Dave Depends on the type of system. With a flood/drain system you turn off the auto timer and watch until some wilting occurs before restarting the pump cycle again. With something like a "smart valve" system this occurs naturally (there is no nutrient topup until some drying out has occured). Nutrient film technique (NFT) - once again you turn off the circulation pump for a while to stop nutrient solution and cause some drying out. With all the above you need to watch pretty carefully as the media used in most systems has very little buffering capacity and the line between stressed and stuffed can be ten minutes. So overall, letting them "dry out" means withholding nutrient solution until you get to the point you want!. Cheers from the Hemisphere where growth is underway.

The way I stress my garden grown plants is to withhold water. How do you do this in hydroponic medium? Do you let the hydroponic medium evaporate?
