Hi
If you use a soil based fertilizer for hydroponics you may have some
deficiencies such as magnesium etc.

The ph may need to be lower (acidic) than normal soil growing or the
plant may not be able to access some nutrients (some become unavailable
due to ph)

Other than that its a great easy way to grow plants

Hi

My mum has an indoor plant that is a sort of vine growing all around
her
lounge room, held up by hooks on the wall. The interesting thing is
that
it's just growing in a tub of water, doesn't get fertilised or
anything,
and it's massive! It can be propagated by just cutting a bit off at a
sort of node and roots grow from it. Does that sound familiar? Is
there
any other plants that can just grow in water like that? My hubby has
pineapple tops sitting in water and they've sprung roots and are
doing
great...I've also seen a white butterfly growing in pebbles in a tub
of
water. Is there a good way to fertilize them, given the water isn't
usually changed? I don't know if it would be good for them to sit
permanently in a tub of soluble fertilizer...

Thanks for your help - this looks good to me, I have a very black
thumb
and plants that are happy to just sit in water are right up my alley
:-)

Audrey-

The common climbing indoor plants include Devils Ivy (scindapsus
aureus),

,syngonium podophyllum http://hiloweb.com/webman/arr.html
and philodendrons

I suppose any of these COULD start as a cutting in water & grow just
like
with hydroponics. Make sure the water doesnt get cloudy/smelly.

I'd use a small amount of Miracle Grow as a fertiliser.
