Begin the planting process during autumn. Get a medium-sized plant pot that has drainage holes at the bottom. Layer the bottom of the pot with small stones. Only put enough stones so that you can't see the bottom of the pot. Then, fill the pot with natural compost. Fill it up almost all the way, but leave about a 0.5 inches (1.3cm) of space at the top of the pot. Natural compost is made out of decomposing organic materials, such as leaves, hay, and raw vegetables. You can use store-bought compost if you do not have homemade compost. Once the pot has been filled with compost, dig out a small hole in the center of the pot. It should be about 0.5 inches (1.3cm) deep. Insert 2 or 3 seeds into the hole. Then, replace the compost and pat it down. After that, water the compost until it appears wet. You can put the pot outside in a shady corner, or you can put it near a window that doesn't get much light. Wherever you put it, the spot should not receive constant sunlight. Keeping the seeds at a temperature between 65F (18C) and 75F (24C). This will prevent birds and animals from eating the seeds. First figure out the circumference of the top of the pot. Use wire cutters to cut the wire mesh a little larger than the measurement you took. Then, put the wire mesh on top of the pot and fold the wire mesh over the edges. Make sure that it is secure and can't be easily removed. Check the soil daily to see if it is dry. If it is, add water to the soil. The soil should be damp but not wet. Natural germination will take longer than assisted germination. Your seeds will likely take 2 seasons to complete the germination process. If you planted the seeds in early autumn, check their progress in early spring. They have completed germinating if you see a small sprout growing out of each seeds.

The plastic homemade STP devices are simple to quickly rinse off. The plastic means that the any urine will bead up on the surface and be washed off easily. You can rinse it with a little soap when you are washing your hands. When you are carrying the STP device around with you, it's best to try and keep it in a small zip-lock bag. This way any unpleasant aromas or drips will be contained in the bag. If you get a small zip-lock bag, such as a freezer or sandwich bag, you will still be able to keep the STP device in your back pocket. You can also use alcohol wipes or hand sanitizer to disinfect the device after each use. You need to take extra steps to ensure that your STP device is kept clean and you limit the risk of infection.

If you already made one and stored it in the fridge, remove it so it can warm up to room temperature. If not, make a cold brew as described, but stop short of straining the liquid. Let the rice sit in the water instead and cover the bowl. Allow the rice water to ferment anywhere from 12 to 48 hours. Uncover and smell the contents periodically. Once it begins to smell sour, consider it fermented. Expect the time needed for this to vary depending on the exact temperature, plus whether or not the liquid has been strained. An unstrained mixture should ferment in 12 to 24 hours. Strained liquid will take between 24 and 48 hours. Higher room temperatures will reduce the amount of time needed. First, strain the liquid if you haven't already done so. Transfer the liquid to a pot or saucepan. Raise the heat to medium-high. Bring the water to a boil to cease the fermentation. Boiling the water after fermentation is often recommended, but not strictly required. If you intend to use it right away, allow the water to cool first to avoid scalding. Otherwise, transfer it to a sealable container. Store in the refrigerator. Expect fermented water to pack a punch. Dilute the fermented rice water with plain warm water as desired when you use it.

Each time you use a bulb syringe, you should clean it with cool soapy water. This will remove anything that may remain in the syringe after use. To do this, fill a small bowl with cool soapy water. Don't use warm or hot water because that will make it harder to remove the mucus from the bulb. Place the syringe so that it is fully submerged in the water. Leave the syringe in the water for a few minutes. Place the tip of the syringe in the water and squeeze the bulb so that the syringe fills with the soapy water. Aim the hole of the syringe in the direction of the water and squeeze the bulb to release the water down the drain. Continue to fill up the syringe with cool soapy water and then release the water. Do this three to four times in order to make sure that the inside of the syringe is completely cleaned.
