Compare
When you compare traditional controlled growing environments with our Tropos system, there is virtually no comparison. Most conventional systems require significant ongoing investments in electricity, natural gas, CO2 and water while producing lackluster results in terms of plant growth and quality. The quick-glance comparison chart below tells the story.
