3" Neoprene Inserts for Hydroponic Plant Support - 84 Pack | Hydroponic Grow Plugs for Indoor Gardening, Aeroponics, and Seed Starting | Perfect for Hydroponic Systems, Grow Tents, and Vertical Farms

Neoprene Inserts act as root guards and fit inside net pots to support plants growing in aeroponic or hydroponic systems. Designed for cloning machines, these inserts are preferred over plastic lids because they prevent the cutting or clone from moving around. Simply place the stem of a new cutting into the slit in the insert and watch as it provides support to your plants while still protecting their delicate tissues.
