I have a feeling it does work differently than cobs and wish we could see someone here on RIU do a grow with one without ridicule.

He asked if they're 95% efficient, not if they "work differently". I've got an idea though... why don't you (someone) buy a spectrum king (liar king).

it will grow buds..i tried it..i coulda done better..and so could have the sk 400+

it will take more sk watts than cob watts to do it..

diy cobs will grow better buds..

sk is "ok" but over priced and over hyped..
