Ive rocked many waterfarms outdoors. Dont run it as a full system, run them individually. The full system with control buckets and tubing is real close to impossible to run successfully outdoors in any kinda heat. The tubing will be gunked up first day it sits in the sun, and youd be draining and cleaning crud out of everything couple times a week. I Wrap the bottom with something lightproof first, seems simple but thats about all you need. Not sure where you live, but when its starts hitting 100+ where i am ill start putting plants around my waterfarm bucket to just block the direct sun from hitting it, give a little air gap between the direct sunlight and my insulated bucket, really seems to help from getting the bucket hot to the touch. I have tried a few types of media with em outdoors, fine coco is at the top. You will be surprised how often youll have to be filling the bottom, so having a substrate that will hold some moisture if you miss a day is the only thing thatll keep er going. Thats really it, no other mods or upgrades. You might want to add another bucket as a control bucket so you dont have to lift your plant out of its bucket to fill er up. But i dont even do that anymore, i just water right through the top of the plant, till it comes out the top of the drain tube. Here where i live ive gotta fill it up once a day every morning. DONT feed heavy, DONT, your plants will use up way more water then they do food, so keep your nutrients light and steady. Meaning pick a complete base nute (flora series is perfect), add cal/mag if ya need it and keep your ppms the same throughout flower. Dont raise your ppms or add bloomboosters, forgo that shit. Keep the same 600-800ppm range all the way through, and your golden. You start adding in extra goodies to help em out your gunna run into all kinds of problems. You can foliar feed them if need be, but even at 600ppm i never had a plant underfed. Waterfarms and sunlight=very feverish growth. Overall though its super easy and will blow your fucking mind with how fast and how large your plants will get. And keep in mind these are just the guidelines that i use, i hope that gives you somewhat of an idea of how someone who uses them outdoors uses them. Good luck.
