Is self watering pot a game changer in Orchid cultivation? If so, the concerns of potted media getting bone dry are allayed and the choice / selection of media in a given orchid under the prevailing environment can be reoriented.Since the plant container is buddied with the bottom reservoir there will be more retention of moisture available for the plant.
The next concern is fertilising the plant ;looks feasible to fill the liquid fertiliser in the desired concentrations/ dosages in a 5 or 10 ml syringe (used in clinical use) and point the nozzle with out the needle and inject the content in the general area of the root ball.
My sincere thanks all the senior members participating in the discussion
Feeding is easy - just make sure the water supply contains a tiny amount of fertilizer. In nature, most of the mineral nutrients come from host plant exudates and accumulated detritus on the forest canopy, which washes down to the plants every time it rains - more or less constant, but VERY dilute, so you can mimic that.
The appeal of growing orchids is participating in their care and nurture. Many people grow their orchids in semi-hydro, as Ray inferred by advising you to go to that sub forum. What you imply is reported and discussed there.
Semi-hydro is not workable for me. What is “game changing” for me was when I changed my potting media from bark to NZ Sphagnum Moss. I found my plants did very well for me, in my environment.
