@@ -17,22 +17,22 @@ While maintaining the garden, I noticed small white flecks which I just assumed
The white flecks turned out to be eggs the aphids were laying. The sticky substance was honeydew, a sugary liquid that aphids secrete.

I bought a bottle of Safer's insecticidal soap to use against them. I have a walk-in shower in the downstairs basement bathroom beside the grow room, so I moved all the plants into there. I then sprayed the leaves as much as I could, top and bottom. I let it drain for a while and then rinsed thoroughly with water.

Three days later I noticed the aphids were still alive. So I bought five more bottles of aphid spray and emptied them into a bucket. I then took each plant out of the system and dunked them in the bucket, covering all leaves and the net cup. I pushed the plants in and out of the bucket forcefully, to make sure all the aphids were flushed off. I then rinsed the plants in the shower thoroughly like before.

Three days later I did this all over again, just to make sure they were gone. This seemed to work but I noticed the aphids returned a couple months later. It was one of the reasons I decided to end this round of growth experiment.
## Mould
A few weeks after the aphid dunking I noticed some kind of mould or powdery mildew on the strawberry crowns, right in the centre of the plants.

I assumed this was because I let the plants' leaves get too dense and they were blocking airflow to the crown. The airstone bubbles air into the water reservoir and the only place the humid air can escape is through the net cups and strawberry crown.
