- Comment on how do plants in a green house get enough co2? 2 weeks ago:
To add; I’d imagine decomposition of compost further contributes to CO2. The fact that CO2 is pumped in to some commercial greenhouses suggests CO2 is a limiting factor in plant growth, but I wonder whether hydroponic systems - lacking soil and hence decomposition - require more.
