Description. 100% brand new and high quality. How to grow seeds: Sprinkle evenly on the surface of the mud or sand, spray with water to moisten the seeds and after five minutes, add some water along the wall of the tank to soak them or fill them up with water. Seed germination time: In summer, at a temperature of 28-33 degrees with plenty of light, the seeds will germinate in the water in about 7 days. In winter, at 15-20 degrees with sufficient light, seeds germinate in water in 10-15 days, but you can use a heating rod to shorten the germination time. In winter, at temperatures below 8C, seeds are dormant and germination time is to be determined. Caution: Remember not to wait for all the seeds to grow before adding water, as this will cause the seeds to rot in the water. (The principle is the same as turning leaves to water on water, if it works, it works, if it doesn't, it rots ) Product includes. 1* fish tank plant seeds (No box, no accessories other than the product included!)
