    Thanks for the info, Jacob! I'm about to transition to a situation where I may be growing some under lights (as opposed to entirely windowsills or outdoors now), and I definitely agree with the good sense of your plea for more empirical data. I don't grow many Angs but I'll try to use my light meter more often to record levels and note how my orchids respond. I also hope to obtain some reliable temperature and humidity-measuring equipment soon.

    That is a great idea Jacob. I know your plea was to everyone in general -- but since my comment sparked the discussion, here's proof. :D Yes, I do have a light meter. (And I really like this particular model.) I had another one before that was cheaper, and when I got this one I was amazed at what the light conditions actually were. What you think is "bright" might not be that bright.



    To be honest, these days I usually measure when I am moving things around or when I have a plant that clearly needs something else. It is a great idea to document some of the growing conditions more specifically. And an even better idea to share this information with each other. There aren't enough angraecoids alive in the world for them to be killed off because we didn't know more about suitable conditions. So, I'll try to take more quantifiable notes.

    Jacob you're astute observation about the pattern of yellowing under artificial lights is very true, and I'm glad you posted it because I am observing this now in some of my plants after being under the lights for a time. I have purchased the light meter you recommended a while back which is digital and will be re-adjusting everything! Given your meticulous documentation, would you happen to have specific information to share regarding different aerangis/angraecum/aeranthes species?

    Hooray! I am glad to read all your enthusiasm and shared wishes for better record keeping and sharing of cultural data. :rolleyes: I look forward to more learning and sharing with you folks. Also, I'd like to nudge to the lurkers out there to join in as well. Don't be afraid; most of the rude people have left OI, so you don't have to worry about being bullied.

    Nate, I am glad you'll be getting a light meter at the outset of growing under lights. I use the less expensive Hydrofarm model (shown in the attached image).

    Reyna, I agree, it can be surprising sometimes at how different light levels can be from what our eyes alone perceive. I too keep a light meter handy whenever I move a plant; I write down the level it was at before and after I move it. These records have already proved useful for myself and I hope in time they will prove useful for others.

    Calvin, glad you got a light meter! Sorry some of your plants eventually yellowed. I bet you are really having an interesting time getting better acquainted with your new LED lights and the effects they have over time on angraecoids. Your observations will be valuable for many of us! I am keeping notes, but I haven't yet collated my data in a format that I can make readily available at the present time. However I can certainly look up species on request and see what information I may have on them. I am still learning a lot!
