What duck was talking about is enhanced CO2. For this you need controllers, monitors, enhanced lumens (more light), an airtight space, coordinated exhaust, etc, etc. CO2 enhancement needs to be monitored and controlled, so using things like those buckets, bags, dry ice, vinegar and baking soda, etc, etc is really a waste of time energy, and money as there is no way to regulate it.



there's roughly 300-400ppm of C02 depending on location around the world. thats why we use such big fans. not only do they keep our grow rooms cool, they exchange the air in the grow room every minute or 2, so that the ppm's remain in the 300-400 range. when people use tanks or generators, the ppms are jacked way up to 1500ppm. the controllers are there so that the ppm stays that high at all times when lights are on.

My advice is dont over think it, that can lead to "loving them to death".

I always tell new growers to keep it simple, use a 1 part nute like Floranova Grow for vegging and advance from there.

There are alot of things that are not 100% necessary to have a very sucessful
harvest.

I really like the GH Flora Nova grow. It is a 1 part nutrient that works really well. I prefer it to the 3 part for vegging. However I had problems with the bloom and use the Flor series (micro and bloom only) for flowering.

I've been using home made yeast and sugar co2 generators for about a month now.The difference to me is noticeable..would be nice if someone could do a co2 vs non c02 grow.The fertilizers I use on the nitrogen side come with added carbon to them also..another option to consider when adding that good co2 to the mix.

I was researching water cooled because of the heat issues I have read about with the non-water cooled generators.

Just sitting here bonging and thinking
You are quite correct AFA the on demand water heaters do the same thing at a much lower cost than the horticultural units. Design wise, they are pretty much identical (the water cooled units).

Sorta like a bag of Magnesium Sulfate being 3x the cost of the same size bag of Epsom Salts even though the ingredients are identical.

any help on brand names, or another name for, stand alone water cooled ac units?

The day I started using co2 is the day I learnt what the plants truly need and love. Worth every $ spent on average I veg clones no more then 18 days 1500ppm all day cycle and I stop 5th-6th week flower depending on strain.

Here I was thinking the more time I spend in the rooms the better.
I've been meaning to put a comfy chair in there for naps. And I often turn the exhaust off when I'm in there.
With this hobby growing, it seems less I try, the better.
Ramp, schmamp.

I myself have a high tech CO2 generator !-- Grow room temp is also the right temp to ferment !--

@keef for CO2 in a greenhouse, one can use compost under the flooring, for CO2 and heat.

Duck I grow in a spare bedroom that's open to room air with a concrete floor -- I enjoy brewing and the grow room temp seems to work well for it !-- I seriously doubt my brewing raises the CO2 level much but more is more !-- Brewing and Growing weed just go together well for me !-- They both need to be hidden so being in the same place seems logical !-- Maybe one day I have a sealed grow room and I can raise the CO2 concentration !-- Without a sealed grow U just can't control CO2 levels but weed grow just fine on room air !-- I grow aero and ideally I need a higher O2 level for my roots and higher CO2 for my leaves !
I ain't figured that one out yet !

I got plans for a small mom and pop commercial grow soon as the law changes some !-- That CO2 from brewing might not help my plants that much while they growing but it will help later !-- 5 gallons of Apple Wine and I freeze 4 gallons of water ice off of it -- When my time comes to move some weed -- U might need to sample some Jack before we start talking price ? -- I get my price maybe I throw in a couple bottles or a case of Apple Jack depending on how much U want !-- So in the end the CO2 gonna help me just fine !
