CO2 Boost for Indoor Grow Tent - Ready to Use - Natural Carbon Dioxide CO2 Boost for Indoor Grow Rooms - One XL CO2 Bucket Covers up to an 4'x4’ Area - Pro CO2 XL Bucket

Works great but, the value for the money just isn't there. I can make 10x as much CO2 using Yeast and Sugar. I thought I would try it any way once and see if it was worth it. It worked but, if you have a little ingenuity and time you can make a far better faster producing and longer lasting contraption.

*UPDATE* My c02 meter was malfunctioning! Great product! I got this five days ago and so far almost no change in C02 saturation. I find that hard to believe. Either my bucket is defective, my C02 meter is broken, this bucket takes a while to produce or it’s just plain ol garbage. I haven’t spoken with the manufacturer yet. After I do, and figure out what’s going on I may update this review.

Unlike the hanging bags I’ve found tear easily if not real careful this is a bucket. It’s tiny But seems to work great except for the blacking on the filter. I haven’t had mold or issues from it though. Thanks

Product only lasted 1 month before the filter at the top turned black/brown around 3 of the holes and started emitting a strange smell. For the amount of $ I spent on this. I’ll never buy it again. It seemed to have no effect on my plants after that. Instead, I replaced this with two Exhale CO2 bags and my plants couldn’t be happier. I really wish this product worked better, but it seems their quality control sucks. I wasn’t going to leave a review for this, because I figured maybe I just had bad luck, but after remembering how much I paid for this I was pissed! Go get urself an Exhale bag, just remember it takes about a month to produce the full amount of CO2!

These buckets are by far the best thing you can get bang for your buck. The CO2 bags are junk and the reason that is because the bucket has air that forces the CO2 out of the bucket and over your plants. Most of the time it's out of stock so if it's in stock get a bucket and try it out make sure it comes with the air pump included not the refill.

10x16 shed. 6 plants. Great light. New Bucket caused 3 plants under bucket to turn from deep green to yellowish green in 2 days. So the bucket is doing something. Rearranged plants just now, stayed in shed prob 15 minutes, then stopped and admired my work , while I was standing directly under the bucket. Bad idea, but a good test. I started getting pinpricks in scalp and hands. Looked up noticed I was under the bucket. Vacated shed immediately. ((Shed door had been closed whole time)). I’m Knew at this whole co2 thing ,,,,but folks, the darn thing is doing something. Vent your area while inside. It was my mistake. I’ll buy it again Next time for sure.

I don’t know that I seen a noticeable difference

First indoor cannabis grow in a 6 x 3 area with more than enough light to benefit from added CO2. Before putting this in the room, my plants were thriving. After...they continued to thrive. Since it's my first indoor, I can't compare what effect it may have had, although it certainly didn't hurt. Unfortunately, I was unable to measure the ppms. BUT - a quick google search showed that sugar, water, baking soda and yeast can also create CO2 for much less. Only downside is that it's advised to change every 10 days or so. Happy gardening.
