Migro Veg
Default Migro Veg

I ordered this today and wanted to know what your thoughts are on it. I ordered this one because it is supposedly very efficient and has lots of blue (I hate yellow light.) There is also a full spectrum version with much more red and a lot less blue,, but it looks yellow.

I'm just wondering how light-demanding plants I can grow.

That PPF looks mighty fine.

Itís a bit light on the red end of the spectrum, but in my experience, orchids are less sensitive to that than some plants.

MIGRO VEG light
I have white LEDs in the 3000K, 3500K and 4000K spectrum. Most of my cattleyas are blooming at 150-250 ppfd for 12-14 hours. Lower light plants get 100-150 for the same photo-period. I think the color temperature recommendation for orchids are outdated and based off of the spectrums of fluroescent and HID lighting. I have not noticed any differences between 3000k, 3500k or 4000k growing up seedlings and adult plants. Red and far red is supposed to promote tissue elongation and blue light should suppress elongation. if there are any differences I cannot see them in my orchids. I will note that the 4000k light I have is way to "clinical" in color and my eyes prefer 3000-3500K so I'm moving to replace the 4000k board. It sounds like you like the bluer white light so you should be happy.

From my experience going over 5000K starts inhibiting the elongation and causes the plants to stay compact. Who wouldn't want a 10-12" plant with 7-8" blooms?
