Two systems, same price, completely different philosophies about what indoor gardening should feel like. If you’re trying to decide between the LetPot LPH-SE vs Click and Grow Smart Garden 9, the technology gap between them is enormous despite the identical price tags. The LetPot LPH-SE buy on Amazon runs an aeroponic pump, connects to WiFi, and gives you 12 pods with a shared nutrient solution. The Click & Grow Smart Garden 9 check current price has no pump, no app, no nutrient mixing, and 9 self-contained pods that each feed themselves from pre-loaded smart soil. Both land around $99-120.
So which one is actually worth your counter space? That depends almost entirely on what you’re trying to grow and whether you ever plan to take those plants outside. I’ll break down both systems honestly, including the parts that nobody in the comparison space seems to want to say plainly.
Quick Answer: For outdoor gardeners who want to start seeds indoors and transplant outside in spring, get the Click & Grow Smart Garden 9. The enclosed pods protect roots during transplant and the zero-maintenance setup is hands-off. For serious indoor herb production year-round, get the LetPot LPH-SE, it grows faster, produces more over time, and gives you 12 pods instead of 9. The tradeoff is biweekly nutrient dosing, pH awareness, and an app that may or may not cooperate.

The Core Tech Difference Matters More Than You’d Think
Click & Grow uses passive wick hydroponics. A cotton wick at the base of each pod cup pulls water up from the reservoir to the roots. The smart soil has nutrients pre-embedded, so each pod is self-contained. This is why you can grow basil next to cherry tomatoes next to wild strawberries without conflict, those plants never share a nutrient solution. Each pod feeds itself.
LetPot uses an aeroponic pump that circulates and mists the water on a timed cycle. All 12 pods pull from the same reservoir. That’s where the complication starts: if you want to grow basil alongside tomatoes, you’re asking plants with different nutrient and pH preferences to share the same water. Basil likes EC around 1.0-1.4. Tomatoes want much higher concentrations when they start fruiting. One of them will be compromised.
I’ve written about this shared-reservoir problem before, it’s why grouping herbs by compatibility matters in any aeroponic pod system.
For a pure herb rotation with similar plants, basil, cilantro, mint, dill, the shared reservoir is fine. But if your outdoor gardening habit has you wanting to mix tomatoes, peppers, herbs, and greens all at once, Click & Grow is the more flexible system here. That’s not a minor point.
Transplanting: The Outdoor Gardener’s Deciding Factor
This is the question nobody’s answering in existing comparison articles, and it’s the one that matters most if you’re reading this in January thinking about your May garden.
Click & Grow pods keep roots contained inside the plastic cup throughout the grow. When you’re ready to transplant, you pop the cup out, knock the smart soil block into a hole in the ground, and plant it. The root structure stays intact. The transplant success rate is high because of this design.
LetPot’s aeroponic system lets roots grow freely into the reservoir water. After 8-10 weeks, you have a root mass that’s tangled, extended, and fragile. Extracting those roots for outdoor transplant without significant damage is difficult. It’s not impossible, but the survival rate drops compared to a contained pod system.
The common approach among growers who run both systems is to keep the Click & Grow specifically for cloning and transplanting, it tends to work well for short-term growing and anything that’s eventually headed outside, while the aeroponic system handles long-term indoor growing. That’s a sensible split if you have the counter space and budget for both.
I don’t have that luxury (two-unit maximum, firm), but if transplanting is a core part of your plan, Click & Grow wins this category outright.
Noise, Maintenance, and the Day-to-Day Reality
Click & Grow is completely silent. No pump. The water level drops slowly, you refill it, done. No nutrient mixing, no pH checking, no app. The smart soil handles everything else for about the first three months of a pod’s life. After that, the nutrients in the soil start depleting and growth slows, this is the “plateau” that comes up consistently from people who’ve run both systems long-term. It’s not a flaw, exactly, just a ceiling you’ll hit.
LetPot has a pump, which means noise. The LPH-SE is described as quiet by most owners, but “quiet” in the context of a countertop garden means you can hear it cycle if you’re in the same room. Some people don’t care. If your kitchen is separated from your living space, it’s a non-issue.
Maintenance-wise, the LetPot asks more of you. Every week or two you’re checking water levels, dosing nutrients (the A&B solution it comes with), and ideally monitoring pH if you’re growing anything beyond herbs. I’ve written in detail about why pH management matters for aeroponic systems, the short version is that Click & Grow’s smart soil handles pH regulation automatically, while LetPot leaves that entirely to you.
For an experienced outdoor gardener, this might not be intimidating. You already think about soil pH and nutrients. But you should know it’s a recurring task, not a set-it-and-forget-it situation like Click & Grow.

