Autopot 8 Pot XL System – Hydroponic Kit with 100L FlexiTank

The Autopot 8 Pot XL System is the definitive tool for the grower who wants professional results with the simplicity of a passive mechanism. This complete kit allows you to grow 8 plants in 25-liter pots, fed automatically by gravity from a 100-liter FlexiTank, eliminating the need for pumps, timers, or electricity while maximizing root mass and final production.

Are you tired of hearing that hydroponics is "too complicated" or "risky" for the average home grower? There is a massive amount of noise online suggesting that if you don't have expensive chillers, loud air pumps, and digital timers, your plants will fail. This gatekeeping often scares people away from the most efficient way to grow.

This confusion leads to bad decisions: sticking to inefficient hand-watering that turns you into a slave to your garden, or buying cheap, noisy electric pumps that fail when you're on vacation. The result? Stressed plants, lower yields, and the constant anxiety that your crop might dry out while you're at work.

The Autopot 8 Pot XL System is the reality check the industry needs. It proves you don't need a degree in engineering to run a high-performance hydro setup. By utilizing the laws of physics (gravity) and the smart AQUAvalve5 technology, this system delivers a masterclass in efficiency, giving your plants a wet-dry cycle that mimics nature perfectly, without you lifting a finger.

Typical myths about passive hydroponics

• Myth: "If the roots sit in water, they will rot (root rot)."
  Reality: The AQUAvalve allows the tray to drain fully before refilling, creating a wet-dry cycle that oxygenates the roots naturally.
• Myth: "You need electricity and air stones for big yields."
  Reality: Oxygen is absorbed during the "dry" phase of the valve cycle. No electricity means zero noise and lower bills.
• Myth: "Hydroponic systems are hard to set up."
  Reality: This system connects with simple push-fit pipes. It’s easier to assemble than a piece of flat-pack furniture.
• Myth: "You can't use organic nutrients."
  Reality: While mineral nutrients are cleaner, you can use organics if you ensure they are liquid enough and you clean the lines occasionally.

What this product really does (and what it doesn’t)

The Autopot 8 Pot XL System is designed to provide a fully autonomous watering and feeding schedule. The core magic happens in the tray: the AQUAvalve5 opens to fill the tray to a specific level (20mm) and then stops completely. It will not open again until the plants have consumed every drop of that water. This ensures the roots are never "drowning" and always have access to oxygen.

Because this is the XL version, you are working with 25-liter pots. This allows for the development of a massive root ball, which directly translates to larger vegetative growth and heavier flowers. It connects to a 100L FlexiTank, which is collapsible and easy to store when not in use.

However, it is important to know what it doesn't do: it does not recirculate water (it's a run-to-waste system, but without the waste, as the plant drinks it all). Also, it doesn't force-feed the plants; it allows them to drink at their own pace. This means faster-growing phenotypes will drink more, and slower ones less, resulting in a perfectly tailored feeding schedule for each individual plant.

Advantages and benefits when used properly

• Total Silence: Since there are no pumps, you can place this in a bedroom or a stealth closet without any humming noise.
• Vacation Proof: With a 100L tank, you can leave your crop unattended for weeks (depending on the plant stage) without worrying.
• Massive Yields: The constant availability of water and nutrients, combined with the 25L pot volume, pushes plants to their genetic limit.
• Scalability: You can easily extend the system or arrange the pots to fit different Grow tents layouts.
• Efficiency: No water is wasted. Every drop in the tank ends up in the plant.

Tips to choose well according to your expectations

If you are looking for a system that allows you to control every second of the irrigation cycle via an app, this isn't for you. The Autopot is for the grower who values freedom and simplicity. It is ideal if you have ample space, as the 8 pots plus the tank require a decent footprint (ideally a 1.2m x 1.2m space or larger).

• Substrate is Key: You must use a 50/50 mix of absorbent substrate (soil or coco) and aeration (perlite or clay pebbles). Never use 100% soil, or it will become too dense and block the airflow.
• Nutrient Choice: For the smoothest experience, use high-quality mineral Hydroponic Nutrients that don't sediment easily.
• Tank Placement: The tank must be raised at least 15cm above the pots to ensure gravity does its job.

Frequently Asked Questions

Do I need to put an air stone in the FlexiTank?

It is not strictly necessary for the system to work, but adding a small circulation pump or air stone in the tank helps keep the nutrients mixed and prevents stagnation if the water sits for a long time.

Can I use clay pebbles at the bottom of the pots?

Yes, it is highly recommended to put a layer (2-3 cm) of washed clay pebbles at the bottom of each 25L pot to facilitate drainage and prevent the substrate from constantly touching the water in the tray.

What happens if the valve gets clogged?

The new AQUAvalve5 has a larger inlet (5mm) specifically designed to prevent clogging, even with some organic fertilizers. However, it is good practice to check the lines and valves between crops or once during a long cycle.

Is this system suitable for beginners?

Absolutely. In fact, it is often more successful for beginners than hand-watering because it eliminates the most common error: overwatering. Just set it up, fill the tank, and watch them grow.

Personal Experience of Pevgrow’s CEO (Alan)

"I've heard so many growers say they are scared to switch to hydro because they think they'll flood their house or kill their plants overnight. The Autopot 8 Pot XL is the system that usually proves them wrong. The first time I used the XL pots, I was genuinely surprised by the size of the stalks—gravity feeding seems gentle, but the plants respond aggressively because the water is always there when they want it."

"One thing I've learned: don't ignore the substrate mix rule. That 50% perlite/clay pebble ratio is non-negotiable if you want the system to fly. Also, the 100L FlexiTank is a lifesaver. I've gone on a 10-day trip and come back to a jungle that looked healthier than when I left. If you want to step up from soil pots but aren't ready for complex Hydroponic and Aeroponic Systems involving chillers and timers, this is your sweet spot."
