Moisture Absorption Capacity
1. Basic Adsorption Performance
Our potted plants silica gel is a porous silica material. Its open pore structure can absorb 30%~40% of its own weight in water. Through dynamic absorption and release of water, it can reduce soil moisture fluctuations, and significantly reduce the frequency of watering. For example, even if there are 7-10 days on a business trip, the potted plants can still remain active.
2. Humidity Dependence Characteristics
- When relative humidity is 20%: moisture absorption ≥ 10%.
- When relative humidity is 80%: moisture absorption ≥ 35%
- Under saturated conditions of 100% humidity, moisture absorption can reach 40%.
3. Temperature Influence
- The optimal temperature range is 21°C–32°C;
- The moisture absorption efficiency decreases significantly at 38°C.
4. Humidity Control Effect
Even if the ambient humidity reaches 60%~90%, this silica gel desiccant can still stabilize the humidity in the potted container at 40%, preventing the soil from being too wet.
5. Compared With Other Materials
This silica gel absorbs much more water than traditional water-absorbing materials, such as calcium oxide (CaO) and magnesium oxide (MgO). And it remains highly efficient after repeated use.
Product Features and Advantages
1. This potted plants silica gel can lock moisture firmly. At the same time, when the soil is dry, the moisture can be released slowly, effectively extending the watering interval.
2. The particle structure can effectively improve soil compaction, increase soil porosity, and promote air circulation.
3. Avoid water accumulation. It can greatly reduce the risk of root suffocation and rot due to excessive watering, and make the root system healthier and stronger.
4. It will not change the original pH value of the soil, and gently care for the plant roots.
5. Potted plants silica gel with lightweight texture. It effectively reduces the overall weight of the potted plant. It is easy to move and hang.
