You'll need a power inverter, used commonly for camping.
nope im thinking off growing lots of stuff as a hobby not pot, it would be good to have somewhere where i can grow my plants all year round a I don't have the climate. A place to put sickly plants or ones ive had for years that might not make it through the winter because of the low light levels.
inverter is basically soundless some have a cooling fan they come in different ratings make sure its large enough to handle your requirements
Why? Are you trying to grow pot and stay off the power grid?
search "12v growlight" on ebay for ideas.
how can i run a 20w growlight from a battery, it usually just plugs into the wall but im looking for other ways to run it I cant use a generator because its to loud
