Hmm hard to tell it depends on your conditions and type of orchids i guess. My
Renanthera, Vandopsis, Papilionanthe, Luisia are all in leca and I water them daily
exposed to full sun.... while my other plants, Paphs, Phals, Coelogynes, cmybids, Erias...
they are also potted in straight leca and are watered every other day.
But this is what I noticed, as long as the plant is not over potted.... its difficult
to over water the plant since the media is very fast draining. The drawback would be
is that nutrients are not freely available to the roots. I fix that by placing a few
pellets of osmocote. I also have a Onc. Sharry Baby and Paphs in S/H and theyre doing great
as well. Another drawback would be when the pot falls good luck picking them all.
I tried nylon net around the top of my pots of Leca and found the orchids send their roots through the netting. Gotta cut it off the pot when you pot them up, but it does keep most of the Leca corraled if the pot tips.
Like Randy mentioned earlier, what if you accidentally topple the container? Hahahaha! I can just imagine trying to catch and pick up the rolling Leca pellets all over the floor running in different directions? I had this hilarious experience once while re-potting a plant in Leca in my front patio. The floor there is inclined as it was originally designed to be a driveway, slightly tilting towards the gate and into the main street. Golleee as the pellets started rolling down and I was running with a broom trying to prevent the precious Leca from going into the street and I went out of the gate shirtless, neighbors were looking strangely at me! Geesh!
I am wiser now and when I re-pot using Leca I do it within a large aluminum laundry basin to act as my catch holder in case disaster or clumsiness strikes again. LOL!
The only thing I observed regarding the kind of Leca that is available in the seed bank is that it appears not to be of extremely good quality because a lot of it floats when submerged in water. Each time I buy a new batch of Leca, it is my habit to dump them in a large pail to soak overnight and wash them with water to remove the harmful elements that might be present during its production. I notice that 50% of them float so it is difficult to wash them properly without losing some out of the pail.
I read in the S/H section of this forum, it is mentioned there that the really good quality Leca should'nt float and they stay in the bottom as they suck up water via capillary action upwards towards the plant roots. That's why they mention there certain branded forms of Leca like PrimeAgra which unfortunately isn't available this part of the world. So I guess we're stuck with our own Philippine Leca (or wherever the MSBF sourced them from .... perhaps Taiwan or China????)
Sometimes I would add a little organic, plant wetting agent to the water so that the LECA would imbibe the water more easily and more would eventually fall to the bottom.
Just what I have observed ......
How about the hydrocorns bought at miura plants? They are kinda expensive. Is it worth the money?
Where/What is miura plants? Are these the small plants that I see complete with container and hydrocorns all packaged and sold at the malls?
I think those hydrocorns look the same to me as the ones that are being sold in the seedling bank.
the dwarf ornamental plants seen at the malls are called miura hydroplants very expensive, they say that the pots are a special one, price ranges from Php 300 for the very small pot up to Php 1,600 for a 6" pot plants, according to the outlet that i ask.
Of course to the uninitiated general buying public this is a novelty and arouses their curiosity and interest and since it is being sold inside the malls, regular buyers would think "Hey! this is cool!" and they just buy, buy, buy despite the cost ..... you know, packaging and design does sell ....
they are marketing it as a hyrdoplants suitable for office, to aide in cleaning the air without mess
i was really amazed then when i saw it, and would love to buy one for my office desk, but when i learned that the price is beyond my reach, i easily left, thinking that there are more ways to have an office desk plant at a lesser price.
