Click & Grow Smart Garden 9 Pro Review: The Ultimate Indoor Garden for Smart Home Enthusiasts

Product Overview: What Is the Click & Grow Smart Garden 9 Pro?

The Click & Grow Smart Garden 9 Pro is the flagship model in Click & Grow's lineup of indoor smart gardens. It is designed to grow up to nine plants simultaneously using the company's proprietary plant pod system. Unlike its predecessor, the standard Smart Garden 9, the Pro model adds Wi-Fi connectivity, app-based monitoring and control, adjustable grow light arms, and a larger water tank for extended autonomy.

At its core, the system uses Click & Grow's patented Smart Soil technology — a nano-tech growing medium that automatically releases oxygen, water, and nutrients to plant roots based on their needs. This eliminates the need for manual fertilization, pH balancing, or complicated hydroponic setups. The garden features a full-spectrum LED grow light panel that simulates sunlight, with an automatic timer that runs on a 16-hour-on, 8-hour-off cycle by default.

Design & Build Quality

The first thing you notice when unboxing the Click & Grow Smart Garden 9 Pro is its clean, minimalist aesthetic. The unit features a matte white plastic base with a matching white light arm and LED panel. The design language is unmistakably Scandinavian — functional, unobtrusive, and intended to blend into modern kitchen or living room decor rather than dominate it.

Materials and Construction

The body is constructed from UV-stabilized ABS plastic, which resists yellowing over time even with constant exposure to the grow lights. The water reservoir is integrated into the base and features a transparent water level indicator on the side, allowing you to check water levels at a glance without opening the unit. The light arm uses a telescoping mechanism that extends smoothly and locks into place at various heights, accommodating plants from seedling stage through full maturity.

One notable design improvement in the Pro model is the adjustable light arm extension. The standard Smart Garden 9 has a fixed-height light bar, which can lead to light burn on taller plants or insufficient light intensity for shorter ones. The Pro's adjustable arm solves this elegantly, letting you raise the light panel as plants grow. Independent testing shows that maintaining a 5-10 cm distance between the light source and plant canopy optimizes photosynthetic efficiency, and the Pro makes this easy to achieve.

Water System and Smart Soil

The 4-liter water tank is a significant upgrade over smaller Click & Grow models. In our testing, the tank provided approximately 3-4 weeks of autonomy for mature herbs like basil and mint, and up to 5 weeks for slower-growing plants like thyme. The wicking system that draws water from the reservoir into the Smart Soil pods is entirely passive — no pumps, no noise, and no moving parts to fail.

The Smart Soil pods themselves are a marvel of materials engineering. Each pod contains a pre-measured amount of nutrients, a pH-buffered growing medium, and seeds embedded at the optimal depth. You simply drop the pod into its cup, add water to the reservoir, and the system handles the rest. Click & Grow states that their Smart Soil technology is based on NASA-inspired growing methods, and the results largely support this claim.

Performance & Plant Growth Results

The most critical question for any indoor garden is simple: how well do plants actually grow? We tested the Click & Grow Smart Garden 9 Pro over a 90-day cycle using a mix of herb pods (basil, cilantro, parsley), leafy greens (lettuce, kale), and one experimental fruiting plant (mini tomato).

Germination and Early Growth (Days 1-14)

Germination rates were impressive across the board. Basil sprouted within 5-7 days, cilantro within 7-10 days, and lettuce within 4-6 days. The parsley took the longest at approximately 12-14 days, which is consistent with its natural germination timeline. The mini tomato emerged around day 10. Overall germination success rate was 9 out of 9 pods — a 100% success rate in our test cycle.

The consistent moisture delivery from the Smart Soil and the stable light environment clearly create ideal germination conditions. We noticed no mold growth on the soil surface, which can be a common issue with other indoor gardens that over-water or lack adequate air circulation.

Vegetative Growth Phase (Days 15-45)

During the vegetative phase, the Smart Garden 9 Pro truly showed its capabilities. Basil plants reached harvestable size (approximately 15 cm tall with multiple leaf sets) by day 25, which is notably faster than soil-based indoor growing. Lettuce was ready for its first "cut-and-come-again" harvest by day 30. The LED light panel delivered even coverage across all nine pod positions, with no noticeable difference in growth rates between center and edge pods.

The adjustable light arm proved essential during this phase. As the basil and tomato plants grew taller, we raised the light panel in 5 cm increments to maintain optimal light distance. Plants that received consistent 16-hour light cycles showed approximately 20-30% more biomass compared to manufacturer data from shorter photoperiods.

