I think another consideration here: since you clarified your reasoning, is. If you veg for 55 days then it takes alot longer to finish to full potency/33% amber trichs and you will run out of time if you have a strain that takes longer...not sure how long it takes for NL to finish, anyway, If you veg for 40-45 days then you should have plenty of time to harvest at the right time...ala Zandor
