~ When growing in a mason jar, you are following the Kratky method of growing. It is suggested to use a mason jar that is darker in color or covers with a covering such as a sock. Your jar will require proper fertilizer as well for the best results. Such a fun way to grow without using a ton of electricity!
All our Lids are 3D printed with love using PLA. PLA is an eco-friendly plant-based biodegradable renewable material. Please note PLA is sensitive to very high temperatures. If your lid becomes dirty, simply give them a quick wash in warm water, and they will be good as new!
