you should be able to reply at anytime you can either call them and you will either be sent a form or you should be able to get it offline. the only thing i can think of that may keep you from doing it right now is that I think the cards have registration numbers and if they have not got to yours yet, they will not be able to match your grower request to your recommendation from Dr. you and your potential grower should be good to go as long as you have your paperwork in order. hopefully that was helpful, in all honesty you can't go wrong by just calling OMMP and hearing it from the horse's mouth. :hippy:
