TNB NaturalsThe Enhancer, CO₂ Dispersal Canister-240g

First time using this product. Have heard of for years. Always tops in non cannister CO2! Well, we finally tried it out for just 4wks during flower between 3.5 weeks in(after stretch period), until 7.5 weeks during the major growth period in flower. Just as a test.. Definitely a very noticeable difference! I screwed up though after buying the bottle and refill together. I didn't secure the bottle right. TIE BELOW THE CAP, UNDER THREADING, LIKE SOMEONE POSTED A PIC OF HERE IN REVIEWS! Great folks to buy from, as they were understanding and actually gave me a discount when buying the refill! Growers who really want to help others! Not a seller with all kinds of different types of products, etc, but specializing in growing products only. Very impressed, and we only used for 4 wks! We've purchased a Hydrofarm CO2 Monitor, but shipping problems resulted in showing up around the 12th day of 14 day period. I was still getting around 800PPM, so they do last almost 2wks. Next time I'll update this with real numbers when at it's best! I'm pretty sure levels were over 1000PPM for most of the 2 week period of expiration, but will update you! Great results from what I noticed. DEFINITELY A DIFFERENCE MAKER! AND FROM OTHERS WHO GROW! WE REALLY NOTICED QUITE A SIZE DIFFERENCE! BEST WAY TO TRY? FROM THESE GUYS. BEST DEAL AROUND!

love this stuff

Upon adding to the environment plant growth exploded.

I’m rewriting my early review of this product. Previously I had used this without any CO2 monitors and after purchasing a monitor I found that the CO2 in my 12’x8.5’x8’ greenhouse was only at 500ppm-600ppm. They claim that I should be getting at least 1000ppm. I purchased another monitor and it read within a few ppm of the other monitor. I mixed up a new bottle per instructions and gave it a few days and had the same results. I decided to go with a CO2 tank with a controller and monitor but just installed the controller at first to get a reading which just like the other two was reading 500ppm-600ppm. I now am hooked up with a CO2 tank & controller and have it at 1000ppm and am finally getting the results I should have been getting from the TNB naturals. IMO I wouldn’t waste any money on these as they don’t perform anywhere near what they advertise. If you purchase these I would suggest getting a monitor to see what your CO2 levels are so you don’t continue to waste your money on a product that just doesn’t work. I’d prefer to use an organic product but this one just doesn’t produce the CO2 they say it will. ( I did shake the bottle every day and the hole was not plugged in the lid)

So i took down my scrog net this morning and defoliated a bit then the mail came with this co2 bottle and idk if it was removing the netting but she perked up big time and looks so much happier than she did this morning first pic of from 11:21am 2nd pic is from 3:05pm today, will have to do an update but if its made a difference in a few hours then i would say its very effective but lets check back in 10 days and see

This is my 3rd bottle of this stuff and I only use it for the first month of seedling/veg stage for my plants. During veg(day 14-40) I will add the bottle which is very easy to setup. Just add warm water and shake. The bottle lasts about 2-3 weeks and really makes my plants explode during early stages of life

Meh. Testing showed very little increase in co2 in a 4x5 tent recorded using an ink bird meter. Maybe touched 550ppm on a good day.
