How soon should I see run-off during mid-bloom in rockwool hugo?

Hey everyone,

I am currently in day 35 of flower (bulking stage) in 6x6 rockwool hugo blocks using a top feed DTW floraflex (open bubbler) setup. I am not using any substrate meters, but I plan to in the near future.

I'm feeding 100ml shots every 45 mins,1 hour after lights on all the way until 1 hour before lights off - total of 14 shots. Currently achieving runoff around the 9th feeding or late afternoon about 6 hours after the lights come on.

Any idea as to how soon I should get runoff during vegetative style irritations during mid bloom(bulking)? Is there a golden hour as to when I should see runoff? Should I adjust the first irrigations to 30 minute intervals to achieve runoff sooner?

Thanks in advance for your help.

why are you feeding 100ml 14 times a day?
I feed 2 or 3 times a day at most in full flower.
last run was 2x daily and it was pretty light by the second feed.

I'm new to rockwool, currently trying vegetative irrigation crop steering methods - this is my second run using rockwool. How many ML's are you feeding per shot?

I am not on a drip system just to be clear. Using a open flow bubbler from Floraflex.

Following this guideline from Floraflex. They are feeding way more than 2 or 3 times per day.




Like I mentioned in the original post, I am doing this without any substrate sensors. Essentially guessing my way through. Any useful advice would be appreciated. Thanks.

doesnt look like thats for stonewool. clay pebbles in a 1 gallon pot maybe?
I feed until the timer stops.
drip irrigation until run off.
