i keep putting plants out till the about aug 31 when flowering begins here in tn. go to this and put in your latitude. it will tell you when your times change in your exact location.
if you want weight, you'll be forced to give 'em a few hrs. of artificial light beginning about the middle of july...if you can't give 'em more than 12 hrs. they'll flower. start planning for next year NOW!
im in the same boat, just got mine though, should be able to get them out within the next 10 days, you should be ok, you just wont have the max, i did the same thing last year haha
ya you'll be fine. the only advantage of having them out earlier is longer vegging time. where i live the most growth takes place from june 1st to late july
