New Year, New Clean! Keep your Grow Tent Thriving

As we welcome the new year, it's the perfect time to give your indoor garden a fresh start. Cleanliness in your grow tent or indoor garden isn't just about aesthetics; it's crucial for the health and yield of your plants. Issues like mold, pests, and dust can create an unhealthy environment for growth, leading to diminished yields and even plant death. Even more important is regular maintenance which not only increases the lifespan and efficiency of your equipment, but also decreases the amount of work you need to do when cleaning. This guide will walk you through a thorough cleaning process to ensure your garden thrives in the coming year.

What You Will Need

To get started, you'll need some essential items:

  • Mild detergents and disinfectants safe for plants
  • pH meter cleaner
  • Microfiber cloth
  • Bucket of warm water
  • Vacuum (shop-vacs are ideal)
  • Protective gloves
  • Temporary housing for plants and equipment

Cleaning Guide and Tips

Common Mistakes and Prevention

  • Overusing Chemicals: Excessive use of harsh chemicals can damage equipment and harm plants. Always follow dilution guidelines.
  • Ignoring Safety Protocols: Always unplug electrical equipment before cleaning to prevent accidents.
  • Neglecting Regular Maintenance: Regular cleaning prevents the buildup of harmful pathogens and pests. Schedule routine cleanings.
  • Protect Your Plants: Gently remove plants and carefully transfer your plants to a safe, clean area with similar temperatures as your grow tent or indoor garden. 

Wet Equipment

This equipment is in regular or constant contact with water and is prone to biofilms, mildew, and mold. If any of the equipment is electrical be sure to check all electrical components to ensure they are not compromised to prevent any damage to plants or injury. 

  • Hydroponic Systems: Once the plants are removed, flush the entire system with a slightly acidic cleaner. If necessary you can soak drippers, emitters, and other parts/accessories. Be sure to rinse thoroughly with warm water to ensure all chemicals have been washed out. 
  • Humidifiers/Dehumidifiers: Empty, clean, and dry thoroughly. Check the reservoir and diffuser for mold, wash with a mild detergent if necessary. 
  • pH and EC Meters: Soak in a pH cleaning solution. The exact makeup varies from brand to brand but is typically some version of diluted hydrochloric acid. 
  • Spray Bottles: Clean and sterilize to remove any old solutions and prevent contamination.

Dry Equipment

This equipment is rarely or never in contact with water and is prone to build up dirt and dust buildup. You will want to check all components to make sure there is no buildup that can lead to overheating and failure. 

  • Grow Tent Fabric: Check for damage to fabric and zipper that can lead to light and air leaks. Vacuum off any dust and debris. Wipe down with a mild detergent and air dry completely to prevent any chance of mold/mildew, a dehumidifier and fans work great for drying. 
  • Lighting Fixtures: Dust carefully and check for any wear. Check bulbs and replace if necessary/applicable. Marking your bulb with dates can help you determine if they need to be replaced. Follow all user manual directions and cautions. If surfaces are soiled, you can use a lightly damp cotton or microfiber cloth to wipe it down, a mild glass cleaner can be used to remove heavy soils. Be sure not to scratch the surface by rubbing debris or abrasive cleaners on the surface.
  • Fans and Air System: Clean fans and replace clogged filters, ensuring optimal airflow and a long lifespan. Using a vacuum with a brush attachment to gently brush and remove the dust/debris from the fan. You can use compressed air if necessary for small crevices near the bearing. Check for and then clear any large debris like leaves or growing medium in ducting, using a filter will greatly reduce dust and debris accumulation.
  • Reflective Materials: If your reflector appears just a bit dusty to the naked eye, you are probably already losing around 5-10% of your light, and if it is heavily soiled you could be losing 20-30%. When cleaning solid reflective surfaces like reflectors you can scratch or damage the surface when cleaning as existing dust and debris can be abrasive. Be sure to follow the instructions in your user manual.
  • Shelves and Racks: Organize and wipe down. Check that all nutrients and solutions are not expired or spoiled. 


  • Pots and Trays: Sterilize and wash, or replace if necessary. Waste nutrient buildup from runoff evaporation can cause nutrient lockout.
  • Gardening Tools: Clean, sharpen, and oil as needed. Be sure to sterilize anything you use to trim plants to prevent infection and disease.
  • Soil and Mediums: Replace or refresh to ensure healthy plant growth. Reusing soil can be done in certain gardening techniques but it should be properly flushed and cleaned to prevent nutrient buildup and pest issues. 

Reassembling and Organizing Your Space

  • Efficient Organization: Try to store tools outside the grow tent but nearby to maximize your space and for easy access.
  • Air Circulation: Position fans and air systems for optimal temperature control and energy efficiency.
  • Maintaining Cleanliness: Use mats or trays to catch soil and water spills.
  • Lighting Setup: Ensure your lights and reflectors are placed for maximum coverage and plant growth.

Wrap Up

A clean and well-maintained grow space is the foundation of a successful indoor garden. By embracing the new year with a thorough clean-up and reorganization, you set the stage for robust plant growth and bountiful yields. Remember, the effort you put into maintaining your garden reflects in the health and productivity of your plants. Here's to a prosperous and green New Year!
