Determining lighting intensity under fluro tubes for phalaenopsis
Hi Everybody,
I just have a quick question in regard lighting intensity and determining plant distance... I have a growth chamber at my work which I'm using to grow my Phalaenopsis species seedlings... the chamber is temperature, humidity and light controller - for growth I've got it set to a constant 28oC @ 80% humidity. There's two growth tubes in the chambers they're Osram L30W/865 tubes and the specs given for them are:
Colortone: Cool Daylight
CRI: 80
Initial Lumen: 1,825
Color Temperature: 6,500
Based on that data is it possible to calculate what sort of foot-candles i'm obtaining and what the ideal placement away from the tubes would be so as not to burn the plants?
