Increases light intensity and light hours increasing photosynthesis
trapping heat energy
increased temperature and therefore increased photosynthesis
pumping CO2
increased co2 concentration increases photosynthesis
why do greenhouses have limitations
due to the fact that the conditions do not reflect those that occur in the natural environment and only plants that grow in small places can be measured
FACE- free air co2 environment
pumping co2 at larger trees in natural conditions to investigate plant growth liked to changing atmospheric co2 concentration
