After the first week of daily plant inspection, our AstroPlant seemed to be doing well, and we concluded that we could probably trust it to survive if we glanced away for a moment. The basil was left to fend for itself on day 8; nobody came into the lab to check on it.
On day 9, we found the plant had indeed survived its time alone, but it looked slightly shrunken and, once again, there were black spots on some of the leaves.
We removed the worst of the leaves and changed the water. Having given the plant a week without nutrient solution, we also introduced a new solution: Canna Aqua Vega A & B. We added 30ml in total – 15ml of A, 15ml of B – to the ten-litre water supply.
Our next visit was on day 12. This meant the plant had been alone for two days in a row, which we were a bit nervous about, given that it hadn’t been looking its best after a single day without a visit. However, it seemed to have taken well to the nutrients, and we were pleased to find it looking better, with fewer spots on the leaves.
