CO2 Tablets come as a tub of 60 and are a great, low cost way of increasing carbon dioxide levels. The slow release tablets dissolve in water, gradually releasing this useful gas into the growing area. They are easy to use too! Simply place one or two CO2 Tablets into a cup of water and place the cup among the plants. Over the course of a couple of hours, the tablets will fizz away and give off CO2. Each glass/ tablet combo will treat about a metre square or so, but it isn’t an exact science! More tablets will of course further increase levels, but beyond about 2000 ppm, there will be little benefit.
Adding CO2 is one of the best ways you can increase the performance of your plants. The plants use it in the chlorophyll to make sugars which then go on to fuel growth of all kinds. In a grow room, carbon dioxide levels can dip, especially if the ventilation system isn’t up to par. This can seriously stunt the plants as they will have much less raw materials to build from. Add some CO2 Tablets to get the very best out of your plants!
What can I use alongside CO2 Tablets for best results?
It would be advisable to turn off fans while using CO2 generating products. This would avoid it all being lost into a filter before use. If this is not an option, we would suggest placing the CO2 source low in the room so the gas pulls up through the leaves. Although CO2 is heavier than air, the air circulation system keeps the flow moving upward, and the CO2 would go with it. We also recommend using Advanced Nutrients Nirvana when adding carbon dioxide. This increases the plants ability to absorb CO2, improving the overall effect.
At Straight Up Hydroponics, we have a couple of other options for carbon dioxide generation. You can see these products on our website by clicking here.
