A: Track your order and if you don't get anywhere, I would cancel the order and find a different person who has a better % Feedback and the sales.

**Q: Is o e bag enough for 4x4 tent?**
A: Co2 is meant to be used within a closed environment. Using co2 In a tent with constant air exchange when co2 is needed the most is rather pointless. I've used these bags the past 4 years no benefit and didn't work as co2 is intended to work. Co2 is used during photosynthesis when plants are in flower, normally that's when light will be 100% and the plants will be consuming and using the most co2. Really no need for co2 in vegging and seedling stage. Plants cant take enough light to matter
