Few bucks? Try couple thousand. If I pull the trigger, I am for sure running those heat exchangers. So it would go, filter>fan>hood>exchanger. Think it would vastly cut down on AC. I also saw sealed off duct flanges on both walls, dual fans on both ends going thru lights when on.
There are so many methods you can use to create Co2. Ranging from 20$ to 200$ to 2000$
Buying a CO2 generator is a extremely expensive, and can be a waste of money. Same-goes for home-made methods as well, ...CAN BE a waste of money. However, ..For those who can't spend thousands of dollars, and those who can like to get into arguments about which is better ...I think I'll stick to explaining how to make Cheaper home-made designs, so more people and everyone can get use out of them. Both work. Both fail. Both have different costs.
I can get a 5* months supply of constant CO2 for 200$ or
less. Look into a product called
Co2 BOOST or Co2 Pucks. I use one of these methods + 2 home-made methods that can cost as little as 20 dollars a Month. Sometimes less
2 different kinds of home-made Co2 Generators/Dispensers... 20$-30$ is a good price for both of them.
I buy in half bulk. Enough for at least one month supply at a time...it's not hard to figure out.
1 - Either empty 2L pop bottles, or one big 5 gallon water jug, or pail, bucket, etc.
Aquarium tubing from the pet store (3-8$)
Sugar
Yeast (Dry Brewer's Yeast)
2 - Couple Big boxes of baking soda
1-2 Big jugs of Vinegar
FIJI water bottle (I find rectangular shape works easier sometimes)
I use pin needles
Container
NOTE: I'm explaining how to do all this with minimum $$$.
The first method is making alcohol. The yeast eats the sugar and produces Co2 and Alcohol. The ratio of sugar to yeast is always a lot higher. The more sugar and yeast, and BIGGER chamber, ..the more/longer Co2 will be produced. You make a small hole in any of the lids, maybe 2 or 3 if you have a pail and those giant round lids, and you insert the aquarium tubing, and seal it off... I use crazy glue. A lot of people already know this method, it's common, cheap, simple, and no matter what it does create extra Co2 which is a beneficial aspect.
Some people find doing this a waste of time, but that's up for debate, as some people love creating things like this for fun and experience, - You start off making pop bottle Co2 dispensers, then get creative and start coming up with your own ideas, like i thought up my drip system for Co2, A 2 big boxes of baking soda and big jug Vinegar (less than 10$) ...can produce Co2 in a drip system steady for weeks if made properly. There's also some other things you can do to this method.
I have done it. And it does work, as the meter tells all.
The second method is making your own drip system. Basically get a container and pour a nice amount of baking soda. You then fill the FIJI water bottle with vinegar and either put 1 really really tiny hole, or ..(it should be experimented with but maybe more, it's always different every time i make one). Vinegar is thin. I usually put one small hole in the lid VIA fire and needle, tac...and leave the need in the hole (melted pastic or C.glue) suspend the FIJI bottle over the BSoda container, and make sure it drips vinegar onto the Bsoda, ...10 or less drips a minute is good.
Voila co2 making drip system for 20$ or less.
I always make a set up of each method in a grow room, along with Co2 pucks, or, sometimes Co2 Boost. Some people say none of these methods work, but I've used them all many times, and I also use Co2 meters so I can VISUALLY see how much ppm of Co2 my chamber has. They all work. You just have to learn how to handle a gaseous nutrient.
Another good way for Co2 ...is going to Wal-mart (only some Wal-marts have it) ...Is purchasing DRY ICE
There are many other cheap ways as well.
Supplementing Co2 is a great way for speedy growth (faster cell division). Before carbon can be incorporated into plant tissue it has to be “reduced” from its state in the CO2 molecule; it has to be chemically reacted with water and high energy electrons to become a “carbohydrate. The more light the more Co2, faster growth takes place.
Six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar and six molecules of oxygen. It is easy to see that environment conditions and the amount of light available dictate the level of sugar that the plant will produce. This energy is used by the plant to maintain biological function; any excesses in production will be stored in the plant.
Carbon Fixation is carried out by the enzymes RUBISCO and sometimes PEPCase.
TRIACONTANOL nearly doubles a plant’s rate of photosynthesis! Research suggests this is because TRIA directly increases the activity of enzymes involved in photosynthesis and growth, such as RUBISCO, PEPCase, ATPase, NADH-oxidase, and malate dehydrogenase. When using products that contain any of those enzymes, or Triacontanol the fatty acid and My personal favourite phytohormone, alone with Brassinolide., you should also be increasing your Co2 production
