Foam Collar for 6" Net Pot, White 3/4" Thick - 12 Pack

Hydroponic foam collar fits 6" net pot. These hydroponic foam inserts support plants as they grow, reflect light to reduce algae growth, and reduce water loss due to evaporation.

Made from 3/4" thick white foam, these net pot foam collars are pre-cut to expand around the plant to provide support and secure positioning in the net pot.

They enable better light management, so indoor growers can maintain a healthier environment for their hydroponic plants by reducing algae. Algae growth can lead to nutrient deficiencies that can hinder plant growth. It can cause a drop in dissolved oxygen levels in the water, suffocating plants and weakening them to fight off pathogens. Algae can also clog tubing and hydroponic pumps, disrupting the hydroponic system's efficiency and overall productivity.

Hydroponic foam collars help reduce water loss due to evaporation by adding an insulating layer on top of the hydroponic medium. 

Sold as a pack of 12 hydroponic foam inserts can also be used as cloning collars. In cloning or seed starting, young plants lack developed roots and are vulnerable to dehydration. A foam collar helps maintain a humid microclimate around the stem and roots, reducing the demand for misting or a humidity dome.
