I have a 3x3x6 grow tent. In it I have a vivosun 600 watt led and I just put a hlg 260 v2 rspec in there too. If I can keep the temperature down should I keep both leds in there? Will the plants be able to use all the light and increase my yield? Or will it just be a waste of power. And if if it does increase my yield is it worth the extra money on my light bill
