Depends on which 150HQI bulb is being used. My sps sucked under a bluer 150. Seemed ok under a cheapie 10k but not great. Now under led, growing like crazy with tons of colour.
However I agree with Steve. Not enough light would show up as he said, at least in my experience. My opinion on rtn, is just looking at them the wrong way causes it. Of course thats ridiculous but its how it seems.
