the 6700 for sure! then from there pick whichever is closest to 6700k.. that is optimum for plants

Does it matter if the 6500k is only 28 watts n the 10000 is 54watts

I'm pretty sure it depends on your fixture... like my t8 fixture only takes 15w bulbs and my cf fixture only take 40w bulbs. Umm I don't know much about it... I just know the light spectrum that's best for plants...

I think you should really write your list and add in the bulb wattage. maybe then others can be of more assistance

An NO bulb in an HO fixture? Talk about overdrive. The bulb's life will shorten, or maybe even blow. Might want to ask JetaJockey or Aqua_Chem.
