Why 4 times a day.?! That seems a lot. You wouldn’t water your plants 4x per day.

The flood cycles will depend on the media used to grow the plants in. The more coarse the media the larger the pore spaces between the individual particles. I’ve found with 5mm (1/4”) gravel flooding four times a day gives great results. Flood and drain works by filling the bed almost to the top, pushing all of the air out. Then draining, drawing fresh air into the root zone. Leaving a meniscus of nutrient solution on the roots and media. Then before the roots dry out and start to die, the flooding occurs again, on repeat. I’ve also grown flood and drain in expanded clay media, flooding every hour, as the media is more coarse, more frequent flooding is required. In watering plants in soil, some of the soil particles hold water, clay, loam, organic matter all hold water. We have cacti and succulents that only get watered once or twice a week.
