For saving space and soil, this method also has several
other benefits, including no soil-borne diseases, no
weeds to pull and no soil to till, run-of-the-mill side
benefits of soil-less gardening.

Add Some CO2

Carbon dioxide (CO2) is essential for plant growth. In an enclosed growing area, as plants use up available CO2, their growth will slow down and may eventually stop. Replenishing CO2 will not only maintain growth but dramatically increase it.

Add Some CO2 To Your Hydroponic Gardening
By Shannon Burchill

We all have heard the perks of talking to your plants but never do anything about it. The one thing that most of us seem to forget about while indoor gardening is that plants love CO2. Many of you may want to add CO2 to your indoor gardening but find all the alternatives expensive and to bulky. I have found a little known trick that makes this easy for almost anyone to implement.
First you will take a large waterproof container and fill it part way up with water. Then you will add a couple cups of sugar to the water, followed by a package of baking yeast. Just give the concoction a good stir and set the container as close as possible to your hydroponic gardens, Done!

CO2 Release Systems

This setup will require the odd bit of work as it is a good idea to give the concoction a good stir now and then. About every couple weeks you may also have to add more sugar as it is used up by the yeast that creates the CO2.

I have noticed that some of my hydroponic gardens react well to the little bit of added CO2 where as I cannot tell a noticeable difference with others. You may also find that certain plants will react more favourable than others. This setup is very simple and affordable and well worth experimenting with.
