Cleaning the reservoir of the Hey abby Grow Box after harvest is an essential step in maintaining the health of your indoor grow system.

Updated over a week ago


Cleaning the reservoir of the Hey Abby Grow Box after harvest is an essential step in maintaining the health and efficiency of your indoor hydroponic cannabis system. Over time, nutrient solutions can leave residue and accumulate salts in the reservoir, potentially leading to imbalances, clogged components, and suboptimal growing conditions for future crops.
Thoroughly cleaning the reservoir after each harvest helps to reset the nutrient environment, ensuring that your next batch of plants receives the ideal balance of nutrients for optimal growth. Additionally, this process helps to prevent the buildup of harmful bacteria, algae, or fungi that could negatively impact plant health. By regularly clearing and cleaning the Hey Abby reservoir, you can maintain a pristine, efficient, and productive indoor hydroponic system for consistent, high-quality cannabis yields.


  1. Turn off the power and unplug the cord of hey abby.

  2. Remove the plant (if there is any).

  3. Unplug the connection of the water pump, air pump, water sensor, and any other connections.

  4. Prepare a solution of warm soapy water (mix 1 - 2 tablespoons liquid soap and 950ml/1 quart warm water). Add 1/4 capful of bleach per gallon of water.

Clean the Tank

  1. Take the tank and water to a sink. Clean the tank and tray covers with the cleaning solution made in step 4.

  2. Remove all visible green/brown algae, mineral salt buildup residue, and any slimy substances that may have accumulated from the previous harvest.

  3. Rinse thoroughly to remove the cleaning solution.

  4. Cloth dry or air dry for 24 hours before filling the tank with fresh water. This will prevent chlorine poisoning.

  5. Once the tank is clean and dry, new water can be added. It's best to let water circulate for 24 hours before adding a new plant to the device.

Clean the Water Pump

  1. Clean any roots that may be in the strainer intake basket;

  2. Wipe out/dry off the inside of the reservoir - removing any residual nutrient solution or water;

  3. Fill the reservoir with 1 gallon of water and 1 cup of bleach;

  4. Run the drain cycle in the app to clean out the pump and the hoses;

  5. Empty the reservoir of the bleach solution, rinse it out thoroughly with fresh water, and then dry the reservoir;

  6. Repeat the process with fresh water, and re-drain 2-3 times to ensure the water pump is free of any residual bleach.
