**5. Overcoming moss in hydroponic plants**

What must be done is to minimize or suppress the growth of moss. Things that can be done include cleaning gutters after each harvest. Cleaning the nursery gutters every time the seedlings move to the gutters (if the seedlings are growing using gutters). Drain and provide shade or cover on the reservoir. Using reservoirs and hoses that do not penetrate the sun. Minimize the gaps where sunlight enters the gutter.

Here we share tips that we do in our garden:


Another part that likes to be overgrown with moss is in the paragon pipes around the plant roots. The sun's rays penetrate the gaps between the net pot and the PVC pipe, stimulating the growth of moss. For this one, the growth of moss can be overcome by doing regular cleaning.

To overcome the problem of moss growth in Cirebon, West Java, we use H2O2. The benefit of this H2O2 is an anti-microbial that is safe from the recommendations of the FDA (United States Food and Drug Administration).

Some of the benefits of H2O2 for hydroponic plants:

1.prevent root rot.


4.Sprayed on the stems and leaves to eradicate the fungus.

5.Treating wounds or damaged parts of plants.

H2O2can supply extra oxygen to plant roots, so the absorption of nutrients to the roots will be maximized, when plants get enough nutrients, growth will be faster, healthier, and also stronger against pests. In water for hydroponics, you can use the dose of 2 ml H2O2/liter water, first while looking at the condition of the plants because if there are too many hydroponic plants, they can wither.

The second way to deal with moss we use an ultraviolet lamp (**Figure 4**).

The benefit of UV light, the nutrients needed by hydroponic plants are maintained and get enough light for a full 24 hours so that plants grow more optimally. The rapid growth of 24-hour plants will beat the growth of moss so that moss disturbances can be overcome using an ultraviolet lamp. With a stable irrigation system and lighting with UV lamps, organic vegetables can be harvested in just 30–35 days, faster than the normal 45 days. In terms of weight, it can reach 200–250 grams for each plant stem. Certainly heavier than ordinary hydroponics which

usually only reaches 150 grams per plant stem. In terms of quality, plants that use a hydroponic system with a UV light have brighter leaves, bright white roots. This is an indicator that the plant is growing healthily. (**Figure 5**)
