Wow! It's working great.
Received the and put in my 4x2x6 tent with 2 plants. It took 24 hours to start generating CO2 but it's got the tent environment at 600+ and climbing. So far it's doing what they said it would. I'll repost in a couple of weeks. So far so good.

Lasted 2 weeks killed all plants
Somehow after I started using this my plants developed some sort of fungi and this only lasted 2 weeks before it dated eating the plastic and leaking into my dwc res. It completely Rubin’s my entire grow and I had do a whole investigation and cleaning process multiple times before I realized that the C02 was leaking and killing my plants also what fungi is used to print his c02 or is it a chemical because I’m sure this fungi has gotten onto all my plants

I added this to my grow tent and to be honest I'm not 100% sure it helped but I can say they're bigger now so maybe 😂

May be worth it... may not be
One of those things I will most likely buy for a simple fact my indoor plants need more CO2... however price is up there, and bag quality isnt great. I had a leak on the bottom exactly 1 month after hanging it inside my tent. Good thing it wasnt directly over the plants itself and mlre in the corner. So quality isnt all there. I dont have ways to measure CO2 level, but I have noticed a difference in my yield after using this as well.. HOWEVER I cant say its because of this product alone. I have changed alot of things in my grow so it can be many factors, like better light, better feeding methods and schedule, better nutes, better soil trace minerals bio char, azomite etc etc. Im sure CO2 played its small role in it as well. So after all the investment goin on, whats another 20$ if theres a chance it will increase yield and be worth the extra nug? I just wish was made better, n leak proof if im paying 20$. 13 would be great 15 reasonable. 20 is up there

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.
