If you are going to buy any books, music, videos, etc. from
Amazon.com,
please come to this page first, then click on the link, or do a
search from this site.
That way the site makes a little money to stay online, your price will
not go up.
Don't use one of those adapters that converts a
3 prong to a 2 prong unless you know for certain that
the socket has been properly grounded.
You can
install a new breaker in the service panel and run 3
wire Romax to your grow. Then you can install a 3 prong
outlet (preferably a GFCI). Buy a basic wiring book and
follow the instructions exactly. Electricians don't
charge much compared to morticians, so don't be afraid
to hire a pro.
Add a 20 amp, not a 15 amp. The cost is the same and
the 20 amp is no more hassle than the 15 amp. While
you're at it, consider installing 2 runs of wire so if
your grow ever needs another breaker, the wire will
already be in place.
