All my plants are 12 in. Been in the autopot for 14 days . Turned them on 48 hrs ago and none of them seem to be wicking!! I stuck my fingers in about 3in and medium is dry..what do I do to fix this problem?
As long as you are using a suitable substrate that have good capillary action you will be fine the top is always dry that’s where the salts collect….. please take a look at the brochure on the home page and potting up guide
