4 FEET Tank Lighting

[Abhi]

finally done with 2 150w mh

Make and model ? Colour spectrum of the bulbs? Even I am planning to move to MH, my LED experiment hasn't given me the desired result.

Any specific reason Mitty why you preferred these two colour temperatures ? These temps are for commercial use....typically what we call as yellow light. Technically , they are known as warm white and lack specific wavelengths of light beneficial for plant growth - blue for example.

I think 300watts of Mh will do the trick

Amol Matrix has confirmed the LEDs he uses are 6500 kelvin and allowed great plant growth. Why don't u try those Abhi? The LED Expo is just a month or two away, why not wait till then?

Mitts, why not message Matrix???
