I’m having a problem with scum in my reservoir, what do I do?

We recommend covering your nutrient water reservoir with a white lid to decrease light and therefore decrease the likelihood of unwanted algae, bacteria or fungal growth. Keep your room and water at the coolest recommended temperature for your plants. Clean your reservoirs between crops and plant stages of growth. You can use bleach or hydrogen peroxide to clean them, but rinse well to remove all cleaning product residue before growing again.
