After a while of detailed instruction-giving, Harold finally began planting the different plants according to the directions Althea gave.
Althea asked him to do two approaches: One was with a nursery, while the other was to directly plant the seeds on the system soil. In fact, the past few days (other than doing a few hours of training every day), Althea had already began with her nursery, but it was focused on a couple of local plants, and she decided it was time to try more varieties.
Althea assisted with this task, where he only had to gather soil in a specific spot in the system farm and place them on makeshift containers carved out from soft porous rocks (which would temporarily be their pots until they found a better alternative).
The boss did the rest of the planting and recording.
