Need some advise
I am looking for successful greenhouses owners. I have built 2 in my back yard and the plants I grow there are doing ok. What I want to know if about regulating CO2 into the greenhouses. I have heard that if I get some tanks of CO2 and get the right level in the greenhouses the plants will produce even better. I would like to find someone that is using the process to get an opinion and ask some questions on the right level of CO2 to use. I am pretty new to greenhouse use and want to make the most of them. If you can help let me know.
