Semi-Hydro versus Water Culture?
 
I just re-discovered the Vengers Water Culture site (I had seen it a long
time ago, and I think that's where I got the idea that orchids must grow a
new set of roots to thrive in water?)

http://www.vengers.com/culture/water.htm

Anyway now I am wondering about "water culture" versus semi-hydro. Is
semi-hydro an improved version of water culture? How do they compare /
differ? If I understand correctly the vengers water culture site suggests
growing orchids just in water without any clay pallets or anything like
that. And then the algae growth is considered really beneficial in water
culture, but I don't see it in the semi-hydro basics
(http://www.firstrays.com/hydro.htm) from what I have read so far. But I
would like to know more.

Is anyone still growing in water culture? (The vengers site seems to be from
the 1990s, and I have not seen people refer to "water culture" recently, so
I ask.)

Semi-Hydro versus Water Culture?
 

I have some plants in water culture. I use it mostly to save plants
that for one reason or other is dying. Water culture does not always
work to save dying plants. Some plants just insist on dying. BUT, as
a method of growing orchids, it no doubt works.

Is it "better" than Ray's semi hydroponic? I don't know. In fact, I
am about to start some plants on semi hydroponic. I will find out if
one method is better than the other. I THINK it is going to be a
matter of personal preference.

Personally, I don't like the way a plant flops around in water culture.
I find it hard to keep a plant supported in water culture. Water
culture does work, but under-water culture of orchid does not. Trying
to keep only the root zone submerged on different plants in different
containers requires quite a bit og attention to detail.

Hope this helps.

Semi-Hydro versus Water Culture?
 
Joanna,

The two are totally different concepts.

Water culture involves maintaining the plants' root systems totally
submerged in a nutrient solution. According to Rod, the algae is
more-or-less necessary as it consumes the nasty-smelling byproducts that
accumulate in the liquid. He also found that he needed to keep the
containers on a heating mat (at least in colder weather), maintaining the
water at 70°F or rot would occasionally set in.

Semi-Hydroponics involves using an inert growing medium in conjunction with
an individual-plant reservoir of nutrient solution that travels upward in
the medium by capillary action. Algae is an S/H pot is not necessary, but
often occurs, as it will anywhere there's light, moisture, and nutrition.
It's easy to prevent its growth via any number of treatments.

The only time there's the slightest resemblance to water culture is when the
plant sends its roots down into the reservoir...

Ah, interesting! I guess I must have not read your semi-hydro page carefully
enough to get it, sorry. Out of some reason I had misunderstood and thought
that the entire plant container was filled with water and this PrimeAgra
stuff. And so then it sounded very similar to water culture. Whereas now I
finally understand that it is indead very different. Thanks for clarifying!
