[Resolved] Perlite To Parent Forum April 16, 2019 at 3:39 pm #136 TombsyParticipant Can I use 100% perlite in the Autopots? April 16, 2019 at 3:39 pm #138 JoshKeymaster yes but needs top dressing with pebbles so the perlite does not blow away as it will become dry at the top of the pot. Also need to ensure that no perlite is floating around the AQUAvalve You must be logged in to reply to this topic.
