Does anybody have experience growing above the light

[Nontapatwatanawigun]

I kindda run out of space for new orchids and I have to get somewhat creative. By above the light, I use the floor light that face upwards. So, the light is under the orchid and the orchid gets light only from the underside of its leaves. On top of the pot itself is shadowed and the only leaves that get the light are the ones that hanging down the side of the pot. My guinea orchid is a mature Phal. Gigabell with foot long leaves. Will this cause problem especially the new leaves that will get no light at all until it’s long enough to finally hanging down.

I don't know! Please tell us how it grows.

Hi wigun,
everything I know tells me in theory it should work but I have never purposefully done it - I have shone a light up against a reflective surface that would then shine down on the plants. This was done because of height restrictions mainly as I couldn't fit the light above them but I could have shone the light from below. So although in theory yes, I am guessing you might have to provide a bit more light if you only light up the underside, I personally prefer to shine the light form above.
Some of my vandas that grew towards the light would get turned around every so often to straighten the plant, the leaves would be facing the wrong way when the plant is turned like this and it can take months for the leaves to turn around in which time they are being illuminated from the bottom so I don't think they seem to mind too much.

Eventually what will happen I am guessing is that the leaves will start to curl and bend upside down to best collect the light.

The prediction is that the stem and leaves etc will grow toward the light. So if the light comes from down below, then the shoots etc will likely just head toward that direction.

Can you invert them?

Or better, mount them inverted?

I grow a lot of my phals upside down and I also use reflected light to grow most of my seedlings for gardening.

Both will work just have to adjust as you go
