The Grow Block allows you to grow aromatic herbs on a wall in your home. This set allows you to build a vertical garden, without needing to drill holes in the wall. It is recommended to remove the substrate bags and seed packets. Leave the clay balls at the bottom and fill with the substrate. Open the seed packet, spread a few (15-20 seeds) on top of the substrate and bury them slightly up to half a centimeter. Save the remaining seeds for other plantings. Water or sprinkle over the seeds until moist. Place in a warm place with natural light. Spray every day to keep the substrate from drying out. When the seeds germinate (7-14 days), place them in a place with plenty of natural light and a few hours of direct sunlight a day. When the first leaves begin to appear, water lightly but without soaking. Check with your finger that the soil remains damp, otherwise water the equivalent of a coffee cup of water again.
