Excellent value for money. My co2 meter is picking consistent levels above 1200 ppm. Will be buying again. Shame there isn't a bigger version!

The item did not come with the zip ties it says are included

Followed all instructions, temperature is about 23°C depending on light cycle, purely because I do not want to stress my plants. It does drop depending on house temp but only overnight. Humidity is over 50%RH most of the time.I stabbed the bag at the top in 6 positions as instructed. It's hanging above the plants as instructed.It's been hanging a week no measurable difference in CO2 levels. Added 1-2ml of water to the bag again as instructed... a slight hardening of the powder has occured but again, no measurable increase in CO2.Because of the measurables and the environment I grow my plants in, I will not be purchasing this again. In my experience, it has had no measurable impact to the CO2 levels in my growspace.

Fantastic product for the price which surprisingly works. My plants react noticeably well to this, your environment needs to be right though so if you follow VPD and ensure your temps and humidity are correct this product will work wonders.
