Full product description
Between grows, an AeroGarden reservoir accumulates two things: hard-water mineral scale and precipitated nutrient salts. Both settle on the pump and in the basin, and both restrict flow to your next crop.
This is a 50% citric acid concentrate that chelates and dissolves them together. Fill the reservoir, add a teaspoon, circulate for two to three hours, drain and rinse. Three ingredients, no dyes or fragrance, and up to 95 cleanings per 16 oz bottle.
Features:
- Fits every AeroGarden system – Harvest, Harvest Slim, Harvest Lite, Harvest 2.0, Sprout, Bounty, Bounty Elite, Farm 12, Farm 24, Ultra, Extra, Classic and all other models.
- 95 uses per bottle – Up to 95 full descaling cycles at the standard dose, or 47+ at the heavy-buildup dose.
- 50% citric acid super concentrate – Citric acid, sodium citrate and water. No dyes, no fragrance, no hazardous chemicals.
- Clears scale and nutrient salts – Chelates and dissolves hard-water deposits along with the nutrient salt buildup specific to hydroponic reservoirs.
- Pump-safe – Safe for all AeroGarden pump types. Food-safe ingredients, made in the USA.
How to use:
- After harvest, empty and fill the reservoir with fresh water.
- Add 1 teaspoon for standard cleaning, or 2 teaspoons for heavy buildup.
- Circulate for 2 to 3 hours.
- Drain and rinse once before starting your next grow.
