Anyone grow in Hugo blocks with top feed?

Morining all. kay so I'm sick of manually feeding but dont want to overwater with a timer seeing my minumum cycle would be a minute at a time. Ive read that the shot size for the block is around 120 ml roughly .. I just got 1 spaghetti line stuck str8 into each block. Tried the drippers from bunnings they are shit I'm about 5 weeks into flower . tell me your watering cycles people I need some idea I just give them a squirt in the morning for 20 seconds 3 hours after that another 20 second squirt and then a runoff squirt 3 hours later.. Whatever I'm doings working its just annoying..

Some info for shits n giggles

600w 1x1x 2m tent hugos on a flood tray 6 inch iso max
4 inch intake
Rh ranges from 40-50ish through the day
Can spike to 65 max at night but average 55
12 inch fan keeps everything moving

I've defoliated nicely ( they loved it..for those who hold them precious). lol..

think I have about the optimum amount of heads for the size tent anyway bit tight so I will be cutting it to 5 on the next run if I seed or 9 if I clone

Put a ball valve on your main line and throttle the flow a bit, or use a less GPH pump and use the 1 minute interval you can setup with the timer you have.
