Just turned on 175 MH stating 12/12.
Room isn't done yet but couldn't wait.
Don't have HPS yet for flowering so this will have to do...for this batch anyway.
move it closer and toss in a few 27k cfls. it will give u a better spectum for veg. and flower. but i would try for an hps if u can even a small 150 watt hps with that mh would make a huge diff in flower.