Mature Growth and Harvesting (Days 45-90)

By day 45, the basil plants were producing enough foliage for weekly harvesting. The lettuce continued producing new leaves after each cutting, and the kale developed robust, dark green leaves. The mini tomato plant began flowering around day 50, and we observed the first small fruits by day 65.

One limitation we noted: fruiting plants like tomatoes require pollination, and the enclosed indoor environment means you need to manually pollinate flowers using a small brush or by gently shaking the plant. Click & Grow's app provides reminders and instructions for this, but it is an extra step that pure herb growers will not need to worry about.

Light Quality and Energy Consumption

The full-spectrum LED panel produces light in the 400-700 nm PAR (Photosynthetically Active Radiation) range, which covers the wavelengths plants need for photosynthesis. The light output of approximately 1200 lumens is sufficient for herbs and leafy greens but may be marginal for heavy-fruiting plants. In our testing, the mini tomatoes produced fruit but at a slower rate and smaller size compared to greenhouse-grown counterparts.

Energy consumption averaged 13 watts during light-on periods, translating to approximately 6.2 kWh per month based on a 16-hour daily cycle. At average electricity rates, this adds roughly $0.75-$1.25 per month to your utility bill — a negligible cost for year-round fresh produce.

Setup Experience & App Integration

One of the Click & Grow Smart Garden 9 Pro's strongest selling points is how easy it is to get started. The entire setup process — from unboxing to planted garden — took us under 15 minutes.

Physical Setup

The box includes the garden base, light arm, LED panel, power adapter, and nine plant pods of your choice (depending on the bundle you purchase). Assembly involves three steps: click the light arm into the base, plug in the power adapter, and insert the plant pods into their cups. Fill the water reservoir until the indicator shows full, and you are done. There are no tools required, no plumbing, and no complicated calibration.

App Setup and Wi-Fi Connectivity

The Click & Grow app (available on iOS and Android) handles the smart features of the Pro model. After downloading the app and creating an account, you add the garden via Bluetooth pairing, then connect it to your 2.4 GHz Wi-Fi network. The setup process was straightforward in our testing, completing in under 3 minutes. One caveat: the system only supports 2.4 GHz Wi-Fi, not 5 GHz, which is common for IoT devices but may require you to adjust your router settings if you run separate network bands.

Once connected, the app provides a dashboard showing your garden's status, including water level alerts, light schedule, and a plant growth timeline. You can customize the light schedule (the default 16/8 cycle works well for most plants), set vacation modes, and receive push notifications when the water tank needs refilling.

Smart Features and Automation

The app includes a "Plant Library" with growing tips, harvest timelines, and care instructions for each pod variety. It tracks the age of your plants and sends reminders when they are ready for harvest or when pods should be replaced (most pods are productive for 2-5 months depending on the plant type).

While the app is functional and well-designed, we noted a few areas for improvement. There is no integration with third-party plant tracking tools, and the data export options are limited. The app also does not provide detailed light intensity metrics or historical growth data beyond basic timeline markers. For users who want granular data about their garden's performance, these omissions may be noticeable.

Ecosystem Compatibility & Smart Home Integration

For smart home enthusiasts, ecosystem compatibility is a crucial consideration. The Click & Grow Smart Garden 9 Pro operates primarily within its own app ecosystem, and its integration with broader smart home platforms is currently limited.

Current Smart Home Support

As of our testing, the Smart Garden 9 Pro does not natively support Amazon Alexa, Google Home, Apple HomeKit, or Samsung SmartThings. All control and monitoring must be done through the Click & Grow app. This is a notable gap compared to some competing smart gardens that offer voice control and scene integration.

However, there are workarounds for advanced users. The garden's consistent power draw pattern makes it compatible with smart plug-based automation. By connecting the garden to a smart plug (such as those from TP-Link Kasa or Eve Energy), you can integrate it into broader routines — for example, turning the garden light off when you leave home or syncing it with your morning routine. This does not give you app-level control over water monitoring, but it does allow light schedule integration.

Click & Grow Ecosystem

Within the Click & Grow ecosystem, the Pro model integrates seamlessly with other Click & Grow products. If you own multiple gardens (such as the Smart Garden 3 or the larger Smart Garden 27), the app manages all devices from a single dashboard. The plant pod system is also cross-compatible across all Click & Grow garden sizes, giving you flexibility to experiment with different plant varieties.

The company has indicated that broader smart home integrations are on their development roadmap, but no firm timeline has been announced. For users building a comprehensive smart home setup, this limited integration may be a deciding factor. Browse our smart home ecosystem comparison guide to see how different platforms stack up.
