Must need for personal indoor growing
For the value for money this is easily an essential item for indoor/grow rent growers. Easy and simple for anyone who hasn’t used a product like this before in their growing, no leaks if following the instructions, and plant growth is very noticeable from a before using - after using this product. I subscribed right away to get this item once a month. From an experienced master grower; it’s essential for indoor and grow tent growers on any experience level.

Good
Helped with plant growth, a small amount of spillage & hangs VERY GOOD!! I would recommend this for certain plants but not for all plants depending upon what they need. I found a tea light candle can do the same when lite for a few minutes & blown out. That trick is great for when you just have an odd plant or 2. This bag is good for when you have 3+ plants or a plant is growing very large!

Killed plants
My daughter did a science fair experiment on extra CO2 and plant growth. This product killed the plant within hours. First she did it with lettuce, then with radish sprouts. Both times the control thrived while the experiment plant died immediately. I emailed the company but haven’t heard back. Edit: I did get a reply to my email and they did refund my order. So customer service is good. But I would still be hesitate if you want plant growth to use these bags.

It's supposed to have liquid guys chill...
Towards about half way through the bags life cycle it will start to have liquid build up. It's normal and c02 does not smell very good don't breath it in doofus. This product works as advertised. More light will get 10% increase in biomass but adding c02 sch as this will add up to 50% if not more biomass! I'm a new grower and on my 2nd run adding this increased yields substantially. Very obvious and noticeable difference if all other environmental factors are taken care of.

I feel like I'm professional now! So ez
Sorta, lol. Did it make me a scientist?? In a way, but also...not at all. Don't have to be! Very cool, simple and easy to use. Works for a small area and no special equipment or worry. Poke it and hang it. It ABSOLUTELY added in better trichome production for me. My light is heavier on blue than red, so it was noticeable.

Absolutely amazing product
The media could not be loaded. This Co2 bag by far works better than any similar product. After 10 days in a 5x5 my plants jumped 3in and actually saw results after 24hrs. Saw some reviews and product instructions say not to hang over your plants or lights because they drip as of today I have not witnessed any dripping with 8 tiny razorblade holes. I move a lot of air so maybe the bag isn't respiring as others have written but very happy with the product overall.
