Description
The LetPot Max Smart Indoor Hydroponic Garden is the most advanced and premium system in the LetPot range. Designed for growers who want maximum convenience and consistent results, LetPot Max fully automates the entire growing process — from watering and nutrient delivery to lighting and growth cycles — so your plants thrive with minimal hands-on care.
Whether you’re cooking daily, managing a busy schedule, or travelling, LetPot Max keeps herbs and vegetables growing steadily in the background. You’ll always return to fresh, ready-to-pick ingredients that elevate everyday meals and make home cooking more enjoyable.
Fully Automated Indoor Growing
LetPot Max takes smart gardening to the next level by removing the most common maintenance tasks. The system automatically manages water levels, nutrient dosing, and light schedules, creating stable growing conditions that support healthy growth and reliable harvests year-round.
Automatic Water Refilling
LetPot Max introduces a seamless connection to an external water tank for automatic water replenishment. This ensures your indoor garden stays hydrated without constant monitoring, making it ideal for longer absences, holidays, or simply reducing day-to-day maintenance.
Automatic Nutrient Addition
As the first LetPot system with an integrated auto-nurturing function, Max automatically dispenses nutrients after each water refill. This removes the guesswork from feeding plants and helps maintain optimal nutrient levels throughout the entire growth cycle.
Expanded Plant Capacity for Larger Crops
With its high-capacity layout and the addition of a larger 2-hole tray, LetPot Max supports both dense planting and bigger plants that need more room to develop. This makes it especially well suited for growing fruiting and taller crops such as tomatoes and chilli peppers, alongside herbs and leafy greens.
Convenient Smart Control
Control and monitor your LetPot Max effortlessly using the built-in 4.6″ LED touch screen or through the mobile app. Adjust settings, check system status, and enjoy peace of mind knowing your garden is running smoothly — even when you’re away from home.
What You Can Grow
Using our curated IndoorGarden seed selection, LetPot Max supports a wide range of indoor crops, including:
- Herbs such as Basil, Parsley, Coriander, Dill, and Chives
- Leafy greens like Lettuce and Spinach for frequent harvests
- Fruiting and taller plants such as Cherry Tomatoes and Chilli Peppers

If you don’t need full automation or want a more compact setup, the LetPot Mini 5-Pod Smart Garden is a great entry-level option for small kitchens, while the LetPot Air 10-Pod Smart Garden offers more growing space with smart features at a more accessible price point. For growers who want premium finish and support for taller plants without full automation, the LetPot Senior 12-Pod Smart Garden is an excellent middle ground.

The built-in pump circulates water and nutrients evenly to roots, keeps the reservoir oxygenated, and prevents stagnation for healthier, faster growth. - How often do I need to refill?
