This can be tricky. The Tall Garden above is an example. Plastic sheeting retains heat inside the greenhouse during the day.
The nutrient solution is changed either on a schedule, such as once per week, or when the concentration drops below a certain level as determined with an electrical conductivity meter. The amount of leachate is increased to decrease the EC in the slab, while a small amount of leachate will usually result in higher EC's in the slab.
