Frequently Asked Questions

Nature has its own timing and ways of doing things. We recommend reading up a little on the seeds, especially if you intend to use your own seeds, to understand more their growth requirements. Eg. their germination period, required temperature for germination, etc.

Of course, we will be more than delighted to answer your questions and you can hit us up on Facebook.


Where should Plantui Smart Garden™ be placed? You can place your Plantui Smart Garden™ almost anywhere in your home. Plantui Smart Garden™ does not need sunlight, and it can be therefore placed in your hallway, bedroom, kitchen, bathroom or wherever you might find it suitable. It is not recommended to place Plantui Smart Garden™ under direct sunlight, as the Light Unit™ is already providing the plants with the exact amount of light they need. Too much sunlight could cause the plants to dry out. Also it's not recommended to place Plantui Smart Garden™ near radiators or air-conditioning equipment. Plants don't like draught or dry air.
Can Plantui Smart Garden™ be placed outdoors? No, Plantui Smart Garden™ is designed for indoor use. It is not resistant to sunlight, harsh temperature changes or rain.
Washing Plantui Smart Garden™ We recommend washing the components of the devices after each harvest (app every 6-12 weeks). The bowl, the water tray and the plant tray are all dishwasher safe (max 55 °C).

Water and Nutrients

 When to add water? When you begin the germination process with a Plantui 6, you must add 3 liters of water and 3 Plantui spoonfuls of plant nutrients. This amound will last for a few weeks (depending on the plant type). The Light Unit™ will blink blue (as a sign of warning) and thus signal that it is time to add more water and nutrients. Later you will have to add water about once a week. When you add water, always remember to mix Plantui nutrients (1 spoonful of nutrients to 1 liter of water) with it.
How much should I add water when the lights turn blue?  You can add 2 liters of water with 2 spoonfuls of Plantui nutrients mixed to it.
What amount of Plantui Nutrients™ should be added? The measuring ratio is always 1 Plantui spoonfuls Plantui nutrients to 1 liter of water.
Do nutrients always have to be added in the water? Yes, Plantui nutrients should be always added when adding water. Nutrients are necessary for the plants' growth process.
Can other types of nutrients be used? No, the nutrients for the Plantui Smart Garden™ are specifically designed for the intelligent irrigation system of this hydroponic device. Other forms of nutrients require soil in order to function optimally, and they can be detrimental to the water pump in the Plantui Smart Garden™. The use of other nutrients in Plantui Smart Garden™ affects the 2-year warranty of the device. The warranty is only valid if you use Plantui nutrients as we have described in the instructions.
My dog drank the water with nutrients. What should I do?  The nutrients are of course not intended for humans or animals, but for plants. However, nothing will happen if your dog has been drinking from the water tank. The nutrients mixed with water are not dangerous, as all the ingredients of the nutrients are natural. Due to the added nutrients, the water becomes salty, similar to salt water.
What do Plantui Nutrients™ contain? Plantui nutrients are made exclusively of natural ingredients. Our nutrient mix consist only of the essential nutrients plants need (nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, zinc, boron, copper and molybdenum). Read more here: http://plantui.com/feeding-your-plants-plantui-nutrient-mix/
Does Plantui function as an air humidifier? No, that cannot really be said. Plantui Smart Garden™ is a closed ecosystem, but plant are evaporating water, which is good for the indoor climate.
Can I use the same nutrient for all plants? Yes, you can use the Plantui nutrient with all Plantui plants. We have carefully chosen the nutrient to fit the needs of all the plants that we have in our selection.
Are the nutrients organic? Our nutrient mix consist only of the essential nutrients plants need (nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, zinc, boron, copper and molybdenum). These nutrients come from the nature: either from the air or through mining. In hydroponics, such as Plantui Smart Garden, all of the essential nutrients are added into water. Organic fertilizers cannot be used in hydroponic gardening, because the organic fertilizers need special soil-bound bacteria to break down the organic compounds into inorganic substances plants can consume. There’s no soil-bound bacteria in pure hydroponic gardening, like the Plantui Smart Garden. That's why we give the nutrients to the plants in the form they can directly use.

