open PVC pipe with a reservoir at the end. It would require an AC adapter that I'd wire along the ceiling ...and I'm not that committed yet.

I have made ultrasonic fog curtains before, and they are fantastically pretty. I sort of envision a fog curtain 2 to 3 times a day gliding down over the plants

Here's an internet photo to give the idea of the effect, but I would want it on a 2 foot wide scale.

It looks like you are doing the right things and the plants are enjoying the attention! Thank you for keeping us posted -- please continue to do so!
