Aeroponic cloners like 75 degrees for new roots. This is pretty easy to control with a digitally controlled seedling mat under the cloner.

You\'re reservoir temps for growing should be in the 60-68 degree range. Once you have a high humidity environment (in the root zone) and start getting above 68, you have the perfect conditions for phythium (root root) to grow and take out your garden..
