Straight Capillary Blanket 1200 X 45 mm – Passive Hydroponic Wick

The Straight Capillary Blanket 1200 X 45 mm is your best ally for maintaining a constant and autonomous humidity level in your crop, acting as a passive irrigation system that works 24 hours a day without electricity. This absorbent strip connects your water source directly to the substrate, ensuring that your plants drink exactly what they need through capillary action, eliminating the stress of manual watering.

Why do you need this capillary system?

Do you panic every time you have to leave your crop alone for a weekend? We know the feeling. You spend months caring for your genetics, and the thought of coming back to droopy leaves or dried-out rooting cubes keeps you from enjoying your free time. Hand-watering small pots or trays of cuttings every day is not only enslaving but also risky; one mistake in timing can ruin the progress of weeks.

Furthermore, inconsistent watering creates stress for the plant. Wet-dry cycles that are too aggressive can damage the root hairs, especially in young plants or clones that need stability. If you rely solely on your memory or free time to water, you are gambling with the health of your harvest. You end up either drowning them or letting them thirst, and neither option leads to the top-shelf buds you're looking for.

The Straight Capillary Blanket solves this immediately by automating the process naturally. By placing one end in a reservoir and the other under your pots or inside the substrate, the fabric "sucks" water up as the plant drinks. It creates a perfect balance: the plant only takes what it needs. It’s the most reliable, silent, and fail-safe method to keep your Cloning station or small pots thriving while you regain your freedom.

How to use the Capillary Blanket correctly

Using this system is incredibly simple, but doing it right ensures maximum efficiency. Here is how to set it up:

• Preparation: Soak the blanket in water (preferably with a pH of 6.0) before the first use to activate its absorption capacity.
• Placement: Place one end of the strip inside a water tank or reservoir.
• Connection: Extend the rest of the blanket along your Grow Trays or directly under the pots. Ensure there is good contact between the fabric and the drainage holes of the pot.
• Maintenance: Wash the blanket occasionally to prevent algae buildup or salt accumulation from fertilizers.

Advantages and benefits (FAB)

• High Absorbency Material: The synthetic fibers are designed to hold and transport water efficiently against gravity. Advantage: It ensures a steady flow without pumps. Benefit: You save money on electricity and equipment while sleeping soundly knowing your plants are drinking.
• Dimensions 1200 x 45 mm: A long, narrow strip design. Advantage: It fits perfectly in standard gutters, trays, or can be cut to size for individual pots. Benefit: Total versatility to adapt the system to your specific grow tent configuration.
• Self-Regulating Irrigation: Delivers water based on the dryness of the substrate. Advantage: Impossible to overwater as long as the setup is correct. Benefit: Healthier, whiter roots and faster growth rates for your cuttings and seedlings.
• Durability: Resistant to rot and fertilizers. Advantage: You can reuse it for multiple grow cycles. Benefit: A one-time small investment that pays off for years.

If you are looking for a more complex setup for larger plants, you might want to check our Drip irrigation systems, but for simplicity and efficiency with small containers, this blanket is unbeatable.

Frequently Asked Questions

Can I use fertilizers with the capillary blanket?

Yes, you can add nutrients to the water reservoir. However, we recommend using mineral fertilizers that don't clog the fibers easily. If you use organics, you'll just need to wash the blanket more often.

Is it suitable for large pots?

It works best for small to medium pots (up to 3-5 liters) or rockwool cubes. For very large pots (11L+), the capillary action might not be fast enough to keep up with a thirsty flowering plant, and you might need multiple strips per pot.

How often should I change it?

The material is durable. With proper cleaning between cycles (using H2O2 or enzymes), it can last for several harvests. Replace it when you notice it has lost its texture or ability to wick water effectively.

Personal Experience of Pevgrow’s CEO (Alan)

I honestly think this is one of the most underrated tools in the grower's arsenal. I use these strips specifically for my mother plants when I keep them in smaller pots to restrict their size, and for my propagation dome. Before using them, I lost a few batches of clones because I got busy and forgot to mist them or water the tray. Since I added the capillary blanket connecting the tray to a small reservoir, the humidity remains constant. It’s cheap, it doesn't break, and it saves you a lot of headaches. A "must-have" for the smart grower.
