That's an excellent question. I would fill the reservoirs as usual for this reason: if the wick drys out, you may have to top water again to get it restarted. If your soil is properly light (plenty of perlite) and your wick is the right size, you should not have any trouble with it over-wicking extra water into the already wet pot.

Thank you! That's what I was nervous about, the wicks drying out. Yes, my soil is nice and light with 50% perlite.
