Best Twin Wall Polycarbonate Greenhouses 2017

While most hobby greenhouses on the market us less expensive thinner walls and roofing materials (the crystal clear walls are as thin as .2mm), the Monticello uses professional grade 8mm twin wall polycarbonate. This is the same thickness as used in the commercial greenhouses. The twin wall polycarbonate acts as a double pain window keeping cooler air in during warm months and insulating the greenhouse from cold air in the wintertime. This not only makes the Monticello more efficient to grow in for a longer period of time than other greenhouses but it also adds to the efficiency of growing, cutting down electric bills for those who choose to grow year round.
