Defo worth it mate....
I live in east sussex and has really good luck a few years ago with a outdoor crops,got about 3oz a plant and didn't use anything just sunlight. Went to check on them once every two weeks so didn't take up any time. Just remember to raise them up indoors an use a mold resistance strain that doesn't require alot of up keep..
Good luck and would love to see a pick after your first grow
