I'm about to set up two new grows, and I've heard before that 600 watt bulbs rule over 1000 watt bulbs for efficency. They dont put out quite as many lumens as 1000w but are much cooler. My ? is are they worth having overall? I've grown for 7 years using only 1000w bulbs and they generate alot of heat but also generate alot of bud, so if anyone out there has used both and has a definate opinion about this subject let me know.
