TNB Naturals The Enhancer, CO₂ Dispersal Canister-240g

I don't really know how much they produce however working 48 hours after placing this in my tent things started looking very noticeably better.

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!

This stuff is wonderful, it has you feeling so refreshed after a hot shower using it.

Nothing more than coarse ground sugar and a little bit of yeast sprinkled in. Ordered the dispenser about a month or so ago, it worked great! However the refill was a complete dud... Followed directions to the T and found virtually no increase in C02! I'm talking less than an extra 50 ppm... Totally not worth the money, when you could A) just buy the dispenser again for another $10 or B) choose another product entirely for around the same price.

I grow fire without and have used this but it needs refilling every week and a half $$$$ and you have to keep setting it off by shaking it up smh 🤦‍♂️ SO DONT waste your money or time btw insta Va_is_for_growers 🤙

Perfect little addition to a nice indoor 3x by3x6 tent

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

The bottle is nice and the cap helps let the right amount of co2. Now for the bad news, the ingredients suck. It's literally yeast and sugar with a couple pieces of aquarium gravel to help with aggitation when shaking. I made my own mix from 2 cups of table sugar and a single pack of instant yeast. My mix lasted 3 weeks and was still producing co2 when i replaced the mix. The included pack lasted a week and hardly ever put out any co2. I even used a 2nd separate run of tnb replacement pack in the bottle to the same affect. Save your money and just put a small hole in the lid of a 2 litre and add sugar and yeast. And if you want a real way to get co2 in your grow tent/room/closet get a co2 burner or get a refillable tank and a regulator. This is not the co2 solution you're looking for. You want to walk away in search of better options.
