Large Self Watering Plant Tray – 8L Capillary Irrigation System for Stress-Free Growing

The Large Self Watering Plant Tray is an autonomous irrigation tool designed to keep your crop hydrated with surgical precision, freeing you from the slavery of the watering can. This system uses gravity and capillarity to deliver the exact amount of water your plants need, ensuring vigorous growth and total peace of mind for you.

Are you tired of being tied to your grow room schedule?

We know the feeling: you want to go away for the weekend or just have a busy week at work, but the fear of your plants drying out keeps you stressed. Relying on manual watering means that one mistake or one forgotten day can ruin weeks of hard work.

If you miss a watering, the substrate dries out and the roots suffer irreversible stress; if you overwater to compensate, you risk root rot and fungi. It is a constant balancing act that consumes your time and energy, often leading to inconsistent results and mediocre harvests.

The Large Self Watering Plant Tray eliminates this problem completely. By providing a constant and regulated supply of water from the bottom, your plants drink at their own pace. It is the most reliable passive insurance for your garden, allowing you to recover your freedom while your plants thrive.

Key advantages over manual watering

Unlike complex drip irrigation systems that require pumps, timers, and electricity, this tray works with the laws of physics. It offers a silent and fail-safe operation that simplifies your setup significantly.

• Total Autonomy: The 8L tank allows you to leave your crop unattended for several days without risk of dehydration.
• Prevents Root Rot: By watering from the bottom, the substrate is never waterlogged, allowing for better oxygenation of the root zone.
• Nutrient Efficiency: Water does not run off through the bottom, meaning you don't wash away the cannabis fertilizers from the soil; everything is absorbed and used.
• Versatility: It is perfect for established plants but also incredibly gentle for delicate phases like cloning and early vegetation.

Real benefits you’re going to notice

The first thing you will notice is the freedom. Being able to leave your house for a weekend trip without asking a friend to water your plants is priceless. But beyond convenience, you will see an improvement in plant health. Plants love stability, and this tray provides a constant moisture level that manual watering rarely achieves.

Additionally, you will see explosive root growth. Because the water comes from below, the roots stretch downwards to drink, creating a robust and healthy root ball. This translates directly into stronger stems and, eventually, heavier flowers. It’s a professional technique made easy for any home grower.

How to use the automatic watering tray

1. Prepare the Tray: Place the tray on a level surface inside your grow space.
2. Install the Mat: Lay the capillary mat flat inside the tray. Ensure it is clean and free of debris.
3. Fill with Water: Pour up to 8 liters of water (or nutrient solution) into the tray.
4. Prepare your Pots: Make sure your pots have drainage holes at the bottom. This is crucial for the capillary action to work.
5. Place the Plants: Set your pots directly on top of the wet mat.
6. Initial Watering: Water the pots from the top just once to establish the capillary link between the soil and the mat.
7. Refill: Check the water level every few days and refill as needed.

Frequently Asked Questions

Can I use fertilizers in the tray?

Yes, you can add mineral nutrients to the water reservoir. However, if you use thick organic fertilizers, ensure they are well-dissolved to prevent clogging the mat fibers.

Is this tray suitable for clones?

Absolutely. It is excellent for cloning and young seedlings because it provides constant humidity without the force of a top-feed spray that can disturb delicate plants.

How often do I need to clean the mat?

It is recommended to wash the mat between grow cycles to remove salt buildup and algae. You can rinse it thoroughly with water and a mild hydrogen peroxide solution.

Does it require electricity?

No, this is a 100% passive system. It relies on capillary action, making it silent, energy-free, and immune to power outages.

Personal Experience of Pevgrow’s CEO (Alan)

I've used these trays specifically for maintaining my mother plants when I know I'm going to be busy with other projects or traveling. The peace of mind of knowing they have an 8-liter buffer is a game-changer. I noticed that the plants actually seem perkier compared to hand-watering because they never experience that "drought-flood" cycle. If you are a grower who values your time or just wants a safety net for your garden, this is one of the best low-tech investments you can make.
