AeroGarden Compatible Grow Sponges (50 pack)

Rating: 4.9 out of 5 (10)

$15.00

Most grow sponges are made from peat moss, the mining of which releases vast amounts of carbon into our atmosphere. The Urban Leaf grow sponges offer the same performance, but instead of being made from peat, we use coco coir - which is an agricultural by-product offering very similar water retention properties as peat.

These sponges differ from our Bottle Garden 'Smart Soil' kit in two ways 1) they are a different material (coco coir vs pine bark based) and 2) they are not pre-treated with hydroponic plant food. In order to use these sponges you would need to add liquid plant food separately.

50+ hydroponic grow sponges in a recyclable bag

Because coco coir is a more sustainable alternative to peat moss! We look forward to a day when the gardening industry moves away from using peat moss entirely.

Sponges have a small divot on top for placing seeds.

This is a replacement part for an Aerogarden unit and some other countertop hydroponic kits

FAQs

They are the same size as the sponges that come in an Aerogarden kit.

No, they are 100% proudly made and packaged in the US.

Our sponges are made from coco coir - a by-product of coconut processing (it’s the outside part). Not only is coco coir more sustainable compared to other materials like peat moss, but some people believe it also does a better job of managing pH.

Thanks for the question. If you’re going to be storing these Aerogarden-compatible grow sponges then we recommend drying them out on a rack or try first. If there’s no moisture, there’s no mold.

You have to cover the top of each pod to let in as little light to the tank as possible. If not, you are creating the perfect environment for mold and algae growth. Hope that's helpful!
