Hydro-Gras contains water-retaining hydro-granules that eliminate the constant need for water. Instructions for use 1. It's that simple: Fill the grass bowl once up to the brim with lukewarm water. The water must be evenly distributed over the contents so that the bowl contents and the water filled therein reach the edge of the bowl. Do not pour out water! After a few minutes, the water-absorbing hydro granules have already absorbed the entire water! 2. Place the bowl in a warm place with sufficient air (eg a windowsill). Extreme heat (direct sunlight, radiator, etc.) should be avoided. 3. After 5-8 days the hydro-grass will have reached a height of about 5 cm. To keep the grass fresher for longer and to achieve full grass density, you should now distribute 1 more cup of water (approx. 150 ml) over the grass. Then you can spoil your cats with it. Tips and directions Cats need fresh greenery to supplement their diet. They often like to use house plants for this 'greenery'. However, these can be highly toxic to cats due to their content of essential oils or pesticides. Avoid that by giving your cat GimCat Hydro-Grass. GimCat Hydro-Grass provides the grass that the cat needs to spit out swallowed hair. In the cold seasons it is advisable to use, for example, a newspaper as a base, because window sills can be very cold. Metal frames also radiate cold. That is not conducive to the growth of the grass. The growth time is highly dependent on light and temperature conditions and therefore the length of growth can differ (approx. 5-8 days). Provide constant fresh grass for your cat's health and well-being. Only Hydro-Gras contains water-containing hydro-granules, so you don't have to keep adding water. Pour 1 x and the fresh grass is ready after a few days.
