When using a flood and drain table do you need to use a top sheet cut around your plant pots to stop the nutrient solution being directly under the lights during the flood cycle?

Thanks for any help

And this causes no problems with the nutrient solution warming then?

Thanks

my room is 66 night and 71 days. solution says @ 66-70 this is ideal temp. dont let your nutes get to the 80's. it will start to go sour on you

Thanks for the help, I just wondered if the light on the nute solution was any probs.

In the one I'm looking at the tray covers almost all of the res with very little gap either side so that should be ok i guess.
