are you just sticking the bud in the microwave by itself? i know when cooking it the conventional way you need to cook the weed in a fatty food (butter is most commonly used) maybe try using a decent ammount of bud and butter in a bowl...microwave it for a minute or two (DONT LET IT BURN) AFTER IT MELTS and try eating a butter sandwhich...i know it don't sound too good but it's the only way i can think of while still using the microwave....and i wouldn't use full power since you wouldn't use full power to simmer something in the microwave (i am a pretty decent cook) i'd say around 50-60% power...remember don't start counting the two minutes until the butter has completely melted....afters it's all done strain the weed out as best as you can, and either stick it in the freezer or fridge (freezer might not make it go back to the correct form but it will be faster, you mentioned your parent's aren't gone for long).......but i have never done this so i can't be sure if all this will work...but theoretically it will work....but you try it at your own risk...well for good meausre you might not want to strain out the weed and while the butter is melting make sure to stir it every 10 or 15 seconds....becasue this whole theory goes out the door if the bud isn't actually submerged in the butter.....good luck....
