CO2 enrichment

Hi,
My first grow is finishing nicely so I believe I got the basics right. I was thinking what to do next to get it even better. CO2 enrichment was mentioned lots of time as a way to significantly boost yield. I live in the city center and window in the grow room is open all the time. So my question is if any home-made (e.g. sugar/yeast) CO2 solution will make significant result or I should focus on something else.

I have a small grow 400MH/HPS, one big 50L pot with two LSTed flowers and all the basics are more or less in line (soil,PH, nutrients, temperature...)

The smell of fresh bread would drive me nuts. My friend uses bi-carb and vinegar on a slow drip.

I would say consider this

I will be using it in my next grow, I have read some favorable reviews by other growers using it

I have actually been wondering the same thing, has anyone really tested to see if the home c02 you mention actually works. Please post if you got experience with it.

20 pound CO2 tank, regulator should be way way way better than any yeast sugar water solution and over the long haul much cheaper and much easier to control and best of all no maggot gagging smell.

FWIW CO2 will NOT make a HUGE difference, it makes about a 10%-15% weight gain, but nothing magical like doubling your weight or anything.

What about an airsoft CO2 cartrege?

I have read that using club soda to foliar feed the plants will give them all the co2 that they need

Club soda is a bandaid really.

Love those sodium spotted leaves from the club soda!

The perfect amount of CO2 for 1 minute of growing!!! Might wanna pick up a few extra if you plan on growing longer.
