If you are going to be in-n-out with an inconsistent schedule, your chances of success diminish to nil. Growing cannabis is a hands-on obsession. (hobby)

Depending on someone else to properly care for your plants doesn't usually work so well. Rarely do they have the skills nor incentive to pull it off.

If after your trip you plan on being around for a few months straight, I'd recommend you start a shopping list for nutrients and equipment, and keep your eyes open for quality cannabis genetics. Bagseed often comes with someone else's headaches bred into 'em. For instance, commercial growers are usually less inclined to cull an unseen hermaphrodite, which weakens genetics over time (successive generations) and creates substandard bagseed. Regular bagseed is usually a good way for you to form the basics. But just like a potential girlfriend, bagseed often come with 'baggage' and can be a handful.

Perhaps start reading some grow logs just to get yourself familiar with the terminology, growing processes, basic growing skills. Studying the indoor growing forum, basic gardening forum and FAQ's till your eyes bleed couldn't hurt, either. :thumbsup:

If signing-up for college, how about a couple of horticulture or plant biology courses...?
