Co2

I wanted to help my little seedlings along so i decided on making my own homemade co2. JUst some simple warm sugar water mixed with yeast. I have 3 different bottles with this mixture. Each bottle has a small hole in the top to release the CO2. This is all inside my greenhouse(my greenhouse is rather small). Will this help the plants or not do much? I also shake the bottles every hour to mix up the mixture and release more co2. Thanks

If they are seedlings then just talking to them gives them all the Co2 that they need. As a brewer, of course I have tried the method you described. Wasn't worth the effort.

I guess my question should be is this even the slightest bit beneficial to the plants at this stage of growth?

Maybe in a sealed environment where there is little to know Co2 present. If you have decent airflow in your green house then you probably already have all the co2 that your plants need.

Depending on the size of the seedlings, you are probably just wasting your time and money. Plants take in CO2 through their Stomata on the underside of their leaves. Since your plants are seedlings, I am going to guess there isn't a lot of leafs yet, at least not enough to warrant using extra CO2.

I would wait until they have at least a few nodes, and 10+ leaves or so.

Also, how can you be sure how fast your bottles are producing CO2? With holes on the top of the bottles, it is impossible to see how much CO2 your little yeast guys are producing. Instead you should have a 1/4" airline put into the hole on the top of the bottle, with the other end of the line attached to a very small air stone. Take this air stone, and put into another bottle with just plain water in it, then you will be able to see the CO2 bubbling up from air stone in the plain water.

Or you could go to a Home Brew store and buy one of these for a dollar. If it bubbles, co2 is being produced.

Or you could put a little yeast in sugar water and if the fucking sun comes up again like it did today it will produce CO2. It ain't frickin rocket science and I know a dollar ain't a lot of money but what you get for $1.00 is a bubble show. WHOOOOOfuckingHOOOOOO!

Just do it!! Can't hurt, might not help but if want to jack off a jug of sugar water on the Hour. Go for it dude!!

That was a helpfull comment... <end sarcasm>

Actually in addition to knowing that your bottles are actually producing CO2, using the system I mentioned, or the product BendBrewer mentioned you are also able to tell when your yeast isn't producing anymore CO2 and you will know it's time to freshen up your bottle. Depending on the ratio of sugar to water, your CO2 producing machine will have varying lengths of life.

I have used similar systems for fish tanks that have live plants in them, and there were many times where I got the mixture wrong and it didn't produce enough CO2, and other times where it almost produced too much. If it wasn't for the tubing going into the water I would have no way to gauge how much CO2 was being produced, and when it was finished.
