Hydro is an easy way to get alot of weight very fast once you get a system down. If you get good, you'll have more weed than you can reasonably smoke between harvests if you intend to go perpetual. This can be very good or a pain in the ass, that's your call.
Don't get in over your head. You just need a system, light, timer, medium, compatible nutrient line, and something to measure ph and ec. The nutrient line never needs more than 3 parts, some are one part. Don't fall for the nutrient scam, weed can grow damn near anywhere, it doesn't need 10 different boosters and flower accelerators.
Whatever system you choose, pay attention to how the roots are getting what they need. The fittings should not be leaking. Roots should not see the light. The roots shouldn't be sitting in a stagnant pool, nor should they be dry. They need plenty of air, and enough water/solution. Over feeding is always worse than over feeding, and they are picky, but it takes alot of negligence to completely fall short of the finish line.
I recommend hth pool shock for sterility in the res.
