I wait till the pot is dry then water lately every 2 days but early it was every 3. I use the soft pots they recommend and I feel the bottom if it is moist I wait... those roots need oxygen as well... they die from over watering but not underwatering...after a few weeks you learn by looking at them and you know when to feed them...That's a great idea! I'm going to check to see if my local grocery store has the same set up. What has your watering regimen been like?
