Read Thread: Planning a plant
This is ok if you have a general idea of when you want to plant. I have had boxes on my reserved list for over two years just waiting for the best place to plant. When I finally plant them, I just change the date when I activate them.
So you're saying a reserved box can go past it's estimated plant date, and it doesn't go active automatically? Oh, good. I thought maybe …
I'd recommend doing that after you activate the clues. Off the top of my head, I think AQ might automatically set the plant date to the activation date because I know a lot of people don't edit that sort of thing when they make a box live and if you make it live, there's a good chance that is the plant date. (Or, at very least, very close to it.)
I could be wrong.... this is off the top of my head and I'd have to look at the code to be 100% certain. But there's definitely no harm in changing the plant date after it's activated and you have to edit the listing anyhow to mark attributes, add a location and anything else that's specific to the box type you activated. (The reserved listing only let's you add options that are the same for all box types.)
