DIY flood tray

I made a flood table from plastic, cos no local hydro shop sells the size I need (4x8ft). Made it hermetic etc... It can hold over 100 litres.
Never used such thing, so now trying to figure out how usually do I need to empty it from the runoff water? So that the infection does not have enough time to develop? I water about 40 litres a day till it drain about 20%

Pots itself stands on a plastic platform (3 inches above the bottom of tray)

You're not doing what's referred to as flood and drain which would require pumps, a reservoir, a method for oxygenating the nutrient solution, etc... You're doing a standard watering to runoff and capturing that runoff to discard later by removing it with a shop vac. Basically a manual drain to waste setup without a drain.

You do not want those plants sitting in that stagnant nutrient solution for any amount of time.

But pots are lifted, so they don't touch the excess nutrient solution, I am emptying it once a week, hopefully I dont get any mold...
