Open the water valve, wait until the fertilizer becomes relatively clear (fill about 1/3 of the bucket or the whole yellow watering can next to the container);
If needed, add some extra tap water to the plants (the soil needs to be wet but not soaking).
*Every 2 months, use 2 gram of wood ash from the rocket stove, and spread it evenly over plants (the rule of thumb is that you need to add 1 g per month; you’re adding it once every few months to make the spreading easier)
