Even the AI version is priced reasonably enough not to break the bank. I like many of the features on the pro version, but not all of them. For example, I have the dongle to plug in my 630 watt nanolux LED fixture into the UIS system, but even though it turns the light on and off on queue, it leaves the green LED display on during the dark cycle ... I realize that many people buy into the notion that green isn't seen by the plants, but newer studies have shown that isn't completely the truth. Light is light and green light is still light. To me, the dark cycle should be 100% dark ... no glow from anything inside the tent. Aside from that, I have been pleased with the automation at an affordable price on the pro version.
@DaddyPrime2 - can you please share in a couple of paragraphs what pros and cons the AI version has compared to the Pro. Also, can you explain more about how AI goes about tuning in your grow parameters? I'm interested and would like to hear more from someone who isn't trying to sell me something.
