Does anyone use this method for their orchids?

I did use what is known as semi-hydroponics a few years ago but it didn't go well with my Catts.

I tried the semi-hydro method years ago, too, but i don't do it now. I've never been brave enough to attempt full water culture. I have seen pictures around (on Instagram, mostly) of people doing it successfully (at least by their own standards), but I don't know how the plants would respond to permanent water culture. I can't see it working long term as orchid roots don't respond well to being kept in water as a rule. I suspect if you could keep the water actively aerated you might do OK with it for some genera.

I tried it with some seedling vandas probably 20 years ago and more recently several doritis. It works as long as the water is fresh, and the weather is warm and sunny. Not so good for english winters, even in a heated greenhouse.

I noticed a few days ago our local tesco were selling some nice glass vases for orchids for 2£ each, so im trying water culture on some vandaceous types which i have trouble keeping watered enough. One thing i'm sure of is it wont work over winter.

Thankyou all I am trying out this method with one of my phals as it had stopped flowering.

Hi Scotkat,

When was the last time your phal flowered ?
Has it genuinely stopped flowering (as phals are usually reliable flowerers)....... or just not flowering as much as you would like (two totally different things !).

I haven't tried the full hydroponic method but a bit of a hybrid, the clay balls mixed with the smallest amount of compost and treated like ordinary bark media, watering once/twice a week. Me and my plants seem to be happy with this as they are all growing and flowering well.
Two restrepias in clay balls only and sitting in a saucer of water, also with no problems and both in flower right now.

My only concern is that if you are interested in trying the hydro method and use a "suspect" plant, you may get a false result which could affect how you treat your plants in future, positive or negative ?
If your phal is a prized specimen, I think I would probably be tempted to try to get at least one of those knock-down priced, out of flower phals to experiment with before jumping in with my main collection.

Steve

I have been using clear glass with clay media for a year now for phals, oncidiums and dens.
They are all doing well. My glass vase has no drainage holes. I maintain less than 2cms water level.
I got my vase from Ikea and the clay from Amazon.

I've never managed to make the leap into 100% hydro-culture, it goes against everything I've been taught about plants: "free-draining", "better too dry than too wet", "never overwater" etc....
But I know there are many success stories like yours and the theory makes sense, might try on an old reduced Noid or two sometime?

I got my mum to pot her badly dehydrated phal in a glass vase and it showed a big improvement, flowering and roots are growing, looks a lot healthier.

Another Hydro success story, that's what we like to hear !
