so ok i am getting 2 t5 lights after that if i dont have the co2 diy they will still grow, Just not as fast?
Not quite. CO2 is required for the growth of plants, however, injection of co2 is not required.MDK500;1801213;1801213 said:You don't NEED it but, you will have better growth and health of the plants with it.
If you have fish/inverts producing some co2 in the tank it will do some, also if you have surface agitation and there are many animals/humans in the house, then your co2 levels will be higher. CO2 is needed, but you don't have to inject it unless you have a lot of lighting.crazyman229;1800823;1800823 said:so how inportant is the co2 do i NEED it or is it something i could do with out what would happen if i dont have it
