Zygopetalum

Zygopetalum is an orchid genus that is easy to grow hydroponically.

Use a healthy plant, it will adapt very fast.

I transfered this Zygopetalum which I acquired recently.

Flowering is finished and it’s end of January now, ideally you should wait till spring (March-April) but patience is not exactly one of my virtues.

I might not haven taken the risk with another plant but Zygopetalum is known to adapt almost immediately to hydroponics, without a transition period during which the plant is fragile because it is producing new roots

I build the water gauge as described in this article:  How to build a water gauge for passive hydroponics.

For plants in individual pots, a growing pot is not required. They are mainly handy for installations with multiple plants.

Procedure:

Remove as much substrate as possible from between the roots and rince them under the tap to remove every trace of organic material.

Remove dead roots (blackened), the roots need to be white as in following picture.

Place the tube at the bottom of the pot and keep in place while putting a layer of clay pellets at the bottom of the pot.

Place the orchid on this layer and keep in place while filling the pot with clay pellets.

When the pot is filled, place the water gauge in the tube (in this case, a Pasteur-pipette).

Cut the pipette at the top rim of the tube.

This is the minimum position indicating that the nutrient solution is at its lowest.

Fill with nutrient solution till about 1/3 of the height of the pot, this is the optimal level.

Care:

  • add nutrient solution when the water gauge is on the minimum position
  • you may also wait a few days: there will still be a bit of nutrient solution at the bottom of the pot and contained in the clay pellets
  • when leaving for a holiday, the pot may be filled up to 1/2 of its height
