Just do one pot to see if you like it. 20 liter bucket, a net cup that fits some grow media and some air bubbles and a meter or two... boom done. Nute changes are super easy. You just buy a second bucket and swap it out. You gotta know where your Ph is at. It will usually go up a little everyday and you will want to keep it down between 5.5 and 6.5
Hydroponics Ph is usually around 6.3 on the upper end. The only other thing I can offer is that you shouldn't use organic nutrients. There are many organic nutes that work in water, but there are some that will have you growing frogs by the end of the week. You may know all this... just putting it out there
There's a bit to it, but I would say that the majority of things to learn is procedural.... when do you change nutrients, to SCRoG or not, nutrients that need to be added first thing before other nutrients after a nute change. Crap like that.
But here's the good news. You found some of the talented, and caring group online. With other forums you will see threads turn into lit fuses. People just want to start arguments. It's only a matter of time till one guy is impolitly told to perform very inappropriate sex with a close family member... not a good scene. Ask us, if you have questions. Cheers
