    They are receiving minimal sunlight from a window to the back left of the enclosure, I'm afraid if I move too much closer it may burn them as this unit is recommended to cover 5 sq ft. and I'm using it for only 1 sq ft.

    However, knowing that Neos are fairly light tolerant I was hoping this would be an adequate distance away.

    Can you see a shadow of your hand over the orchid from the light being projected on them? Is the shadow fuzzy or sharp edged? If it is really fuzzy you may need to do as Amey said and move the lights closer to the orchids. The leds should not produce much heat, but light can burn orchids. Keep an eye on the color of the leaves too. this is an indicator of light levels. I look forward to following your experiment too.

    cheers,

    Just a quick update:

    A lot of the older growth leaves have turned yellow and died off. I'm chalking this up to the light level difference being so drastic and so quick. However I've got new growth on everything but the Tenkei and roots have started on the Shutenno, Oonami Seikai and Tamakongo.

    So far I'd say the experiment has been a resounding success with growth rates higher than I have ever experienced with any orchid.

    I do plan to buy another set-up identical to this one and fill it up with more neos!

    Perhaps I'll take some pictures soon so you can see the results yourselves.

    Just a quick update, here's the results of this experiment on my Gojo Fukurin.

    EDIT: Upon looking back at the old pictures, this plant has grown two new mature leaves and is on it's way to another and the new growth has about quadrupled in size, all in a matter of 6 months or so.

    I've never heard of anyone with Neo's experiencing this growth rate.

    Any thoughts/opinions?

    Bruce, a LED panel can be so wide fitted with so many LEDīs that the "Fuzzy shadow" rule is not valid! I have a nice strong LED panel that is built in this manner andit soes notgive ANY visibly shadow!
