I'm a new grower. This helped me streamline my grow. The controller combined with the ionboard s22 and the s4 fan is wonderful. I've been able to schedule my light on and off, change fan speeds based on temperature or humidity thresholds. Supposedly there's a grow cycle setting but I haven't found it yet. It's great however I have no baseline to compare it to. It does what I want and for me that's all I care about.
