I don't understand your question. In ebb and flow, the tray is usually dry and then you flood it a few time a day.

about 15 mins every 4 or 5 hours duri8ng lights on, if your doing 12/12 then every 3 hoursn or so . . . . if your timer has smaller time segments than 15 mins then set it so it floods , runs off for a minute or 2 then drain . . . . . dont water in lioghts out . hope this helps

my ebb and flow system is a 50 gal res that pumps into a control bucket which has a timer box and a series of floats .. i water for 30 min 4 times a day because i feed lots of plants. 15 min is not enought time to soak it all up and give ample time for them to drink.

Granted , but for a 4 x 2 x 2 tray 15 mins should be ample, its a starting block and you adjust to adapt to the plants need's , if your plants need more time up the timer, if you're only growing say 4 plants with one tray in rockwool/hydroton 15 mins is ample , all you need is to submerge your medium, allow a bit of soak time and then drain off . . . overcook it and it can damage yr roots . . . putting her into shock, and that sucks . . . . my clone is doing fine on 3 15 min floods in an 18/6 light cycle . . the drainage is more impoortant than the flooding

yes will start at 15 min, i didnt think just flood and drain could feed it right ! cool.thanks

i missed the fact that you had a small tray.. i have 2 gal buckets .. lots of them so it takes 30 min even to fill up

I can't even pretend to be an expert in this field but I've read about a million things on ebb and flow most will say with a small
Table 15 min should be total time from start of flood to final drain. I can say be very careful with seedlings in this type of system
It can be desasterous for little babys I've been fighting nute burn and overwater since I started. I think though since I'm in actual
Veg stage now my troubles are about over small system maybe 3-4 times a day total flood and drain time o 15 min should work but like said
Above if need more time just set timer up a bit . Just remember baby steps never make drastic changes slow and easy they will thank
You for it later good luck
