Dear sri Praveenkumar sir, in mulching sheets,top silver and bottom black colour are good , to maintain soil wetness, humidity,to control Thrips and Mites, and to control weeds effectively. two varieties are available . one 30 microns and another 60 microns. 30 is good for short term crops like chrysanthemum, coriander,spinach like crops and 60 microns are good for crops like papaya,water melon, banana etc. I feel best are thaiwan company " Known You Seed Company" , and per acre Rs 5,000/- and 10,000/- approximate.  g.p.rao, farmer
