hydroton vs. prime agra?

As to the nobile dens question, there are two schools-of-thought on that:

1) Withhold all water, as you would in "ordinary" culture, or

2) Water normally, but with plain water only, withholding all fertilizer.

Apparently both work fine.

Interesting.. withholding fertilizer? This might be a dumb question but what is the rationale behind the effectiveness of that? As a matter of fact.. why do we need to withhold water anyways? Never knew... just did it and it worked fine for me for flowers.

Wow! Missed this one....sorry.

My understanding is that the presence of nitrogen spurs on the continuation of vegetative growth, and stops blooming from occurring. I suspect that "not watering" is just a way to not feed.
