Terra Aquatica TrikoLogic, Trichoderma for roots

Terra Aquatica TrikoLogic contains Trichoderma harzianum for the root zone. See how to use it in soil, coco, and hydroponic systems.

breaks down organic matter
protects against the development of pathogenic fungi
stimulates plant growth

Trichoderma lives in soil, coco, or similar substrates, breaking down organic matter and releasing minerals. This process of decomposition and nutrient release is essential for organic growing, organic hydroponics, bioponics, and aquaponics. As it grows and forms colonies, Trichoderma also releases a range of compounds that stimulate plant growth and substances that inhibit or kill soil pathogens that could otherwise harm your plants, as recent studies have shown.

How to use:

As with all aerobic microorganisms, the better the oxygen supply and the more stable the pH, temperature, and humidity, the healthier and more effective Trikologic will be.

For seed soaking or as an additive to water/nutrient solution for seedlings/cuttings and young or mature plants: Add 1 g per 15 to 20 liters of water or nutrient solution every 6 to 8 weeks.

For mature plants in soil or coco: Add 10 g per 150 to 200 liters of water or nutrient solution every 6 to 8 weeks; simply add it to the irrigation system or directly onto the substrate.

In hydroponics, where the roots are fully submerged in water, and in bioponics: When plants are young and have small root systems, Trikologic needs a base for colonization and reproduction. To provide this, use a commercially available biofilter, or hang a 3 to 5 L plastic basket filled with 80% clay pebbles and 20% coco substrate under the falling water in your reservoir, e.g. at the return point in our Growstream® systems.

Use with:

all GHE nutrients from GHE - mineral or organic
in any substrate, hydroponics, or outdoor growing

VENTS Boost series turbine fans:

Application. Designed for supply or exhaust ventilation systems requiring powerful airflow: commercial, office, and other public or industrial premises, as well as rooms with high humidity.
Design. The housing is made of polymer. Thanks to the conical polymer impeller with specially profiled blades, the circumferential velocity of the airflow increases, resulting in higher airflow and pressure compared with the performance of standard axial fans. The specially designed diffuser, impeller, and airflow straightener at the fan outlet ensure smooth airflow distribution and enable the best combination of high airflow, increased pressure, and low noise. The fan housing is equipped with a sealed terminal box for connection to the mains.
Motor. VENTS Boost fans are equipped with single-phase, high-efficiency, three-speed asynchronous motors with low power consumption. The motor is equipped with thermal switches for overheat protection. Ball bearings ensure a long service life (approximately 40,000 hours of continuous operation). The motor's ingress protection rating is IPX4.
Speed control. The fan has no speed switch; the desired speed is set manually when the power cable is first connected.
Installation. The fans can be installed anywhere and at any angle in the duct system. Several fans can be installed in one system in parallel to achieve higher airflow or in series to increase the operating pressure in the system. The fan housing is equipped with mounting brackets for the floor, wall, or ceiling.

Air Flow

Up to 3580 m³/h at 50 Hz

This makes the OVK 4E 400 suitable for applications where a large volume of air is required at relatively low static pressure. This is where the axial fan performs best – for free discharge through a wall, large openings, or short, low-resistance air ducts.

🔊 Noise

Sound pressure level: 53 dBA at 3 m

This is a high-flow industrial fan, so it is not designed for applications where low noise is the primary priority. For installation in sensitive environments, suitable sound insulation or distancing from the working area may be provided.

VENTS P3-1-300 speed switch – 230 V

€13,50

VENTS P3-1-300 is a series of wall-mounted switches for controlling multi-speed fans with a 230 V single-phase power supply. The series mainly includes the P3-1-300 for three-speed fans. Control is step-based – the user selects one of the pre-set motor speeds rather than adjusting the speed smoothly.

P3-1-300 is not a smooth speed controller. It is designed specifically for fans that come from the factory with three separate motor speeds. Through the rotary switch, the user selects low or high speed or turns the fan off completely.

This makes it suitable for a number of two-speed VENTS fans, including models from the TT series, where the manufacturer lists it as an external accessory for controlling the two-speed motor.

Manufacturer's manual "P3-1-300" user's manual 08-2019 (V23EN-02)

Operating mode

Control is as simple as possible:

OFF – fan is off

- low speed
- medium speed
- high speed

P3-1-300 switches between the pre-set speed leads of the motor. Therefore, it must be used only with a fan whose motor is designed for three-speed operation.

Compatibility

P3-1-300 is designed for three-speed fans.

It is important that the specific fan has separate electrical leads for low, medium, and high speed. If the motor is single-speed and allows adjustment by changing the voltage, another type of controller is required, for example from the RS-1 series.

Installation and protection

P3-1-300 is designed for indoor wall mounting in a suitable mounting box. The manufacturer expressly warns against:

direct water spraying;
rain;
direct sunlight;
installation directly next to heating appliances and other heat sources. Electrical connection must be carried out with the power supply switched off and by a qualified person.
