Hey there, don't take advice from someone who has never run an aero system. They are usually intimidated by areo, often a soil grower, and will resent you suceeding with areo. It's a simple system and a great one. I have used aero systems extensivly over the last ten years and would not go any other way.
The biggest thing people will try to scare you about will be a nozzle clogging or power failure yadayadayada. Pure drivel. A clogged sprayer is one of many. Sprayers aren't supposed to be aimed directly at the roots anyway so there will still be sufficient mist from the other sprayers. What happens if the power goes out with a flood system and rockwool? Exactly, the rockwool drys up and plants die. With Aero same thing except the bottom half of the roots are in WATER, therefore no death.
Get yourself a system and experiment. How else will we progress? Listening to someone say "oh I wouldn't do that" even though it's because they are afraid of failure and afraid you will suceed. Lame. That's why we love hydro right? If something goes wrong it takes a couple days to fix. Big deal. Trail and error are a way of life, you will greatly benefit from an Areo system, and that's gonna be your best yeild!! Good Luck!!
Sorry Stinky, can't sit by and watch someone stifle someone else looking to advance knowledge.
Yes I have 15 years horticulture experience AND work at a Hydro shop and my customer's love me and come back for solid advice to make educated decisions before they buy.
