New Grower grow cycle for two grow areas

[darkportal]

Hi guys I was think of seting up a grow were I have two tents one for seedlings and one for the rest of the grow. I want to do this so I can have two plants going at all times and then have the two plants moving throu the cycle to get more plants going in a limited space So I wanted to know at what time I would have to plant the second plant to be able to move it into the bigger tent when the first plants ready to harvest. Also a setup for a closet to be able to do this would be great.
Thanks!

Keep in mind, with autos you can do this all under one light... they all can take the same light cycle.
