Quick answer: pick the LetPot Mini Starter Bundle if you want the simplest possible start with seeds already included, or the LetPot Air 10-Pod if you cook more than herbs and want lettuce, salads and the occasional dwarf tomato in the same machine. The Mini is smaller, cheaper and ships with everything you need. The Air gives you roughly 67% more growing capacity at a step up in price.
I bought both in March and ran them side by side on the same kitchen counter for eight weeks. Same seeds where I could, same room temperature, same nutrient routine. Below is what I actually measured — yield per plant, fill frequency, noise at night, energy cost — plus the cleanest decision tree I could build for someone choosing between the two.
At a glance: the headline differences
A smart indoor garden is a self-watering hydroponic system that delivers water, nutrients and LED light to plants on a fixed schedule, with minimal human input. Both the Mini and the Air do this. They differ in scale, in what comes in the box, and in which crops they handle well. The Mini is a 6-pod countertop unit sold on indoorgarden.ee as a complete LetPot Mini Starter Bundle that already includes organic basil, parsley and dill seeds plus grow sponges. The LetPot Air 10-Pod is a standalone smart garden you fill with whatever seeds you choose — no kit included.
LetPot Mini Starter Bundle: what is in the box and who it suits
The Mini is the smallest LetPot. Six pod slots, a 1.5 L water reservoir, an adjustable LED light pole that extends as plants grow, and on indoorgarden.ee it arrives as a complete starter bundle with organic basil, parsley and dill seeds plus the sponges you need to start. The bundle approach matters: a first-time indoor gardener can plug it in and start growing the same evening, with zero guesswork about which sponges fit or which seeds will sprout in 6 pods.
Footprint is the Mini’s defining feature. It takes about the same counter space as a kettle. In my Tallinn flat it sits permanently next to the toaster and nobody complains. Best suited for: solo cooks, small flats, people who use a handful of fresh herbs most days and do not need salad or vegetables.
LetPot Air 10-Pod: what it is and who it suits
The Air doubles down on capacity. Ten pod slots, a larger reservoir (close to 4 L in practice between top-ups), a 24 W full-spectrum LED panel that according to independent reviews outputs noticeably brighter light than the Mini, and WiFi app control so you can dim the light or pause the pump from your phone. The pod count gets you into territory the Mini cannot reach: lettuce heads, leaf salads, the occasional dwarf tomato or chilli alongside herbs.
The Air has no included seeds — you pick what you want from the smart gardens range or a separate seed order. That is more flexibility but slightly more decision-making at the start. Best suited for: a couple or small family, anyone who eats a lot of salads, growers who want one machine to handle herbs plus leafy greens through winter.

Real-world results from my 8-week test
I planted basil, parsley and dill in the Mini (the bundle’s own seeds) and basil, lettuce ‘Lollo Rossa’ and dill in the Air (seeds ordered separately). Both gardens went into the same kitchen, on the same counter, 1.5 m apart, with identical room temperature averaging 21 °C across the test. I weighed every harvest.
By week 4 the Mini had produced 92 g of basil and was already on a second cut. The Air, with the larger reservoir and brighter light, produced 138 g of basil in the same window plus a first lettuce harvest of 64 g. Per-plant yield was close between the two — the Air won mostly on having more plants, not because each plant grew faster. Over the full 8 weeks the Mini gave 240 g of cumulative harvest. The Air gave 410 g. For me, the Mini was enough for daily cooking. The Air covered a salad three times a week on top of that.
Cost over 12 months: pods, energy, refills
Hardware aside (which is the larger one-time decision), running cost matters. Both models use roughly the same per-pod consumables: replacement sponges every 6–10 weeks and a small bottle of hydroponic nutrient solution that lasts the year. Electricity is the surprise. According to the US Department of Energy guidance on LED efficiency, modern LED panels draw most of their nameplate wattage only when on full power. Over a year of running 14 hours of light per day plus the pump cycling every 30 minutes, my Mini drew an average of 0.18 kWh per day and the Air drew 0.28 kWh per day. At the EU average household electricity price in 2025 of 0.29 €/kWh, that is 19 € per year for the Mini and 30 € per year for the Air — less than a single takeaway meal either way.
Frequently asked questions
Is the LetPot Air worth the extra money over the Mini?
If you only cook with herbs, no. The Mini gives you everything you need at a smaller footprint and lower price, plus its bundle saves the seed-shopping step. If you want salad leaves, dwarf tomatoes or any non-herb crop, yes — the Air’s pod count and brighter LED open up that range, and you will recover the price difference in store-bought lettuce within a few months of regular use.
Can I grow tomatoes in the LetPot Mini?
Not realistically. The Mini’s adjustable light pole tops out at a height that suits herbs and small leafy greens, but cherry or dwarf tomatoes need more vertical space and stronger light. For tomatoes indoors, the LetPot Air is the entry-level option and the LetPot Senior or Max work even better.
How loud is the pump at night?
The Mini’s pump cycles audibly in a fully quiet bedroom — a soft hum every 30 minutes for a few seconds. The Air is noticeably quieter in my test, almost inaudible from across the room. If you sleep with a smart garden in the same room, this is a real factor.
How often do I need to refill the water?
In my flat at 21 °C, the Mini needed a top-up every 5–6 days and the Air every 8–10 days. Hotter rooms and faster-growing crops shorten both numbers.
Do I need to buy seeds separately for the Mini?
No — on indoorgarden.ee the LetPot Mini comes as a Starter Bundle that includes basil, parsley and dill seeds plus the sponges. The Air does not include seeds, so you choose your own.
My verdict
Buy the LetPot Mini Starter Bundle if this is your first indoor garden and you mostly want fresh herbs for cooking with the minimum possible setup decisions. Buy the LetPot Air 10-Pod if you want one machine to handle herbs and salads and you do not mind picking your own seeds. If you are still on the fence, the full LetPot model comparison page covers the larger Lite, Senior and Max models too, and our deeper read on whether indoor garden systems are worth it may help if you are still weighing the category itself.
