Could plants be grown at Mars equator in greenhouses?
i read your other post to this question and NASA already has plans to introduce earth plants to mars if indigenous life exists. first they plan to warm the planet by releasing some of our lovely greenhouse gasses (there is your greenhouse) and then introduce simple single celled plants that can survive on a pure CO2 environment (most earth plants still need oxygen) once they have created an oxygen environment then we are well away towards colonisation.
