Okay Hydrophiliacs, after a couple of successful soil grows – first with Jack's Classic, then with organics only – I find myself wanting to give hydro a try. I'm a dedicated, frugal DIYer, so buying a pre-fab setup is not part of the equation. I'm looking for advice on putting together a 3-4 plant system that's simple, productive and resilient, and will all sit on a 45” x 17.5” platform under my 48” x 22” scrog screen. When I first started thinking about hydro, my vision was of the standard 4 x 4-gal bucket system with 3 for grow and 1 as the reservoir. So, without thinking through the implications and options, I picked up my buckets, $50 worth of 1.5” PVC pipe, joints, and bulkheads (crap, those things are expensive!), and started cutting holes and assembling. But after getting 50% completed, I'm thinking this bucket setup will end up being a huge pain in the arse going forward, and it doesn't seem make a lot of sense. A lot of complexity for what is, in the end, a large shared tank, so, why not just build my own tank? Seems like it would greatly simplify assembly, cleaning, maintenance, recirculation & mixing, everything. Before I go any further down this path, I'd appreciate your experiential input. If you're using buckets, are they as big a pain as I perceive, or is there some advantage that I don't? Do you wish you could start over with 1 large tank? I've NEVER been exposed to hydro before, so after I get my general design settled, I'll be back with a bunch of newbie questions. Please bear with me and share your experience. If you're a DIYer, what do you wish you'd done differently?
