Herbie FAQ

Herbie is a hydroponics device designed for indoor use. The Active Growing Technology provides nutritious, oxygenous water to the roots of the plants. Stagnant water becomes anaerobic very quickly and therefore the water circulation is crucial. In addition, the growing light with the optimal light spectrum, is an important factor for the growth.

Hydroponics has been used by professional farmers for over 40 years. Most of the 200 million herb and lettuce pots produced yearly in the Nordics are cultivated with the same principle.

Mere water is not enough for the growth of the plants, because the plants use the nutrients in pots very fast. Therefore it is recommended to use Tregren’s nutrients that are especially designed for Tregren products.

The Herbie’s sales package includes the starter pack of  nutrients. Nutrients designed for the device can be inquired at retailers selling the device. They can also be ordered through the Tregren’s store online.

The plants evaporate water and the evaporation speed depends on several factors (temperature, species etc.). The device shows also the maximum and minimum levels of the water. Water shall be added to the device when the water level goes below the minimum mark or at latest when the pump starts to take in air which is indicated by a loud sound. Typically water should be added every 2-5 days. It is recommendable to change the water at the same time as you add the nutrients. The recommendation is every 3 weeks.

The regular water change and adding the nutrient ensure successful growth of the plants also for novice gardeners.

Lettuce and herbs grow the best when the light is on all the time. Plants that have flowers or fruits should have a dark period of at least 6 hours.

The water pump is designed to be on continuously and it has low energy consumption. On the other hand, if you want to set the pump operation with a separate timer, you can also do that. The pump delivers oxygen to the water and provides oxygen and nutrients to the roots of the plant.

The power of the lamp is 24 watts and the pump power is 2,5 watts. If the device is on continuously (24/7), the monthly energy consumption is approximately 19 kWh i.e. 1,5-2,0 euros depending on your electricity agreement.

The lifetime of the lamp is approx. 2 years on continuous 24/7 use. are sold at retailers who are selling Herbie products.

First check the amount of water. If the pump gets in even a little air, the ‘recovery’ can take few minutes after you filled up with water.  If this does not help, adjust the pump to the full power for a couple of minutes (the adjustment lever of the pump to the left) and then back to the minimum. Check also that the pump is properly attached to the attachment pin. When changing the water, also rinse the pump with running water and see that there is no soil or plant remains in the holes. The pump grill should be removed by e.g. twisting lightly with your nails – this way the cleaning is much easier. – Place the pump in the same direction as the cord/water container. Press the growing medium by the pump in such way that the suction cups are attached to the bottom. This way the potential resonation decreases.
