Orchid Experiment Update

It appears as if my cuttings are still somewhat alive.  I ended up tossing the root system. The three roots looked good for a few days, but then mold appeared, so I took them out of water to hopefully stop the mold. That caused them to shrivel up. When I trimmed it again, everything was brown and hollow. Bummer. 

The green onions are doing well, as expected. 

See the tiny leaf? I'm hoping that will grow bigger. 

The flower stalk is mostly green, but there is a yellow part in the middle that doesn't bode well...

When I refreshed the water, I put in a drop of tea tree oil to hopefully keep the mold at bay. So far, so good!
