Go to firstrays.com - there's a whole section of info on s/h culture.

I am convinced that any plant CAN be grown that way, IF it works well with the rest of your growing conditions to meet the needs of the plant.

Hi Ray,

thank you! I've already read all the information on firstrays.com - twice or more

Thank you so much for developing the method, the info, and sharing with us.

I decided to try it when I saw this site

Growing Angraecum Orchids Using Semi-Hydroponic Techniques

I now have, in standard S/H plastic containers, an Angraecum sesquipedale, Paph rothschildianum, Paph Onyx, Paph Pinocchio and a NOID Phalaenopsis that are going gangbusters. Some Cymbidium and Oncidium seedlings are doing well. A couple of Cattleya seedlings looked bad for 3 months but have begun new growth recently.

I just put some Bulbophyllum and an Oncidium into S/H, but with clay pots I stand in dishes of water for the evaporative cooling effect. They look good so far.

It is very important to read Ray's instructions, and move plants only when they are actively making new roots and growth.

Out of curiosity, why would you want to cool plants - bulbos and oncids - that are generally warmer-growing?

[estación seca]

Cooler-growing bulbos and Odontoglossum lacerum. The warm stuff is in your 1 quart S/H pots.

That list is a waste of time, and not worth reading.

ANY orchid - any plant, actually - can be grown in semi-hydroponics, but that does not mean that YOU can grow any plant that way!

I - with more S/H experience than anyone - have never been successful with dendrobiums, yet many tell me they're the ideal beginner's plant for the technique.

There is a lady near me who is into orchids, so has changed her entire collection over, but she is REALLY into cacti, succulents, and caudiciforms, and win is all kinds of awards for those in S/H.

We have an OS member that grows her orchids hydroponically. I had trouble growing tomatoes hydroponically. :|

I've also been growing an aglaonema in s/h with good results. I'm also growing three different pothos plants in PrimeAgra using the s/h method and they really love it. I experimented with some sansiverias and they hated it - but they are plants that like to dry up between watering so, so no surprise really. I do have a sansiveria in PrimeAgra, but not using a water reservoir and allowing it to mostly dry between waterings - it's doing pretty good. I just started to try a Schefflera in s/h last week, we'll see how that goes. I like the idea of the water globe, that would be great for when we go on vacations.
