how big is your room? i’ve always read that 2 600’s are better than a 1k for
an even footprint. to be truthful with you i ran a 1k hps and 1-315 cmh for my first
grow and it worked well.really didn’t grow as big or as tasty of weed as the 315’s alone.
but now there is about 1900 watts vs 1315 so that makes some of the difference.
either way you go will be an improvment .
