LED GROW

i searched but i have no other pic of around 30 days 12/12.

that's why..

i love her!

BTW i give 100watts of led light for 50cm x 1 mtr, i could give 200 watts maybe the plant would give more weed but the main goal is reducing electricity use, not the yield.( i use 3x a familyconsumption in my home!)

I use as i remember well 10x450nm and 40x660 nm = 50 watt x2 = 100watt

This spectrum is not enough but i use now and then a 600 watt with a spectrum  from around 450 to 660 that covers the wants of the plant , if you use leds alone you need the white and orange color to , blue and red is +/- 90 % of the need of the plants, some sunlight can help too for the other 10%. The modern leds have the complete spectrum if you want leds only then you have to use the modern led equipment, the equipment i use is called UFO's.

EDIT

They have 2 fans per UFO for cooling but there is almost no heat coming from the ufo's , in winter its better to use hps for heating up the room otherwise you should use a heater in the room, a hps is better then.
