Hello guys, I've moved over to flood and drain and just having to work out the flood time settings, let me explain where i'm at. I've grown from seed at the moment snow white in rockwool they have roots about 3 inches long out the bottom of 3 inch net pots and are about 3-4 inches in plant height. I was flooding 5 times a day for 15 mins at a time, the leaves were dropping down so a classic case of overwatering. I've now set the timer to do only three floods a day for 15 mins so hopefully this will correct and improve the droppy plants. My question is once they get bigger and stronger will i have to increase flood times as i go along this is the bit that i'm unclear about ? What do you guys do that use flood and drain, any help appreciated as this is a new system for me...''
