New grower what strain should i start on....600w

I GOT A COO LIL SPOT FOR MY REFLECTOR ITS A 8'' AND MY 600W HPS/MH LIGHT SYSTEM AND ONLY WAT TO GROW 2-3 LADIES GONNA GET CLONES AT MY DISPENSARY BUT WAT SHOULD I LOOK FOR WHEN I BUY THEM AND WHAT STRAIN PLEASE HELP...AND AM GOING SOIL

what you lookin for? Something to fall asleep or something to make you think and stay up? Possibly something in between such as a hybrid mix?

Also how fast do you want till harvest & how tall will you let them get?
