Dosatron 4-Part Hobby Cultivator System (SYSD15RE05)

The Dosatron 4-Part Hobby Cultivator System (SYSD15RE05) is an automated nutrient delivery system designed to bring precise, repeatable feeding to hydroponics and indoor growing setups. Built specifically for small to medium grow rooms, this system allows growers to automatically mix and inject nutrients directly into irrigation lines or a batch tank, removing the guesswork and inconsistency that often leads to nutrient imbalances.

For growers running multiple nutrients in hydroponic systems, coco, or soil, maintaining consistent nutrient ratios can be difficult when mixing by hand. This system automates dosing using water pressure to power the injector mechanism, ensuring plants receive the same nutrient concentration every time. The result is improved nutrient uptake, stronger root development, healthier vegetative growth and more reliable flowering performance across your entire grow.

Designed for hobby cultivators typically running around 4–24 grow lights, the system can manage feeding for anything from a dozen plants to several hundred, making it a practical solution for scaling indoor growing operations without increasing labour.

Key Benefits

• Automates nutrient mixing for consistent feeding in hydroponics and indoor growing

• Maintains accurate nutrient ratios to support plant health and stable growth

• Helps prevent nutrient fluctuations that can reduce yield or cause deficiencies

• Ideal for grow tents, grow rooms and small commercial grow environments

• Compatible with coco, soil and hydroponic systems

• Flexible setup allows direct drip line feeding or batch tank mixing

• Repeatable dosing improves flowering performance and bud density

How to Use

1. Install the system inline with your irrigation water supply using the ¾ inch inlet and outlet connections.

2. Mount the unit securely using the supplied mounting bracket.

3. Place the suction hose with the weighted strainer into the nutrient solution reservoir.

4. Adjust the dosing ratio on each injector depending on the nutrient feeding schedule.

5. Start water flow through the system. The internal piston automatically draws nutrients and mixes them with the passing water.

6. Feed the solution directly to your drip irrigation system or into a batch tank for distribution.

Dosing Range: 0.5–5 ml per litre (1:2000 to 1:200 ratio).
If a nutrient requires higher dosing rates, multiple injectors can be used to achieve the required concentration.
