CO2 Kit Disposable Bottle 1Kg – Complete System with Solenoid Valve

The CO2 Kit with Disposable 1Kg Cylinder is the definitive tool to unlock the biological potential of your crop, transforming a standard harvest into a professional one. This complete system is designed to inject the exact amount of carbon dioxide your plants need to accelerate photosynthesis, resulting in explosive growth and significantly heavier flowers.

Why are your plants asking for this CO2 Kit?

You have the best LED lights, premium nutrients, and a controlled climate, but you feel like you've hit a "glass ceiling" in terms of production. You see the plants healthy, but the buds aren't swelling as much as they should, or growth slows down when the temperature rises slightly. Does this sound familiar?

The problem is often invisible: CO2 depletion. In an enclosed grow tent, plants consume the available carbon dioxide in minutes. Once levels drop below 300 ppm, photosynthesis stalls. It doesn't matter how much light or food you give them; if they can't breathe, they can't build mass. You are literally starving your plants of their main building block, wasting electricity and time.

The solution is to enrich the air, and this kit is the easiest way to do it. By maintaining levels between 1000 and 1500 ppm, you turn your grow room into a high-performance engine. The CO2 Kit with Disposable 1Kg Cylinder ensures that your plants never stop processing energy, allowing them to withstand more heat and produce denser, stickier, and heavier buds.

How this kit improves your current setup

If you are relying solely on air extraction to renew CO2, you are limited to ambient levels (about 400 ppm). By introducing this kit into your Climate Control strategy, you are tripling that availability. The difference is noticeable in the plant's structure: thicker stems capable of supporting heavier colas.

Unlike homemade yeast and sugar experiments that produce unstable gas and bad smells, this kit offers surgical precision. Thanks to the included solenoid valve (electro-valve), you can connect the system to a timer so it only doses gas when the lights are on, which is when plants actually use it. No waste, no hassle.

Key features you’ll notice from the very first grow

• Complete Automation Ready: Includes a high-quality solenoid valve that opens and closes the flow electrically. Connect it to a timer and forget about manual dosing.
• Precision Regulator: The pressure reducer allows you to fine-tune the amount of gas released, ensuring you don't empty the bottle in a day.
• Compact & Efficient: The 1Kg disposable bottle is perfect for small to medium tents (up to 1m²) where space is gold.
• Heat Resistance: Plants enriched with CO2 can thrive in temperatures up to 30°C, making this kit a lifesaver for summer grows.
• Plug & Play Replacement: Once the bottle is empty, you simply unscrew it and attach a new disposable cylinder without changing the regulator setup.

Who is this product especially interesting for?

This kit is a game-changer for specific grower profiles:

• The Yield Chaser: If your main goal is to beat your gram-per-watt record, CO2 is the missing variable in your equation.
• The Summer Grower: If you struggle with high temperatures, CO2 allows plants to close their stomata less often, reducing water loss and stress.
• The Micro-Grower: Ideal for cabinets or small tents where a large industrial tank would be impossible to fit.

How to integrate it into your routine without overcomplicating things

Setting it up is easier than it looks. You simply screw the regulator onto the bottle and connect the solenoid valve to a standard timer (the same type you use for your lights). Program the timer to turn on 15 minutes after your lights go on and turn off 15 minutes before they go out.

To ensure the gas reaches the plants, place the outlet tube at the top of your grow tent (CO2 is heavier than air and will fall onto the plants). It is highly recommended to use measuring instruments to monitor ppm levels and ensure you are in the sweet spot of 1000-1500 ppm.

Frequently Asked Questions

Is it difficult to assemble the electrical part?

Not at all. The solenoid valve usually comes with terminals where you connect a standard power cable. You just need to wire the phase, neutral, and ground (if applicable) to a plug, and then plug that into your timer.

How long does the 1Kg bottle last?

It depends on the flow rate and the size of your extractor fan, but in a 1m² tent dosing during light hours, it can last between 2 to 4 weeks. It's always good to have a spare.

Can I use this during the flowering stage only?

Yes, and in fact, that's when it's most effective. While it helps in veg, the massive weight gain happens if you use it from the second week of flowering until the flush.

Is it safe to use indoors?

Yes, completely safe for plants and humans at the recommended levels (1000-1500 ppm). Just ensure your room is not hermetically sealed for days; normal ventilation cycles are enough.

Personal Experience of Pevgrow’s CEO (Alan)

I remember the first time I decided to make the jump to CO2. I had been growing for years, tweaking fertilizers and buying expensive lights, but my yields had plateaued. I thought CO2 was only for huge commercial warehouses. I was wrong.

When I installed a kit like this in my personal tent, the change was radical. The plants literally looked like they were on steroids—greener, standing upright praying to the light, and the heat that usually stressed them in July didn't bother them at all. If you want to see what your genetics are truly capable of, you have to try this. It's the difference between a good harvest and a legendary one.
