VEVOR CO2 Burner, 8 Brass Burner CO2 Generator for Plant, Liquid Propane LP Carbon Dioxide Generator, 22352 BTU/Hr, Built-In Electronic Ignition, for Greenhouse Green Tent Hydroponic Room Grow Room

Use this for a month already have no problems with it. And the price of it is just amazing compared to some of the branded ones that is double the price or even triple, I found no problem using this and is very easy to setup and the good quality no leak or any so far so good. Great product great price.

very easy to install and setup. please, please, please don't forget to pair it with a controller. you're risking serious injury and potentially death if you don't control the output of this unit. not to mention any potential harm to the plants. i use an autopilot controller but any competent one will do.as for co2 in general. my experience is that it's a great magnifier. if you're garden is rocking righteous vpd, than co2 will amplify that goodness and will put your very healthy plants in to overdrive. if your garden is unhealthy (in that i mean environment not conducive to maximum transpiration), than co2 will amplify that too and will stress the hell out of your ladies. herms will follow and you'll have a fully seeded garden.

Works. The regulator is 3/8'' pipe thread. Came with plugs that will allow you to reduce the number of burners from 4 to 3 or 2 for less BTU/Co2 output

I purchased two of these units for my garden, both work as advertised. However one of them arrived with a faulty AC adapter. Reached out to customer service multiple times. There was a language barrier to be sure, but I was finally able to relay my problem effectively through a few photos and a short video. Agent i was exchanging emails with asked for shipping info and said they'd send a new AC adapter. Two months later and still nothing. TLDR: bought 2 units, 1 came with broken parts, customer service fell short.
