Absolutely! Our cloning collars are made of high-quality neoprene. They are not treated in any way. They are non-toxic, and sterile collars, with a neutral PH. Plus, these collars don’t hold any water, so you don’t need to worry about picking up plant diseases, bacteria, or mildew.
On the other hand, the neoprene is firm to the touch yet gentle to your plants. However, we recommend changing the collars when torn or crusty, to ensure proper sealing and increase the chance of healthy produce.
