end of Feb beginning of March, they tend to be a bit pokey so start early i do
it works for the zone im in and do imagine it would even be better for you as you have a longer growing season than i do
i start all habs,bhuts and scorps around this time (
to the chagrin of my wife) LOL
it works very well for me here and there also nice and large and can take the stress of being transplanted better, i did not lose one superhot due to transplant shock this year
plus i had pods about two weeks earlier than my friend who started his at the end of March
thanks hope this helps your friend Joe
