There's been a lot talk about growing semi hydro (SH) vs. a soil based mix. Mind you, these are my results grown in a GH in my part of the country. I'll let you be the judge, but I think almost anyone, any where can grow most Hoyas SH. For my medium I use only expanded clay pellets, Hydroton, Hydro Corn and now Hydro Rokz which I love. As a fertilizer I only use Miracle grow at a rate of 1 Tbs. per 5 Gal. of water (every time I water).

The first set of pics is H. odetteae both were planted last fall at the same time, so are less than a year old. Pic 1, shows a side by side, pic 2, plant was started in a soil perlite mix, 4 cuttings 4 nodes each and is a very nice plant. Pic 3, plant started SH using Hydroton 4 cuttings 8 to 10 nodes each, was repotted to a chunky mix about 3 months ago.

The second set of pics is H. davidcummingii, they were started at different times, Pic 1, shows a side by side, pic 2, plant was started and growing in a soil mix 2 years ago, 2 cuttings 4 nodes each. Pic 3, plant started last fall SH using Hydroton 4 cuttings 8 to 10 nodes each, still growing SH, this one will stay that way.

The third set of pics is H. mac, they were started at different times, Pic 1, shows a side by side, pic 2, plant is growing in a soil mix and is about 3 years old, Pic 3, plant started last fall SH using Hydroton 2 cuttings 5 to 6 nodes each, still growing SH, this one will stay that way.

And finally H. cv. Mathilde, they were started at different times, Pic 1, shows a side by side, pic 2, plant was started and growing in a soil mix last fall, 4 cuttings 4 nodes each. Pic 3, plant started only 3 months ago SH using Hydro Corn 4 cuttings 8 to 10 nodes each, still growing SH, I will repot this one to a chunky mix in a couple months. .

SO,
The odetteae speaks for itself
davidcummingsii can be tough, but they do seem to like growing SH.
Personally I like the way the H. macs grow SH, they seem to grow lush and fuller with less tip dieoff
I like how quick cv. Mathilde rooted SH, I think I'll try it with H. serpens because I have a hard time with that one.
One advantage to rooting SH, in most cases you can start with larger cuttings, that will give you larger fuller plants in a shorter period of time.
One disadvantage, you will need to water more often, at least every other day and possibly every day, some even water twice a day.

Great post!Ive tried growing sh with hydroton in clear glass containers with drain holes 1 inch from the bottom,but it seemed like there was too much condensation around the sides of the glass,and the roots slowly rotted.I want to try again,so here a few questions.1:Will a hoya that is already growing in soil make a good candidate for sh?2:When rooting cuttings,are they out in the open,or do you put a bag over them for extra humidity?3:do hoys started in sh for a time then transplanted into reg mix do better than staying in sh?and finally,have you ever used growstones brand rocks and your thoughs about them for sh.I hear the ph is a little on the high side...I have some black containers I want to drill holes in and use for sh containers.Any thoughts would be greatly appreciated!

Wow. amazing plants in S/H.

I am starting an experiment with Growstones S/H... we'll see if the PH is an issue.

Thanks Jimmy,

To answer your questions:
1) I've switched over about 1/2 dozen with good results, the latest, about 3 weeks ago a H. dennisii that I almost lost, it already has new growth. Just clean the root ball and cover it with pellets ( the trick is) at first only moisten the pellets every day for about 2 weeks, after that then add your standing water.
2) I bag them for about 2 months, then slowly open the bag.
3) I do replant most of SH grown Hoyas into a very loose mix for resale at about 6 months old, all do very well, But some I will continue to grow SH.
4) At this point I only use expanded clay pellets which are PH neutral. Carol is working with the growstones, I'll see what she thinks over time, Then I'll decide.
I use clear and colored pots for SH so I think the black would be fine.

Jimmy,
I start them out in a regular pot with holes in the bottom and pour the water straight through so everything gets wet.

KIM - GREAT POST!!!! Wow...this needs to go on the forums and chat rooms!!!! What are Hydro Rokz?

Have you tried setting the pot with the Hydroton in a dish of water and letting the beads wick the moisture up? I find that works really well and just replenish the water in the well...actually I pour the water thru the pot of Hydroton until the dish underneath is full.

I am REALLY like the Growstones!!! They retain the moisture beautifully...much better than Hydroton... So much better that I don't put the pot in a dish to wick up...but pour the water thru every other day. This is for rooting Hoyas.... I have some great photos I will post tomorrow - just came home from a trip and am getting organized.

BTW sending you a Cmail tomorrow..... I tip my hat to you. Group hug

Great post Kim!! Your comparisons are excellent!

I confess to rooting all my cuttings SH now - and am about to return 2 which had beem potted up into regular compost, back to SH. Some plants just seem to love it!
Thanks for your great info. I tip my hat to you.

Carol,
Just got back from the airport, give me a couple hours and I'll post a pic. Their like The hydroton more uniform and round unlike the hydro corn.
I do use a dish under the pot to.

If you have some 'grow' stores in the area, check with them. Will go to mine today and see if they have this.... Thanks, Kim!!!

I am using Growstones and like them a lot. I've had plants in them for about 5 days. Nothing is dead yet. I have some new growth on several already.

I put the stones in a huge pasta pot with water. I put in fertilizer at 1/3 strength (Orchid type), along with a tsp of baking soda to help with the Ph. I lay a plate on top to keep them in the water.

****
PLEASE NOTE: Baking Soda is exactly the wrong thing to use to adjust Ph down... IDK what I was thinking.

PHOSPHORUS will lower Ph -- and many Orchid fertilizers contain phosphorus. Check with your fert manufacturer I guess to find out how much you would use to adjust Growstone Ph from around 7 to around 5 for, say, a gallon of premixed soaking solution (if Ph of 5 is what you are aiming for)

I also posted this correction below in this thread.
*****

Then I just scoop them out for planting. They stay wet for a while - if you rub one on your lip you can feel it even if you can't with your fingers.
