I just started playing PT about a week ago and I love this forum and the game. There is so much helpful information here thanks to everyone who posts it. I got lucky and within two hours yesterday I completed my _bug_ collection and got the sixth magic plant ( it does help being home with a bum foot and on happy drugs for the last week ).

My question is I have downloaded VST and I am still reading on how to use it but I am curious how many old seeds I need to keep in my trays. I have the three trays and they are constantly full. They have seeds from teir 1-4.

Thanks and happy holidays
