I used to have 3 shelves with all T5 HO setup. This year, I have reduced it to just 1 shelf while the other two will be LEDs. On a separate rack, I also have LED lamps (red/blue). All the setups are in ambient humidity which is consistently high by most standards.
Reason for change: My original setups were rather unsafe. Tsk tsk... But it is also because I would like to try using LEDs for CPs...and much to the annoyance of Butch here as I will bug him on a daily basis about the what, why and how of LEDs.
For the following readings on the meter, they are x 100 e.g. 116 x 100 = 11600 lux.
For reference (wiki):
10000–25000 lux Full daylight (not direct sun)
32000–100000 lux Direct sunlight
LED panel - meant for growing fresh water aquatic plants
LED1 - notice the bluish tinge as the temperature colour is 7000K.
T5 HO end - temperature colour is 6500K
