Here we are a week and a few days later. One of the Forum Stompers didn't come up. It was probably my fault, I could have given them some more time in the DVD case before putting them in the cubes but I was excited! I germed another one and that one has popped up just fine.
Growth up top is pretty slow, and some of the plants seem a little droopy. Their roots just started to grow out of the net pots so maybe that has something to do with it? Or maybe because they are right at the end of the light cycle for the day?
I've got roots that I can see on 3/4. For at least one of the plants the rhizo-core net pots seem to be doing what it's supposed to. I've got a nice set of roots crawling their way towards the bucket right down the side of the inner cone. Going to switch the rez out Sunday and start them on some really low strength nutes.
I got the red frog air diffusers in the mail and went and bought a new air pump, these things are awesome. They make a ton of tiny bubbles to the point where it's almost a foam on top of the water. I'm hoping the roots love all the extra oxygen.
@CRiSPrGrow, I bought all the parts my self and set it up using an open source python script that a guy on reddit made. I've made a few changes and improvements. It uses an sht31-d temp and humidity sensor and wemo smart switches to control the fan heater and humidifier. It logs temperature humidity and vapor pressure deficit and turns the switches on and off to keep it within your set thredholds. All values are sent to a grafana dashboard that graphs the values and provides averages, etc. I haven't got around to it yet but I have an arduino and a ph probe that I want go use to send ph values to the grafana dash.
