Prêt à Pousser’s Nano grows one plant at a time from a closed, proprietary seed capsule controlled through a Bluetooth app, while Botanium’s single pot takes any seed and holds its 1-litre reservoir for several weeks between refills. Prêt à Pousser lists the Nano at €79, and Botanium’s pot sells at IndoorGarden for €69.
Both are single-plant hydroponic pots aimed at a kitchen counter or a desk rather than a full herb rotation, and both come from European design studios rather than the usual American smart-garden names. This guide lines up what each one actually does: how watering and feeding work, whether you can sow your own seed, how big each pot is, and what it costs to buy and keep running.

What each pot actually is
Botanium is a Swedish-designed single-plant hydroponic pot that won a Good Design Award in Japan in 2021, built around a 1-litre water reservoir and USB-powered automatic watering, with the grow light sold as a separate accessory. Prêt à Pousser is a French brand whose Nano model pairs a water vase with a floating seed capsule and a built-in LED bar, connected to a companion app over Bluetooth so you can follow the plant’s growth stages on your phone, according to French tech outlet Clubic. Both are built for one plant at a time rather than a multi-pod tray, which puts them in a different category from a 5-pod or 12-pod smart garden.
Watering and feeding: a reservoir vs a float
Botanium’s approach is the simpler of the two to describe: a 1-litre tank feeds the roots automatically, and the manufacturer says a full tank typically lasts several weeks before it needs topping up, which suits anyone who travels or just does not want a daily task. Prêt à Pousser’s Nano uses a patented float design instead, where the seed capsule sits on a floater that sinks gradually as the plant draws down the water level, and Clubic reports the tank typically needs refilling every 7 to 10 days. Neither system asks you to mix or measure a nutrient solution yourself: Botanium ships a pipette bottle of liquid nutrients with the pot, and Prêt à Pousser’s capsules already include their own nutrient charge.
Seeds: open sponge vs closed capsule
This is the single biggest practical difference between the two. Botanium’s product listing states plainly that it works with any seed in its growing medium rather than a locked pod, so a saved tomato seed or a supermarket herb packet works the same as a seed bought from the brand. Prêt à Pousser’s Nano runs on proprietary capsules instead, and Clubic’s review counted 74 capsule varieties in the catalogue at the time of writing, including one sold without seed for growers who want to start their own. That openness is also why Botanium’s running cost stays low once the pot is bought: a fresh seed packet costs a few euros, while each Prêt à Pousser replanting means ordering another capsule from the brand’s own range.
Size, light and where each one fits
Botanium is the more compact of the two at 136 × 250 mm, built to sit on a narrow windowsill or a shelf, and its grow light is a separate 15 W full-spectrum E27 lamp you add only if the spot does not already get enough daylight. Prêt à Pousser’s Nano measures roughly 45.4 × 13.5 × 10.5 cm and weighs under a kilogram without water, with its light built in as a bar of 12 LEDs rated at 2.5 W, controlled on and off automatically through the app as the plant moves through its growth cycle. Both are light enough to move between a kitchen counter and a desk without any tools.
Price, warranty and buying in the EU
Botanium is sold at IndoorGarden for €69, reduced from a regular €75, and like every product we sell it ships from our Tallinn warehouse with a 2-year EU warranty and spare parts available without a customs wait. Prêt à Pousser lists the Nano at €79 through its own channels and is also carried by general EU electronics retailers, though stock and pricing on those listings varies and delivery timing is shown at checkout rather than fixed in advance. Neither brand publishes a running-cost figure for electricity, but at 2.5 W and 15 W respectively, both lights cost only a small fraction of a typical EU household’s monthly bill even run for several hours a day.

Frequently asked questions
Can I use my own seeds in a Prêt à Pousser Nano?
Only with the capsule sold without seed, since the Nano is built around proprietary capsules rather than an open growing sponge. Botanium is the better fit if sowing your own seed matters to you, since it is designed to take any seed from the start.
Which pot is cheaper to keep running?
Botanium, in most cases. A fresh seed packet costs a few euros and lasts one growing cycle, while each Prêt à Pousser replanting means buying another capsule from the brand’s own catalogue, which adds up over several cycles a year.
Does either pot need daily attention?
No. Botanium’s 1-litre tank is built to last several weeks between refills, and Prêt à Pousser’s float design typically needs topping up every 7 to 10 days, so both are built around a check every week or two rather than daily watering.
Can I grow a tomato or chilli in either pot?
Both are sized for one compact plant, so a dwarf or determinate variety is the realistic choice in either, and the capsule catalogue for the Nano does include some mini vegetable varieties. For a plant that needs to grow much taller, a multi-pod smart garden with more grow height suits better than either single pot.
Is Botanium available with EU warranty support?
Yes. Every Botanium we sell ships from our Tallinn warehouse with a 2-year EU warranty, and spare parts and accessories such as the grow light arrive the same way, without a customs wait.
Does the Prêt à Pousser Nano need an app to work?
The Bluetooth app handles capsule selection and shows growth-stage reminders, so it is part of normal use rather than optional, which is worth knowing if you would rather not tie a plant pot to a phone app.
Where to start
If sowing your own seed and a low running cost matter most, the Botanium smart hydroponic pot is the simpler long-term choice, and it sits well alongside our wider mini smart gardens range if you later want more than one plant running. If a closed, app-guided capsule system appeals more than open seed, the Nano is worth a look through its own retailers. Either way, our Click & Grow alternatives comparison covers more multi-pod options if one plant is not enough.
