well that all depends on where u live and when your last frost date is.. and if your gonna start them inside no one can help u not knowing this stuff..
not far from ya.new york here.i start mine inside on april 1 then they go outside may 15.it makes so much of a difference if you give them that 6 weeks to grow inside.and when you put them outside make sure you protect them with chicken wire from deer,rabbitsect cause they love them.lost alot to them fuckers
done may 15 in new york everytime no problem.you may have to wait one week in mass. but as long as there under lights and still growing it does not matter if wait.
good luck
