Root Control Square Black/Gold Disc · Autopot AQUAvalve Protector · Prevents Root Blockages in 8.5L & 15L Pots

The Root Control Square Black/Gold Autopot is an essential protective disc designed to keep your plant's roots safely contained inside the pot, ensuring your automated watering system functions flawlessly without blockages.

If you are running an Autopot system, you already know how vigorously your plants can grow. But that explosive root development comes with a hidden risk: roots naturally seek out the water source, creeping out of the pot's drainage holes and heading straight for the AQUAvalve.

When those rogue roots reach the valve, it is a recipe for disaster. A blocked AQUAvalve means your system can either stop watering entirely, leaving your plants to dry out, or get stuck open, causing a massive flood in your grow tent. Constantly lifting heavy pots to trim runaway roots is a messy, time-consuming chore that ruins the automatic convenience you paid for.

The Root Control Square Black/Gold is the simple, logical upgrade to stop this nightmare before it starts. By placing this specially coated disc under your pot, you create an impenetrable barrier that repels roots, keeping them exactly where they belong while allowing water to flow freely.

Why this product improves what you already have

Without a root control disc, you are essentially playing Russian roulette with your hydroponic setup. You have to constantly monitor the trays, manually trim roots, and worry about potential floods every time you leave the grow room.

With the Root Control Square, your Autopot system becomes truly hands-off again. The special gold metallic coating naturally deters root growth, forcing the root mass to stay dense and healthy inside the pot rather than sprawling into the tray.

This means less maintenance, zero valve blockages, and total peace of mind. You can finally trust your automated irrigation to do its job, whether you are growing in a single pot or a massive commercial setup.

Key features you will notice from the very first grow

• Special gold coating: The metallic gold face actively repels roots, preventing them from escaping the pot and heading towards the water source.
• Perfect fit: Custom-designed for 8.5L and 15L square pots in the 1Pot and easy2grow systems, ensuring full coverage of the drainage area.
• Unrestricted water flow: While it stops roots dead in their tracks, the porous material allows water and nutrients to wick up into the substrate perfectly.
• Durable and reusable: Built to withstand constant moisture, it can be cleaned and reused for multiple growing cycles, though replacing it each run guarantees maximum efficiency.
• Zero chemical interference: Completely inert and safe, it will not alter your nutrient solution's pH or EC levels.

Who this product is especially interesting for

This accessory is an absolute must-have for anyone using bottom-fed automated watering systems who wants to avoid the headache of plumbing issues.

• Autopot users: Specifically those running 1Pot or easy2grow setups with 8.5L or 15L square pots.
• Growers who value peace of mind: If you leave your grow unattended for days, this disc ensures you will not come back to a flooded tent.
• High-yield cultivators: People growing vigorous, fast-rooting strains that tend to quickly outgrow their containers.

How to integrate it into your routine without overcomplicating things

Installation takes literally two seconds. Before you place your filled pot into the Autopot tray, simply drop the Root Control Square into the base of the tray.

Make sure the gold face is pointing UP towards the bottom of the pot. This is what repels the roots. Once it is in place, just set your pot on top and let the system do the rest. Check it between cycles, and if it is heavily worn, swap it out for a fresh one to keep your AQUAvalve safe.

Frequently Asked Questions

Which Autopot systems is this disc compatible with?

It is designed specifically for the square 8.5L and 15L pots used in the 1Pot system, easy2grow kits, and their extension trays.

Which way up should the Root Control Square be placed?

Always place the disc in the tray with the gold face pointing up towards the bottom of the pot. The gold coating is what deters the roots.

Can I reuse the Root Control Disc for multiple grows?

Yes, they are durable enough to be cleaned and reused. However, for absolute maximum protection against aggressive roots, many growers prefer to replace them at the start of each new cycle.

Will this restrict the water absorption of my plants?

Not at all. The material is highly porous, allowing the nutrient solution to wick up into the substrate effortlessly while keeping the roots contained.

Personal Experience of Pevgrow’s CEO (Alan)

Before I started using these gold discs, I had a couple of close calls with my Autopot setup. I was growing a particularly vigorous Sativa, and within weeks, the roots had formed a thick mat right over the AQUAvalve. I caught it just before it flooded the tent! Since I started dropping the Root Control Square Black/Gold into every tray, I haven't had a single blockage. I love the set it and forget it nature of bottom-feeding, and this little square is what actually makes that possible. I always recommend placing it gold-side up, and honestly, for the price, I just swap them out every harvest to be 100% safe. It is the cheapest insurance policy you can buy for your grow room.
