Some things I have learned the hard way some I read & some I grew up with but here's what i know. Dirt is easiest, even a doofus can grow something in dirt. Aero like Keef does is probably the fastest, and pretty forgiving for having pumps and such. 5 gal buckets DWC is the easiest water farming and flood and drain the most productive.
There is no substitute for lights when it comes to growing. My hps produce massive yields but lotsa heat. The leds are better at quality bud but don't produce as much quantity and are color specific. A flowering spectrum light and a vegging spectrum light are better (and more powerful) then one that does both.
Lastly, If you want quality bud, keep your flowering room below 80 degrees at the point under the lights. I can tell you this was the thig I addressed last and the thing that made the biggest difference in quality. I hope this helps you out. Just ask if you need anything else.:farm:
