Co2 tips hints and info


Recommended Posts

Hi All,


I have been readying up on Co2 systems, I have read a lot of good stuff about it. However cant really find much on the bad about it. Apart from the cost of buying the bottels, and the set up cost. I have one for grow in my room untill I move to a fully sealed ( aka insalated shipping containter). So the use of Co2 is looking like a must, just to keep the work of cutting heaps of holes in my new room down and also water tight. So I ask, has any one used them or are using them, does the cost weigh up. I have read with the right temp and hum in your room you can get 2 - 3 times more yeild, which would help with the cost of runing the room and the Co2. Also I like the fact that your need to run your room at a bit of a higher temp. Which means less power spent on cooling. Any first hand info would be great.


P.S: Any places that people buy or hire the Co2 from would be good. I have a mate that is a plumber that can get me one bottle here and there but not on a regular base.


Thanks all

Depending on the size of your room, If if you go to a homebrew shop you can 'buy' a 2.3kg, 4.5kg or 2.3kg bottle. I have a 2.3kg bottle I use for homebrewing which cost by memory $180 then when its empty you can take it back and get a new bottle for $20.


EDIT: sorry they come in 6.4kg, 4.5kg and 2.3kg.

Will you be running an A/C unit?

From what I've read a split level inverter would be the way to go as it blows the same air into the room that it sucks out maintain the Co2 levels and pressure. I'm no expert, but I would think you'd need at least a 6.3Kw unit. Would also help with the humidity down.


Cheapest units I've found:



Also which brand are you considering? from what I have read, sentinel and harvest master seem to be the best brands.
