Nope - Same way for synthetic runs.....I have never been a fan of run off.
I hate how soils can shrink up and let water/feed just roll through it if it gets "too dry"..... Products like "Drip Clean" turn your soil into a "brick" and should be avoided.
15-20% run off is simply waste. Watering like that doesn't really bring more to the roots as far as they need by way of O2. Simply watering to a "drop" of run off is plenty enough to bring the roots O2.
I rely on a balance between my Temps - RH and amounts I feed per pot on a daily basis to build my rootballs....
As far as cleaning away any "build up". I don't feed enough for it to build up. I do feed to a minor "push" too.
This is just a simple friendly reply to yours, as to what I do vs. and why.
Can you explain the aversion to Drip Clean? Why does it turn soil to brick? Just curious, as I use it all the time and thinking of not using it on every watering but instead on a once-a-week basis as a weekly flush of sorts.
