Is it an incandescent bulb? That is, does it look like a regular light bulb and plug into a regular light socket? If so, don't use it! It will add way more heat and way less light than your other bulb. You'd be much better off with a 6500K compact fluorescent or something similar.
khronik Reviewed by khronik on . would this benefit my grow at all? i just started two clones of blueberry about a week ago under a 70 watt metal halide in a cabinet, and today i found a 65 watt plant light (the ones that have a blue bulb) in my garage. i was wondering how this would effect my grow. the carton says it makes plants greener and healthier, but i don't think the makers had marijuana in mind.
