Multi Duct MD200 Hydroponic System – Complete Kit for Massive Yields

The Multi Duct Hydroponic System MD200 Complete Kit is the ultimate weapon for growers who want to stop playing around and start producing seriously. This automated system allows you to grow multiple plants with minimal effort, ensuring explosive root development and harvests that will leave you open-mouthed thanks to its constant nutrient flow technology.

Why switch to the Multi Duct MD200?

Are you tired of hauling heavy bags of soil, dealing with the mess of runoff water, and spending hours hand-watering every single day? Managing a medium-to-large indoor crop with traditional pots can become a slavery that consumes your free time and breaks your back.

If you stick to the old methods, you are not only working harder but also limiting the potential of your genetics. Soil creates resistance for roots, and manual watering often leads to imbalances—either drowning the plants or letting them go thirsty. This results in slower growth, smaller buds, and a lot of wasted potential.

The Multi Duct MD200 is the logical solution to end these hassles. By switching to this system, you automate the feeding process, eliminate the need for heavy substrates, and give your plants exactly what they need 24/7. It is the smartest way to work less and harvest more.

Maximum oxygenation for beastly roots

The magic of this system lies in its design. The plants sit in channels where the nutrient solution flows constantly. This mimics the benefits of the best Hydroponic and Aeroponic Systems, ensuring that the roots have unlimited access to oxygen and food simultaneously.

In a day-to-day context, this means you will see vegetative growth rates that are impossible to achieve in soil. The roots grow long, white, and healthy, forming a dense mat that absorbs everything. For you, this translates into shorter crop cycles and significantly heavier flowers.

How to use the Multi Duct MD200 Complete Kit

Setting up this system is easier than it looks. It is designed to be assembled quickly so you can start growing immediately.

1. Assembly: Assemble the support stand and place the channels (ducts) on top, ensuring they have the correct slope towards the reservoir.
2. Connection: Connect the water pump in the reservoir and the delivery pipes to the top of each channel.
3. Substrate: This system is perfect for using Rock Wool Substrate blocks or slabs. Place your rooted clones or seedlings in the blocks directly onto the channels.
4. Nutrients: Fill the tank with water and add your fertilizers. Adjust the pH and EC to the optimal levels for the phase your plants are in.
5. Operation: Turn on the pump. The water will flow up, run down the channel bathing the roots, and return to the tank to be recirculated.
6. Monitoring: You only need to check the tank level and parameters periodically.

Key advantages and benefits

• Large capacity reservoir: It holds a large volume of water, which gives you autonomy, meaning you can go away for a weekend without worrying about your plants dying of thirst.
• Low profile design: The system is low to the ground, which maximizes vertical space, allowing your plants to grow taller before reaching the lights.
• Recirculating system: It reuses water and nutrients, which saves you money on fertilizers and is more environmentally friendly.
• Unlimited oxygenation: The constant flow prevents root rot and accelerates metabolism, resulting in harvests up to 3x larger than in soil.
• Cleanliness: No soil means no mud and fewer pests, which simplifies maintenance and keeps your grow room pristine.

Maintenance and care

To keep your MD200 running like a Ferrari, hygiene is key. Since the water recirculates, it is vital to keep the tank clean. We recommend changing the nutrient solution completely every 7-10 days to prevent nutrient imbalances. It is also essential to use a Humidity controller and temperature meters for the water; if the solution gets too hot, oxygen levels drop.

Between crops, run the system with water and a little hydrogen peroxide or a specific cleaner to remove salts and pathogens from the ducts and the pump. This ensures your next cycle starts problem-free.

Frequently Asked Questions

How many plants can I put in the MD200?

It depends on the size of the plants you want to grow. If you do a Sea of Green (SOG) with small plants, you can fit quite a few. If you let them grow large, you will need to space them out more to prevent them from fighting for light.

What happens if the power goes out?

Since the roots are in rockwool blocks and the channels usually retain a little humidity, the plants can survive a short outage. However, in hydroponics, it is always good to have a backup or check the system daily.

Is the pump very noisy?

No, the included water pumps are designed to be submersible and are generally very quiet. You will hear more of the trickling water (which is relaxing) than the motor itself.

Personal Experience of Pevgrow’s CEO (Alan)

I've tried all kinds of hydro systems, and the Multi Duct style is a classic for a reason: it just works. What I love about the MD200 is the height. Many systems are too bulky and steal a lot of vertical space, but this one stays low, which is great if you're working in a tent or a room with a standard ceiling.

My pro tip: Don't skimp on the initial root washing of your cuttings before putting them in. Make sure they are healthy and white. Once they hit that flow in the channel, the explosion is insane. I've pulled some of my heaviest harvests with this type of setup because the plants just eat and eat without stopping.
