Sounds good, VV. Whatever you can do to automatically manage conditions will make things happen more reliably. I've gotten by for many years without a thermostat in the clonebox, but as you might expect, air temps were all over the shop dependent upon the ambient air temp around the clonebox. When ambient was around 23-25C, the lights warmed the interior of the box to an ideal 26.5-27C with the fan constantly running. When ambient was really low, I managed temp by running the fan on a timer, 15 mins on, 15 mins off. Worked sorta OK, but I expect the clonebox to be much more consistent now with the tstat installed. Moreover, minding the clones is easier when the temps are stable. An unexpectedly warm day might cause the cubes to dry out more quickly than usual, leaving me with wilted or cooked clones when I water at the usual time of day.

You'll like the improvement in reliability of a flood system- they simply can not clog from nute salts as there's no small sprayer or dripper apertures. Much less maintenance.
