As our name implies, Indoor Earthworm in O’Fallon IL is an “indoor grow store”, selling all the hydroponic supplies and soil supplies you need to grow vegetables, herbs, and other plants indoors.  Our inventory includes but not limited to: LED grow lights, odor control devices, nutrients, seeds, containers, tools, and furniture from top brands such as Nectar For The Gods, Kind, Botanic Assassin, and Big Foot.

When you think St Louis hydroponics, think Indoor Earthworm

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.

But The Indoor Earthworm is more than a hydroponics store or indoor grow store. Since healthy plants are our passion, we also carry organic soils and fertilizers, seeds, starter plugs, and grow tents.

Frequently Asked Questions:

So what is O’Fallon IL hydroponics?

Hydroponics is a way to grow plants, especially vegetables, fruit, and other plants without the use of soil. The technique was invented in 1699 by Sir Francis Bacon and relies on water-based solutions and solvents plus a growing medium to feed the plant, such as clay pebbles, peat moss, coconut fiber, or Styrofoam. This allows people in areas with poor soil or no space to grow leafy greens, herbs, and other “non-root” veggies such as tomatoes, cucumbers, or peppers.

Why a hydroponics store and not any old garden center?

Hydroponics is a specialized method of growing plants. Therefore, you need a specialized store. Indoor Earthworm O’Fallon IL hydroponics is staffed by people that understand hydroponics. Whether it’s choosing between tables for greenhouses or a grow room to put in your basement or garage, or figuring out what the best medium is for the plant you want to grow, our staff will guide you without pushing you into a design that doesn’t work for your space or budget. Special equipment, such as air stones, air pumps, nutrients, and sensors are available at an indoor grow store.

Not all hydroponics systems work the same, and not every vegetable can grow hydroponically or with every hydroponic setup. That is why The Indoor Earthworm is the premier St Louis hydroponics retailer that can work with you to design the best system to fit your needs.  Stop by to learn more!

What options do you have at The Indoor Earthworm?

The Indoor Earthworm has everything you need, whether you are getting into hydroponics for the first time or looking to upgrade to a new setup. Our team will work with you as you expand your hydroponics endeavors or soil growing techniques. Tell us how much space you have, what you want to grow, and what your budget is and we will recommend a hydroponic system kit or a soil system kit.  We will help customize one to meet your specific needs for you as well as provide you with print or digital resources to take home and continue learning about your hobby.

Why an indoor grow store for the metro east?

Hydroponics and indoor soil gardening is an excellent way for anyone who has poor outdoor growing conditions to have fresh herbs and garden vegetables year-round. Poor growing conditions can include anything from rocky or sandy soil to too much shade to living in an apartment with no permission to grow plants or no deck or patio for potted plants. Hydroponics is also a good way to control the nutrients the plant gets as well as control the temperature and light. No more worrying about extreme heat, too many cloudy, rainy days, or unwanted insects eating your plants.

What are the benefits of St Louis hydroponics?

Many hydroponics kits grow vegetables vertically instead of horizontally, making it an excellent way to grow a large amount of vegetables or herbs in a limited amount of space. There are even hydroponics units that attach to the wall or hang from the ceiling instead of sitting on the floor. In addition to taking up less space, hydroponics also uses less water because the water is absorbed directly into the roots. Because the weather is not a factor when growing indoors, you can have healthy produce at the tips of your fingers all winter long.

What if I don’t have a green thumb? Can your Indoor Grow Store Help me?

Depending on how much money you want to spend, The Indoor Earthworm indoor grow store can sell you a system that takes all of the thinking out of the equation, with timers for lights, watering timers, and even apps for your phone telling you when you need to add fertilizer, water, or nutrients. If you don’t mind having a low harvest at the beginning, you can do everything manually, checking the pH of the solution, playing with different types of food, etc. Whichever route you choose, O’Fallon, IL hydroponics has the right materials for you.

What if I want a traditional garden?

The Indoor Earthworm indoor grow store loves its outdoor gardeners who like to get dirty just as much as our indoor grow customers. We sell soil, fertilize, insecticides, trellises, and heirloom seeds to make sure you have just as high a quality plants outside as you have inside.  Many of our products are utilized by amending the existing soil to help with improving the nutrient density.  Outdoor soil every year needs to have soil amendments to help restore the nutrients that are removed by the plants throughout the year.  One of our highest sought after items is Fox Farm Soil.  This soil is in high demand, and it seems like every time we have it in stock, it never stays long.  We have other comparable products that we suggest trying like our Nectar For The Gods #4 Blend, which is a power house for nutrients.  Check out one of our articles comparing the different soils.  Keep in mind that our stock of soils will vary depending on the supply chain!  Will it be Nectar for the Gods or FoxFarm?  Be sure to check out our soil products in store or contact us and ask more!

St Louis Hydroponics Special Events

The Indoor Earthworm hosts events in both our indoor and outdoor showrooms for our vendors to come and answer your questions about their products. The Indoor Earthworm believes an educated customer is more likely to stay involved in hydroponics or soil gardening.  The educated customer will know how to tackle all of the hurdles associated with growing and they will keep coming back to us for nutrient, and good friendship!

The owners are so friendly and knowledgeable regarding growing. I've bought soil and nutrients here for a few years now, trying to grow my own garden with all the sky-rocketing prices of fresh produce lately. Once, when my plants were yellowing and looking like they were dying, Travis helped me get back on the right track and suggested using certain nutrients and a PH reader to keep the PH balance correct to fix the nutrient deficiency my plants were experiencing. I always tell my other friends to go here for ALL of their plant growing needs! I wouldn't dream of getting the same knowledge from some large-chain Blue or Orange colored store - their employees are not as well-seasoned with plant knowledge as Nate and Travis are!! Highly recommended!!
