## Description

Product Description The smart co2 bag is very small and easily affordable bag producing carbon dioxide for your plants. It can multiply the growing speed of your plants and make fruits ripen faster improving taste, colour and crops. The smart co2 bag is safe to use, easy to setup without any maintenance required. It is the smallest and by far the most effective solution available on the market. Being like the oxygen to us humans, carbon dioxide is one of the most distinctive components of growing up plants. All plants need carbon dioxide to grow. If a plant cannot get enough carbon dioxide from the air, it will grow slower. The smart co2 bag is a powerful and easy way to add more carbon dioxide to your green room without overspending. Get a smart co2 bag 2-3 weeks after planting your seeds. Make 6 holes in top of the bag and hang it above your plants. In large green rooms, hang the bag over the aisles. The smart co2 bag only produces carbon dioxide in temperatures above 18 ºc (64 ºf). Store the closed bag in a dry and cool place under 18 ºc (64 ºf). When the smart co2 bag comes into contact with oxygen, it will start producing carbon dioxide. However it can take a few days before production starts. Depending on the air circulation in the green room, one smart co2 bag will produce enough carbon dioxide for an area of 10 m2 (170 ft2) for up to 3 months how to maximize the benefits? With the extra carbon dioxide, your plants can withstand temperatures that are 3-5 ºc (5-9 ºf) higher than usual. Compact size, maximum output.1350 - 1500 Ppm. (In 10m x 10m area) keep out of reach of children. Box Contains 1 x Smart Co2 Bag Hydroponics Grow Tent Room C02 Generator Like Exhale Grow Bloom

## Questions & Answers

**Q: I received mine today and they are all hard and Crystalle is that normal**
A: Na pal they should be like a fine powder inside and only go hard when they activate after you puncture the bags with a few holes so send it back and get a replacement sent back out 2 you.

**Q: How do you activate it? Just puncture the bag? Or inject some liquid/water?**
A: Put a few holes through the top. About the size of a pencil. You can add a few drops of water after a few days if it isn't working.

**Q: Is it ok to use this in small grow tent? Or is it overkill?**
A: I use it in a relatively small tent, 2m x 1.5 m and it just right.  Good stuff

**Q: How many do you get in a pack?**
A: @Shaun hit the nail on the head. But to truly know if it works, you will need to take a a co2 reading, then if it goes up, you'll know you have your tent sealed enough. Regardless it will give extra co2 to your environment, but depending on your environment, (how well your room is sealed) and you'll need a high ppfd of 1000+ for there to be good photosynthesis.
