Depending on the growth.

My Plant in 12 L drinks nearly daily 1L it is water - feed - no water.

I have nearly no run off and the bit I have is sucked in 30 mins.

But if small it does need less.

Bottom watering takes two hours to suck in but prevents fungus flies.

The best solution to fungus gnats that I have ever seen is very simple, cheap, and works 100%.

BTW, I answered you questions in the other thread where you asked me originally.

One cautionary note, coco NEEDS to have runoff to flush excess salts from the media. I aim for 20% or more myself just to keep the plants thriving and growing fast. If you don’t flush the coco the growth rate will be significantly slower because the roots have to deal with waste salts buildup.

As a rule of thumb I always over do the feed quantity wise, I get way for a 15 ltr pot I normally feed 5 ltrs per feed, that way you wash all the old and replace it every day good and proper, and I never have any deficiencies, correct ph is the key I feel to getting the feed right, the plant will do all the work once everything is provided and the correct ph is giving the plant the correct tools to do the job 

@green-beard Yes I am very carful with my pH! Thanks! 

@monkeydo yes I understand runoff is very important!

I have been watching videos and diff watering techniques, also started to practice ahead of time with ports filled with just the media, Ill get a hang of it but I will always aim for runoff to flush everything out. My new babies that Im going to grow have just shot out in my seedling station, during this stage should I still water till runoff? I have seen people that say just to spray a little water with an atomizer during seedling stage. 

Thanks!
