I don't think there is any strict PAR requirement for plants; I would say as long as you have medium light and above (say 50 micromoles per square inch of PAR), with good fertilization and CO2, HC should grow fine.

Regarding your second question, I would say at medium or perhaps medium-high, CO2 becomes a much better option than Excel (economically and also for practical reasons).
