Stick answered grow question 3 years ago Hi @Slimsativa! Yes this can be useful in closed/classic pots, but not with AirPots/SmartPots. I see you're using regular containers, so go ahead! This will help roots to auto-prune (prevent rootbound) and reinforce oxygenation. But remember to wash your clay balls twice before using it, and 5cm might be too much (2~3 is enough). Happy growing! :facepunch:
