Second was the same way but no hydroton which I made a few mistakes by not letting it fill up at least 3/4 of way of the tray. So I switched to 6" baskets with hydroton inside the baskets along with 3-6"x3' water bags on the sides of tray. Now with a 20gal res it fills up in 5 minutes up to the top of basket. Also make sure your overflow valve is higher so it take longer to fill up. Like anything else, its trial & error & works for some & not others.
I switched to a 55gallon res. and it works fine.
kingucci Reviewed by kingucci on . What size res. do I need for a 4x4 flood table? I have 2 4x4 flood tables and two 30gallon res. The guy at the hydro store told me that 30gal. res. was enough to fill the table and when I ran the pump it only filled up to half way up the table and the pump started to run dry. So im guessing I need a bigger res. Also, it takes about 5min to fill up the table half way.. and 10-15min to drain. Is thier timers that turn on for 5min. and off for several hours?? I have a 3on/off timer but It cant be turned on for less than 30min. So what timer Rating: 5
