The Associate Diploma has two parts to it:

These eight modules form the Advanced Certificate in Horticulture. If you simply complete these eight modules and go no further you may attain an Advanced Certificate. Each module takes approximately 100 hours to complete, so the estimated duration for the eight modules is 800 hrs (minimum).

All of these are available online, or by distance education. Once again, each module takes approximately 100 hours to complete, so the estimated total duration of the seven modules is 700 hours (minimum).
