hello guys. i just bougth unis co2 controller like this http://www.ecotechnics.co.uk/unis.htm and have one simple question maybe you can help. i wrote to producers but nothing from them. in instruction i found that its very simple just set and forget as they say. just enter the volume of room ,one setting. But my question is, for example, if i have room with space of 10cubic meters and there are only 1 square meter planted,do i have to set 1 or 10 anyway. i will buy co2 sensor but later.will it be too much co2 if i set 10 ? i dont understand how this controller can work without sensor. its just not look precise to me now.
