Question on T5 banks
If you are using T5's, do you mix 6400K and 3500K? If so what percent? I'm leaning this way but need a forum opinion. Thanks.

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)

Not sure yet. Yeah, I knew you were using one kind of light. I just wanted to know if others are using a blend of warm and daylight and how much.

I was thinking a 50:50 ratio would be good.

How do you figure the average Kelvin light temperature? If I do a simple average (assuming 4 bulbs - 2ea 6000K and 2ea 3500K) I get about 4800K - a bit on the warm side for daylight. If I figure 3ea daylight plus 1ea warm I get about 5400K - almost the same as average sunlight. Just curious and this is why the original question.

A lot info that I have seen recommends a mix of 3000k and 6500k. I am using equal numbers of 3000k and 6000k (ordered 6500k but got 6000k) I also have some that are called 'Full Spectrum' but have not used any of these yet.
