I read your post, and apologize if my reply wasn’t clear. There is currently no spring sign up for Pakistani Chitral Kush. This one was for the Fall box. If you would like more info on how the spring and fall boxes work, see this post I linked below 
“Seeds are mailed out twice a year in the Spring and the Fall, depending on when each seed run is complete”
“Seeds sent to distributors between October and March will ship in April and seeds sent between April and September will ship in October”
