3. Operating Instructions
The Agrestem IGS-20SE is designed for ease of use with smart features to optimize plant growth.
3.1 Smart Modes: Veg & Flower
The system features two intelligent modes to provide optimal light conditions for different growth stages:
- Veg Mode: Ideal for leafy greens, herbs, and young plants. This mode provides a light spectrum that promotes vegetative growth.
- Flower Mode: Best for fruiting plants and flowering plants. This mode adjusts the light spectrum to encourage blooming and fruit production.
Simply press the corresponding button on the control panel to switch between modes.

3.2 LED Grow Light
The system is equipped with a high-performance 36W LED plant growth light with 100 lamp beads, offering 5 colors of full spectrum light. This simulates natural sunlight, accelerating plant growth up to 5 times faster than traditional soil gardening.

3.3 Automatic Timer
The integrated automatic timer ensures your plants receive the right amount of light daily. The light operates on a 16-hour ON and 8-hour OFF cycle, mimicking natural day-night patterns for healthy plant development.

3.4 Automatic Watering System
The 5L large water tank and automatic water circulation system ensure plants are evenly irrigated. A noise-reduction pump increases oxygen in the water, promoting stronger root development and overall plant health.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your Agrestem Hydroponic Growing System.
- Water Level: Regularly check the water level display and refill the tank with fresh water and nutrient solution as needed. Do not let the water level drop below the minimum mark.
- Nutrient Replenishment: Follow the nutrient solution instructions for proper dosage and frequency. Typically, nutrients should be replenished every 1-2 weeks, or when the water is refilled.
- Cleaning: Periodically clean the water tank and pump to prevent algae buildup and ensure proper water circulation. Disconnect power before cleaning. Use a soft brush or cloth and mild soap if necessary, then rinse thoroughly.
- Pruning: Prune your plants regularly to encourage bushier growth and prevent overcrowding, which can improve air circulation and light exposure.
- Replacing Grow Sponges: After harvesting, replace old grow sponges with new ones for your next planting cycle.
5. Troubleshooting
If you encounter any issues with your Agrestem Hydroponic Growing System, refer to the common problems and solutions below:
| Problem | Possible Cause | Solution |
|---|---|---|
| Plants not growing or slow growth | Insufficient light, incorrect nutrient levels, old seeds, improper temperature. | Ensure light is at correct height and mode. Check and adjust nutrient solution. Use fresh, viable seeds. Maintain room temperature between 68-78°F (20-25°C). |
| Algae growth in water tank | Excess light exposure to water, high water temperature. | Ensure grow baskets are properly covered. Clean the tank thoroughly. Consider placing the system in a cooler area. |
| Pump not circulating water | Pump clogged, low water level, power issue. | Check water level and refill. Disconnect power and clean the pump. Ensure power adapter is securely connected. |
| Leaves turning yellow or brown | Nutrient deficiency/excess, pH imbalance, overwatering/underwatering. | Check nutrient solution concentration and pH. Ensure water level is maintained correctly. Consult plant-specific guides for optimal conditions. |
