There seems to be so much confusion on terminology it might be best if we make an "aquaponics definitions" page to go along with "what is aquaponics" and "rules of thumb" on the home page.
No goosing in aquaponics. Gotta let nature take it's course or you likely pay. Now I suppose some one with supplemental filtration to support the fish might be able to change the cycles but then you loose the whole efficiency of the plant bed also being the filtration.
I'd say if some one thinks the plants are looking poorly and they think it's cause the plants are not getting enough dry time. Add more aeration to the water and you may see the plants perk up without changing the cycles at all. Heck, I've seen plants looking really good in constantly flooded beds provided there is enough flow and aeration.
