| It's a 400w metal halide/hp sodium convertible. Right now I'm using an EYE-Hortilux blue MH. My digital camera doesn't display the f-stop, so I don't know what the foot candles are. I can tell you that my 2 catts that are on the top shelf (approx. 8 inches from light source) are thriving and have both bloomed , right now they are putting out roots and both have new leaf/pseudobulb growth. I have 2 phals, both were on the bottom shelf (approx 48 inches from light source) and both are very healthy and both are putting out new growth. As for venting, I have an exhaust fan in the window and three oscillating fans that are all on the same timer as the light. The temp. in the far side of the room goes up 5-10 degrees when the light is on. My central air keeps the room on the cool side in the summer and in the winter it really doesn't matter anyway, I usually just keep the heat turned down. |
