I feel like a large part of it has to do with equipment.
Would you have been able to do it without a rotovap?

Yes absolutely, ethanol evaporates quickly on its own. I use a reflux condenser while doing reflux so that I am not unnecessarily putting the fumes into the carbon filters on fume hood. Also I can reuse the ethanol when I rotovap it. You don’t even have to concentrate down if using poor solvent(like water) just have to time the cooling and supersat different than with out evaporation. Just have to play with timing.

what about the controlled cooling?
Is there any equipment that you'd recommend?

You can just use your hot plate. Make a sand box for better control. If you don't have presets, just kill the heat plate and insulate everything. Doesn’t have to be fancy, can even use towels to insulate. Can just bump plate on if cooling is too quick. I use my plates thermistor and presets to control, but most plates will hold heat well if you just insulate. Just keep separate thermometer in with the solvent as it cools so you can monitor.
