So I'm new to all this lol go easy on me. I've got 16 plants (12 female 4 male) growing inside until they're strong enough of outdoor weather. My idea is to use a rain barrel with a garden hose spigot on it and use a drip irrigation system to water them. My question is basically how to go about what size emitter and how many gph per hour for how many hours and if I should get a timer? I just need help figuring out the semantics. Thanks
