AeroGarden Compatible Grow Sponges (50 pack)
$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.
