Yes.
I see that your grow is in a garage that's "not ideal". Looks like we're members of the same club! My 2' x 4' tent is in an unfinished garage in SoCal. I phrase "controlling the grow environment' as "influencing the grow environment" and it takes some work to deal with each of them.
Re. RH - the eternal struggle. A spike in humidity is damaging if you end up with mildew or some other malady. Other than that, I can't think of an serious issue. Having out of control makes it hard to manage vapor pressure deficit, a measurement that is very important in all horticulture. I learned a lot from
this site and, a couple of years later, it's the best summary info I've found on the topic.
The the Inkbird and the AC Infinity Controller 69 -
@Cannaficionado brings up some good points and, as of a few days ago, my Inkbird devices are on their way to the Minors. I've been using their RH controllers, a temperature controller, as well a PulseOne ($200) since I started growing again 23 months ago and, I can no longer make a compelling argument to buy or use those devices.
If a grower needs to control only one device, the Inkbird is $50± and will do the trick. The Controller 69 allows you to control 4 devices so, even though it's $99 (for the "Pro" model which support WiFi), there's tremendous value because it's "smart". The Inkird, my RH controller was named "Wetbird", is a dumb device in that it maintains a constant setting, within the parameters that you set. In contrast, I set my Controller 69 to keep VPD at 0.9, plugged Hugh (my humidifier) into an adapter and, as of two days ago, all I've had to do it watch the Controller do its thing. That setup would have saved me dozens of (billable) hours over the last two years that I spent adjusting RH values that are needed to keep VPD in range.
