oh F yeah we have an answer!
60 days counting back... it is basically june 1st for all intents and purposes... bringing your outdoor date to April 1st... the equinox being April 21st... they revegged a bit when you first put them out! Even though last frost date where you are at may be earlier than the equinox, your light cycle is not at >12/ 12 yet. There are better outdoor people to ask though.
