A bright window is enough, unless you grow during the winter in Scandinavia/Northern America. Don’t use incandescent light bulbs. Use fluorescent lamps, either as light bulbs or as tubes.

LED is also good, but it’s not at all necessary to use the red and blue ones that are called “grow lights”. White light is just fine. Make sure you get a 10 W LED lamp, at least, and put it at 15 cm distance. Plants love to get lots of light. Let it be powered on for 12 hours per day.

The growing medium is made of Light Expanded Clay Aggregate, also called LECA. It is a very porous medium that retains air as well as moisture, which makes it a great medium for roots to grow in.

The nutrients included in the kit will last for at least 5-6 months. You can buy more nutrients from our web shop or your preferred gardening store. Ask for hydroponic nutrients, since normal fertilizer is intended for soil.

Only about 5 mW in average during a day. Since the pump is controlled by a timer, and only is active for a few minutes per day, it uses very little power.

Not on the Botanium - the watering schedule is designed to work with all plants. The excess water is collected and reused, so the plant can never be overwatered.

Botanium Vega has the option to water more often, to cater for very thirsty plants.

It really depends. Some power banks will shut down when the consumption is less than certain threshold.

The growing medium basically lasts forever! However, if you have grown something and want to start over with a new seed, it is recommended to get new medium, as the roots will be very entangled in it. You can buy new growing medium on our webshop.

Yes, simply pull out the plant from the growing container and replant it.
