A few questions for the gurus... 1) When HC is grown using they dry start method then submerged, is it more likely to stay low to the substrate compared to conventional submerged methods ? 2) What is the rule of thumb for when to trim the HC? Do you wait till it reaches a certain height or wait till the HC entirely covers the substrate? 3) How short do you trim it? I was told in one forum the Amano trims them down to the bare root My tank - ADA 60P Iwagumi style (HC, Bylxa, a few Anubias petite from an old setup) with Amazonia II, 150 Watt MH lighthing, CO2 suppl. My HC lawn is about 3 months old, 1" high after recent trim. Decided not to trim more off bec I discovered baby tiger shrimps hiding under the lawn, so I tried not to disturb their hideout too much.
