It's not "brightness" so much as "usable light band(s)".
Brightness helps orchids, and all plants, look good...but it's not always supplying the 'type' of light they need to produce there own food.
And "I" don't use those fertilizer sticks in my orchids but that's just me.
Let's see what others have to say about them.
I like a "1-time, 1/2 amount, twice as long" kind of feeder of my orchids. I don't like constant-feed stuff on anything but my spider plants and wandering jew (both heavy feeders).
I also don't use different kinds of fertilizers on the same plant...at the same time.
There are times I will use a different fertilizer (food) at different times of the growing year..again, except my spider plants and wandering jew.
But I'm curious to see what others will reply.
I live in Florida so my plants get a good dose of light so my feeding requirements tend to be lower then for folks up North.
It's wonderful to read you enthusiasm!
There's a lot to learn...not really, just some general rules.
But once learned many orchids become real easy!
