I am here is California...and have had to change my power bill to TOU (Time of use) Run you grow at night and you get the best rate per KW....watch your base line...once over it your bill will be a killer...:wtf:

As far a easy to Grow and great medicine... Afgoo is very good and grows easy.... I would stick to indica type plants and that will keep the size down.
Purple kush, Black Berry Kush, Grand Daddy Purple, Green Crack ( make sure you are getting good genetics)

OG kush....all great for pain....if you need a day time medicine you can't grow wrong with NY diesel, or even sour Diesel..or Blue Dream..but you have to flower these early and they will get huge fast...lots of LST and cropping needed.

Do not try and grow all 12 of those plants first time out....I have found out when....you have problems....you have to be very proactive....few plants will equal success....which will keep you interested in growing....It is very easy to fail.

If your are still growing after the 1st year....people will know your medicine is good and they will be calling you.....

Good Luck
