If I only bought the 1K Package, but my buddy who signed up using my referral link, purchased a packages of T10K Seeds, will I still get the buddy bonus even though I signed up for a smaller package?

If someone signs up using your referral link, as long as you have an active package of ANY AMOUNT, you will get the bonus for ANY and ALL packages your buddy purchases initially and in the future. You must have at least one purchased and active package yourself to earn a Buddy Bonus.  Your buddy Bonus Percentage is based on the highest ACTIVE package you have in your own account at the time of his/ her purchase.
