OneHit has a spinning disc type mister out of some model of humidifier. Have been looking for a cheap source for years. Remember seeing , first hand, some on handheld booms used with backpacks for application of something on tobacco crops back in 80's. Very fine micronised mist. Dewey misters seem like a nice simple option.
Have you looked at mapito or Fytocell type media (aminoplast). Think commercial players go few cycles before discarding in big f/d setups.
Go for single channel relays and good brands. That way if you do have a failure it is easy to swap one out.
I think house of hydro are reasonably priced for what you get.
Don’t want to have to deal with disposing of anything. It’s a bloody nightmare disposing of the stems as it is.
Can get rid of bodies too. Remind me not to cross you. Have you looked at using a spreader mat for the roots instead of hydroton?
My attraction for the spinning disc atomiser was the durability and simplicity. No need for pumps of nozzles. Unclogging etc. Again, for cloning, dewey misters seem like a reliable option with minimal moving parts.
I have everything running through relays, lights, pumps, fans etc. Raspberry pi as the controller. Mycodo as the software. Might use home assistant next time as it seems to habe a big user base and wont disappear one day
Something for the roots to hold onto? You could flood and drain with no media whatsoever. But plants need supporting.
spreader mats only coat the bottom of the flood table though? What goods that do when the water spreads on it’s own anyway?
Just searched those misters up. Hadn’t heard of them. I don’t really like the idea of multiple air line hoses all over the place.
Oh they’d be supported by a neoprene ring within a piece of polycarbonate roofing stuck to an inch of XPS foam to keep my res coolSomething for the roots to hold onto? You could flood and drain with no media whatsoever. But plants need supporting.
I wasn’t sure it was possible to find co2 sensors etc for ardunios/ raspberry pie. But if you can it’s definitely something I’ll be doing
Seen a few with affordable variants around. MH-Z xx something. Best to check library availabilty and connectivity (uart/spi/i2c) depending on how you want to run them (arduino or other).
