I echo what Hick said. If you get busted for an indoor op (don't say it can't happen), your parents will suffer the consequences and you and your bro could end up in foster homes.
Grow outside this spring. You live in one of the premier area's in the U.S. for growing pot.
Plus you'll end up with WAY more weed (see pic).
Between now and the spring, read everything you can on growing. Get some hiking gea (boots/backpacks), and a trail guide. Get some seeds. Save $ for potting soil. When weather permits, hit the trail and find yourself a nice REMOTE location, near (but not next to) a water source.
And adhere to the #1 most important rule of growing pot: TELL NO ONE.
I hear what you're saying Bea.
And I will certainly abide by any decision Marpas makes concerning underage posters.
-99.9% of people who want to learn to grow have already smoked marijuana.
-Most likely they are already involved in the "black market" in buying it.
-There are a lot worse things that a couple of teenagers with spare time on their hands can do besides backpacking and stopping off on the way to water some plants.
-I gave the advice I did as an alternative to growing at home most likely without their parents permission.
I'm not telling anyone anything they couldn't read thermselves, without joining or posting.
