They're electrically efficient, yeah... But worth the cost? Probably not...

Unless you're using 50w of LED lighting per plant...

Unless you want to grow a stubby piece of clover, you'll need 50 of those Ruby Grow Bars to do anything worthwhile.


For one or two trees you'll get great results with a 150W HPS up top and 4 or 6 CFL's at the bottom
