The Indoor Earthworm in O’Fallon IL has everything you need to grow healthy plants indoors or outdoors, with or without soil. For over six years, The Indoor Earthworm has been the O’Fallon IL hydroponics headquarters and is one of the only independent St Louis hydroponics stores that you can come and visit in person. Unlike larger garden stores with only a soil garden section, as a hydroponics store, we can help you select the best hydroponics system for your needs along with a great soil selection.
