Compost Tea Dwc HydroponicFor growers in any medium, making a useful Microbe tea has many benefits. It encourages strong roots in DWC and is the best defense against the dreaded “DWC slime,” which eventually causes root rot.

For anyone looking to keep plants in DWC for an extended period of time, I would consider this tea to be essential (e.g. mother plants). In order to boost root health and increase yield, I also use it in my sub-irrigated planter and my flowering room.

My experiments have shown that you can run your DWC reservoir at 70-75F thanks to helpful microbes (vs the 66-70F that I recommended for sterile DWC)

The microbes are revived and can grow more colonies when you make tea. By doing so, you can use a smaller dose than is advised and increase the shelf life of your products. This is comparable to homebrewing with a “yeast starter.”

Zevk Cultivation’s master grower has experience managing DWC on a large scale. No matter how carefully the water temperatures and pH are monitored, he has told me that without a beneficial tea, his mother plants will eventually develop DWC slime.

Without beneficials, a bad strain of bacteria will eventually outcompete everyone else and cause slime/root rot if left unchecked for a long enough period of time. Unlike traditional compost tea, which contains a ton of undesirable bacteria, this recipe yields a clean DWC-friendly tea.

Recipe for Beneficial Microbe Tea:

    • 10 liters (2.5 gallons) of dechlorinated water (Carbon Filtered or Campden tablets)
    • Beneficial Bacteria (30mL Hydroguard OR 30 mL Miicrobial Mass OR 40mL Voodoo juice)
    • Mycorrhizal Inoculant, 15 g (GreatWhite OR DynoMyco OR Mykos)
    • Castings from earthworms in one handful
    • Molasses, 15 mL
    • Muslin or cheesecloth bag
    • Sprayer for 1 gallon (optional for foliar feeding)

The beneficial microbe tea is typically used at a rate of 1 cup per gallon and is brewed for 36-4 hours (70mL/L). This recipe yields 40 gallons of nutrient solution’s worth of inoculated tea. A booster dose of 1 tablespoon per gallon (5mL/L) should be added after 5 and 10 days of the initial dose.

Beneficial Bacteria

The main advantage of UP Beneficial bacteria is that they outcompete other pathogens for resources in your reservoir. No matter how well you maintain sterility, pathogens will eventually enter your reservoir.

Although bacterial growth is slowed by keeping your reservoir at the proper temperature, it is impossible to keep the environment completely sterile. However, pathogens and cyanobacteria won’t have a chance to establish a colony if beneficial bacteria have already done so. Your battles are being fought by a small army.

If you can find it, I suggest Miicrobial Mass. Along with the previously mentioned mechanism for outcompeting pathogens, Miicrobial Mass also makes phosphorus, which is necessary for flowering plants, more soluble.

When inorganic phosphorus is complexed with other minerals, the bacteria produce organic acids to free the inorganic phosphorus from the complex. These acids cause a local pH drop, which solubilizes the inorganic phosphorus and transforms it into an absorbable form for plants.

Mycorrhizal Immunization

A fungus and a plant form a mutually beneficial symbiotic relationship known as a mycorrhiza. The term “mycorrhiza” describes the function of the fungus in the plant’s root system, or rhizosphere. In terms of plant nutrition, root health, and water chemistry, mycorrhizae are crucial.

Most plant species’ roots form a mutualistic relationship with mycorrhizal fungi. The term “mycorrhizal” refers to a relationship in which both the plants and the portions of their roots that host the fungi are present.

Only a small number of mycorrhizal relationships between plant species and fungi have been studied so far, but 95% of the plant families that have been are predominately mycorrhizal, either in the sense that the majority of their species associate favorably with mycorrhizae or are wholly dependent on them.

The Orchidaceae are well known for being a family in which even germination of seeds is fatal in the absence of the proper mycorrhizae.

There are both physical and chemical mechanisms that mycorrhizae use to increase absorption. Since most mycorrhizal mycelia have smaller physical dimensions than the smallest root or root hair, they can explore soil components that roots and root hairs cannot access and offer a larger surface area for absorption.

Fungi have a different cell membrane chemistry than do plants. For instance, they might secrete organic acids that chelate or dissolve a lot of ions, or they might use ion exchange to liberate them from minerals.

According to my observations of mycorrhizal inoculants in DWC, they result in healthy white roots that expand to a much larger size. I believe that the fungi stimulate the roots, causing them to expand significantly more than they would in a deep water culture environment.

Insect Castings

Worm poop is called worm castings. Rich microbiological colonies found in castings aid in the control of insect pests and the prevention of root-borne plant diseases. The water-soluble nature of worm castings enables plants to quickly and easily absorb vital nutrients and trace minerals.

Even the most delicate plants can easily access nutrients over a longer period of time and without burning. Castings from earthworms are highly concentrated in iron, sulfur, calcium, nitrogen, phosphorus, and potassium, according to analysis (NPK rating: 5.5.3)


The molasses serves as food for the good bacteria and fungi. Compared to refined sugar, which should be avoided whenever possible, molasses contains more nutrients. If you can, buy unsulphured molasses.

Teabrewing Instructions

The tea is fairly easy to make. In a cheesecloth, filter bag, or hairnet, place the worm castings, and secure the end with a tie. Starting with the water and molasses, combine all the ingredients in a bucket. For 36–48 hours, add 1-2 airstones and let it steep. Within a few minutes, it ought to begin to foam. Keep an eye out for the aroma; it should have an earthy, mossy scent. Throw away the tea if it ever starts to smell bad.

Any leftovers should be stored in the refrigerator for up to 7–10 days after brewing for 36–48 hours.

Can you manage an eternal tea?

Unfortunately, it does not work out well to run a perpetual tea that you keep feeding molasses. Usually, one bacterium in the solution takes control and supplants the others. Since variety is important for these teas, it is not advised to store them for longer than 10 days.

FAQ Compost Tea Dwc Hydroponic

Compost tea is it allowed in DWC? The microbes are revived and can grow more colonies when you make tea. By doing so, you can use a smaller dose than is advised and increase the shelf life of your products.

Can compost tea be used in hydroponics? In a hydroponic system, compost tea is crucial. Anyone using compost tea in their garden, whether they are growing plants hydroponically or not, will get the best results. There is no requirement to use soil when growing hydroponically.
