Hello Hydroponics customers love the Nutrifield Pot Liner for their coco media-based growing systems. It's the perfect solution to keep coco intact until it's firmly bound with roots. The pot liners are thoughtfully designed with woven sides, allowing proper aeration for the media, while the netted underside prevents water-logging issues. Additionally, the convenient drawstring makes tying things up a breeze once you're done with the media. With Nutrifield Pot Liner, growing in coco media has never been easier and more effective!
