@chihayan how did you do that that is incredible to do the split screen thing but where are you from.

I use iphone app InstaMag for split screen and use RookieCam for the letters and drawings.
I'm from Japan, Chiba prf.
How about you?

i will try it but i could have done it with my spider plant.i am from the us,new england,ct,new britan.

I made a mistake to understand what you meant.
you want to know how did I success with hydroponic of haworthia, don't you?
it is not so difficult.
you can start hydroponic of cactus or haworthia very easy.
just clean their roots in water and cut the roots off shorter. then dry it out in a few days.
set the plant on water, the end of the roots touch surface of water just a little bit.
not damp.
keep warm and bright
you can see some new white roots in weeks
cacti and hawo are good for hydroponic
but most Succulents need full sun and full sun makes water too hot.
hawo don't need full sun so they are good for hydroponic

@cory in the house http://www.ehow.com/how_8582179_grow-cactus-hydroponically.html

can i do it with a bladderwort.

I'm not sure. 'ひろき' in this app greensnap trying to make hydroponics of frytraps last summer but he is not active now.
if you have some bladderwort, just try.
you don't, I think you may not try to set hydro.

in the latest a year i should have a type of carnivorus plant but i will save money to buy bladderworts and look up an online tutorial on how to grow it hydroponicly.

the reason why it didn't work for him is because flytraps are electrical and the water didn't allow it to eat so that was a really stupid idea for him0
