Like all other fungal infestations moist conditions are optimal for root rot manifestation. Wet conditions for a really long time with no proper air movement can prompt root rot and effected plant will be dead in no time. Hydroponic plants more often susceptible root rot because of their acquaintance with more water or soggy warm conditions. You will observe discolouration/yellowing of infected vegetation as well as burnt edges of leaves. Besides this stunted growth of plants can also be a indication of this disease. If roots of an infected plant are observed ,prominent dark color and delicate roots rather than white healthy roots can be seen, that confirms the detection of root rot as shown by its name. Hydroponic growers need to detect and control this infestation before it may kill all the plants.
