Monthly Update 28/06/2020.
I am starting to believe I have the settings dialled in perfectly on the control system.
My chilli plants are growing fast and looking great.
There is still an ongoing issue with high temperatures during really hot days.
I think the only way to rectify this maybe to look into putting in automatic vents in the roof.
I have ordered some serious 12V blower fans that will be arriving in the next few weeks, so they may help with the heat.
The new watering system is showing no signs of Algae in the water container, and the system is only watering at night as hoped.
