what early is referring to I believe is an experimental growing method that has not been proven yet.
What it involves is having a Vanda that would generally need a lot of watering, tie a microfiber rope around a few roots and have the end suspended in a bucket of water.
Like this the vanda gets watered without the grower needing to water the plant.
I have not seen anyone use this method to succesfully flower a vanda but I have been curious if it would work.
