semi-hydro compared to gritty mix
EDIT Jan 28, 2015: this is an old thread, but I updated today with the results of that rooting / growing/ blooming experiment. Check it out below. The text or the original post follows.
As somebody who has been growing hoyas in "gritty mix" (pine bark, turface or calcined DE and granite grit; pictured), what am I missing, if anything, by not going semi-hydro for at least some of my hoyas and maybe other plants?
I've read/seen very positive reviews of semi-hydro method, but with gritty mix, I am kind of largely there already - very good aeration, instant drainage, but with some water retention in the mix. There is no pool of water to wick up from though - roots just get the water+nutrients from retained water like in traditional pots, but you know, minus the suffocation.
So, I am interested particularly in stories/opinions of those who tried both s-h and gritty mix.
It can get pretty dry here in the winter - I may not be able to water enough in semi-hydro. How often do you water indoors with central heating on?
I posted a more general s-h questions here (http://forums2.gardenweb.com/forums/load/houseplt/msg0203092013139.html), but I want to get hoya crowd's opinions in particular. Thanks.
