When the cops knock on your door! First off DO NOT PANIC! 
If they have a warrant, let them in and keep your mouth SHUT!

If they do not have a warrant!  Do not let them in!!  
They will try to convince you that it will go better for you if you just let them in!!!

 BULLSHIT!!!

Make them go get a warrant!!!!

It will take them at least 24 hours before they will be able to get back!! they might threaten to arrest your wife! or call Children & Family's on your kids!! It is all BULLSHIT!!! They are just trying to make their job easier! its a pain in the butt to get a search warrant & put a raid together! DO NOT GIVE THEM PERMISSION TO SEARCH YOUR HOUSE! if they search your house with out the warrant anything they find will be thrown out in court!! as soon as they leave!! immediately shut down your grow room!!! 

DESTROY ALL POT PLANTS!!!  hide the grow equipment at another location! REMOVE ALL SIGNS THAT THERE WAS A GROW ROOM!! within 90 minutes of them leaving there should be NO SIGN THAT YOU HAD A GROW ROOM!!!

About your electric bills. Most electric company's put right on the bill the NEXT METER READING DATE! It is VERY important that on meter reading day, THAT YOUR METER IS NOT SPINNING AT MOCK SPEED!!!  If you are running 2-4000 watts of lights, You MUST CUT BACK YOUR LIGHTS THAT DAY! Cut it back to just one light!   Meter readers are trained to look for meters spinning faster then normal, Using just one light will keep your light cycle going, So it won't effect your grow cycle, & It doesn't raise any eyebrows with your meter reader!

  WASHINGTON (AP) -- Police violate the Constitution if they use a heat-sensing device to peer inside a home without a search warrant, the Supreme Court ruled Monday. This is a "Major" victory for the medical marijuana grower!! If they can not just use it with out a warrant, The next place they will start looking is your trash! To get the evidence they need for a search warrant! But as a reminder the cops do not need a warrant to search through your trash! So you need to be real sure that you do not throw anything connected with pot in your trash cans!! Everything trash from your grow room MUST be destroyed! Prior to throwing it in the trash! 

 Side note! I have yet to find any trash from a grow room that could not be destroyed or melted down by throwing it into a Charcoal Grill .
