Plantscape Designs Inc. has just been awarded a green plant service contract for a Woburn Rte 128 fitness center. Why, because tropical plants help clean the air in their facility, lowering the Co2 levels increasing the 02 levels within the fitness center. Green plants soften the hard glass and metal design of the fitness equipment and workout rooms. Finally, PDI green plants help soften the noise levels of the working machines the clients are using.