Plants and Plant Capsules

Where / how should I store my Plantui Plant Capsules? Plantui Plant Capsules should be stored in a cool, dry and dark place. Cool room temperature is good, but refrigerator is even better. If you have opened a package, close it well because the seeds might get damaged by air humidity.
How long does it take for plants to grow? Plants differ in their growth process, the germination phase thus varies from plant to plant, but on average plants will germinate between 4 days to 2 weeks after planting. The fastest plants are ready to be harvested after four weeks. We recommend to harvest the plants 2-3 months after sowing at the latest. Then you can plant new Plantui Plant Capsules™. You can see the specific growth timeline of each plant on http://plantui.com/plant-capsules/
When can I start eating the herbs and salads? The information on when to start consuming herbs and salads (Harvesting) is indicated on each Plant Capsule™ package. You can see the harvesting time in the growth timeline of each plant on http://plantui.com/plant-capsules/
What parts of the plant can I eat? On a general basis, both the leaves and stems of a plant are edible. In edible flowers the flowers can of course be eaten, but if a herb starts to produce flowers, they are edible too.
Can I replant the plants from a Plantui Smart Garden™ on the balcony or outdoors in the yard? You can of course replant the sprouts in soil, but you should be aware that they can be very delicate at the beginning. The roots and the capsule should be covered with soil. The seedling need air and light. The plants are not used to natural light, and thus need to be covered during the first few days in order to get their roots deep enough in the soil. The plants from a Plantui Smart Garden™ are used to living under optimal, but quite different lightning conditions and receiving water from an intelligent irrigation system, hence switching to soil can be a big challenge for them.
Can I buy extra capsules without seeds? Yes, you can buy the Experimental Kit: https://plantui.sg/collections/advanced/products/experiment-kit.  It includes 3 empty Plant capsules and Plantui nutrients.
My dog ate a plant capsule. What should I do? You should treat your dog as if they have eaten soil or peat.
Where can I dispose of the Plantui Plant Capsules™ Plantui Plant Capsules™ are made of Lava stone (Basalt) wool, which does not decompose. You can dispose of them in your normal household garbage. If you prefer recycling, you can mix the content of used plant capsules with soil. They improve the physical quality of soil.
There are insects in my plants. What should I do? Plantui Plant Capsules™ are made of pure Lava stone wool, which does not bring any insects with it. If you find insects in your plants, they have spread from other plants or from outside. Harvest your plants and clean your device well. Take a few days break in growing and then start again with new Plant Capsules.
Can Plantui Smart Garden™ spread bacteria in the air? No, Plantui Smart Garden™ contains no soil, and will therefore not spread mold spores or soil bacteria in the air. However, Plantui Smart Garden™ should be cleaned after each harvest (approximately every 2 or 3 months), so new plants will get a fresh start in a clean device.
How long do the herbs keep after harvesting? You can eat your salads and herbs for about a week after you have harvested them, if they are kept in an airtight environment in a refrigerator. Flowers should be used during the same day. You can also dry or freeze both your herbs and edible flowers for later use.
Can plants cause allergic reactions? No, it is safe to eat all our plants, unless you are already allergic to certain herbs or plants.
Can I plant my favourite flowers in the Plantui Smart Garden™ You can plant your personal favorites in your Plantui Smart Garden™ by using the empty capsules of the Experimental Kit (https://plantui.sg/collections/advanced/products/experiment-kit). When you plant your own seeds in a Plantui Smart Garden™, you do it at your own risk, because not all plants grow well in hydroponic indoor gardening. Feel free to experiment! If you want to be sure that the growing is successful, you can use Plantui Plant Capsules™ (http://plantui.com/plant-capsules/).
Can I only grow one type of plant at a time in the Plantui Smart Garden™? No, you can grow different types of plants at the same time. Some plants grow slower, some faster, the plants with similar growth rhythm should be grown together. Please check the growing times of each plant by viewing its details on http://plantui.com/plant-capsules/
Why is lava stone wool used as s substrate? The Plantui Plant Capsules ™ are made of lava stone wool in order to ensure optimal water and oxygen levels for the plants. The rockwool capsule supports the plants when their roots grow to the nutrient solution.
Does the level of calcium in water affect the plants and the device? The level of calcium in water is usually not a problem for the Plantui Smart Garden™: the plants will take the right amount of calcium according to their needs, and the pump of the device will not be affected since the mechanism for the water circulation prevents calcium residues. However, very high calcium levels in the tap water can partly block the pump or make visible traces on the plastic parts. Plantui 6 Smart Garden™ has an auto descaling mode to solve that problem. Add 1 tablespoon (15 ml) of citric acid with 3 liters of warm water (max 55 °C) in the water bowl of an empty Plantui 6 Smart Garden. Hold your hand on the top of the device for 15 secs until the lights turn blue. The pump will operate for 2,5 min. If necessary, leave it to soak for a few hours and restart the pump. Then wash the parts (max 55 °C).
How do I take care of my basil and make it more bushy? Three weeks after sowing (or when the plants are big enough), pinch off the top of the plant. You can do it with a pair of scissors or by hand by cutting off the growing point (the small leaves at the top) so that about two pairs of leaves are left below. The plant will then start growing lateral shoots at the base of these leaves, which makes it more bushy.​ Read more here: http://plantui.com/get-fingers-green-pinch-grow/
Are the seeds organic? Plantui seeds are not produced organically, but the seeds are inspected, all natural (no GMO), and have not been treated using any chemicals.
What is the green/black thing on the capsule? Why is it there? Does it bother the plants? Sometimes there can be algae growing on the capsule. It appears always when there's enough light, moisture and nutrients. Normally the plants grow so quickly that they shade the capsule before the algae appears. If the plants are quite slow to grow, the algae can grow on the capsule, but that doesn't harm the plants.