Check Price on AmazonThe App Question (Honest Version)
LetPot’s WiFi app integration is one of its selling points. In theory: remote light scheduling, nutrient reminders, growth tracking. In practice, the onboarding experience on the LPH-SE has a documented failure rate that nobody in the editorial comparison space is mentioning.
And honestly, this is one of the more frustrating things about recommending the LetPot LPH-SE, the app issues are specific and annoying enough that they feel like they should have been caught before launch. The app resets to the beginning when minimized mid-setup, the password has an undisclosed length cap that creates silent failures, and there’s no in-app password reset option, so if something goes wrong, you’re stuck. Support response times run around 72 hours. For a $99 device that markets WiFi control as a feature, this is irritating.
The saving grace is that the LetPot works fine without the app. The buttons on the unit control the light timer and basic functions. If you’re comfortable managing a hydroponic garden manually, the app is optional. I’d treat it as a bonus feature that might work, rather than a core selling point you can rely on.
Click & Grow needs zero digital setup. Plug it in. Add water. The light runs 16 hours on, 8 hours off automatically. That’s it. For someone who just wants herbs with no friction, this matters a lot.
I covered some of this when I compared the LetPot LPH-SE against the Spider Farmer G12 , app control is useful for multi-unit growers managing schedules remotely, but for a single kitchen garden, it’s not worth much if it doesn’t work reliably.
Long-Term Yield: Where LetPot Pulls Ahead
This is where the aeroponic system earns its extra maintenance cost. A pump circulating oxygenated water to roots grows plants faster and larger than passive wick watering. The LetPot runs a 24W LED. Click & Grow’s Smart Garden 9 spec sheet doesn’t publish wattage, but the passive system’s light is noticeably less intense, if you’re pushing herbs hard year-round, the difference shows up in stem thickness and harvest speed. Over a 6-month growing period, the LetPot will produce more harvestable herbs than the Click & Grow from the same varieties.
Click & Grow’s growth plateau is real. After the smart soil nutrients deplete, you can extend things somewhat with liquid nutrients added to the water, but the system wasn’t designed for that and results vary. It’s better suited to short-to-medium runs followed by pod replacement.
The pod cost math also goes in different directions. Click & Grow pods run roughly $3-5 each with nutrients pre-loaded, the 9-pod Smart Garden 9 bundle includes 18 pods at a price that works out to around $3 per pod, but individual variety packs price higher. That’s the cost whether you like the variety selection or not, and Click & Grow offers around 75+ varieties, decent, but you’re locked into their ecosystem. With LetPot, you’re buying blank sponges (well under $1 each in bulk) and adding your own seeds and nutrients. Over time, the LetPot’s per-pod cost is much lower if you’re willing to manage your own nutrient solution.
I track this kind of math across my countertop crop economics posts if you want to compare specific varieties.
One thing to know: Click & Grow’s light arm adjusts in height but the range is limited, it works well for compact herbs and lettuce but doesn’t give much headroom for tomatoes or peppers. LetPot’s adjustable arm goes to 30 inches, giving you real flexibility for taller crops, though again, mixing a tall fruiting plant with shorter herbs in the same aeroponic reservoir creates the nutrient compatibility problem mentioned earlier.
Electricity and Running Costs
Small difference, but real: Click & Grow’s passive system uses around 13W. An aeroponic system running a pump plus a 24W LED uses more, and LetPot’s pump cycles continuously. The annual electricity cost difference is roughly $15-20 at average US rates, in Click & Grow’s favor. But that won’t matter much to most people, and it’s worth knowing more as context than as a deciding factor.

Frequently Asked Questions
Which is better for growing herbs, LetPot LPH-SE or Click & Grow Smart Garden 9?
Depends what you mean by “better.” LetPot’s aeroponic pump produces faster growth and higher yields over a long indoor season. Click & Grow is quieter, asks nothing of you technically, and lets you mix herb varieties with completely different needs in the same unit. For serious herb production, LetPot wins on volume. For low-maintenance kitchen herbs you just want to exist and be harvestable occasionally, Click & Grow is easier.
Does LetPot work without the app?
Yes. The buttons on the unit control the light timer and basic daily functions. The common experience among those who’ve had app connectivity failures is that the LPH-SE operates normally in manual mode. The app adds remote scheduling and monitoring, but it’s not required. Given the onboarding problems, treating it as optional rather than core functionality is the right expectation to set.
Can you grow different plants at the same time in a LetPot or Click & Grow?
Click & Grow: yes, freely. Each pod feeds itself from its own smart soil, so there’s no nutrient or pH conflict between adjacent plants. You could have basil next to cherry tomatoes next to wild strawberries and each would get exactly what it needs. LetPot: technically yes, practically complicated. All pods share one reservoir, so mixing plants with different nutrient concentrations or pH preferences means one of them will be suboptimal. Herbs with similar needs work fine together; mixing herbs with fruiting plants doesn’t.
Is Click & Grow good for transplanting to an outdoor garden?
Yes, this is one of its strengths. The enclosed pod cups keep roots contained throughout the indoor grow. When you’re ready to transplant, the root structure comes out intact, and the smart soil block plants directly into outdoor soil. Aeroponic systems like LetPot let roots grow freely into the reservoir, making clean extraction for transplant much harder without damage. If your goal is starting seedlings indoors for your outdoor garden, Click & Grow’s design is purpose-built for this workflow.
What is the Click & Grow Smart Garden 9?
It’s a 9-pod indoor garden with a grow light, passive wick watering, and Click & Grow’s smart soil pods where nutrients are pre-embedded. No pump, no app, no nutrient mixing required. The light runs automatically on a 16-hour cycle. It’s about as close to zero-maintenance as an indoor garden gets, which is both its main appeal and the reason it has a growth ceiling compared to active hydroponic systems.
What’s the best indoor hydroponic garden overall?
At the $99-120 price point, the answer depends entirely on your use case. For the outdoor gardener extending their season, Click & Grow. For dedicated indoor herb production, LetPot LPH-SE or the AeroGarden Harvest. At higher budgets, the AeroGarden Bounty is the most proven system for beginners who want something that just works without fussing over compatibility.
