To all the customers who purchased from us. First, thank you very much for your orders We have finished all the individual orders, and there should be a tracking number that was communicated individually to everyone. If anyone did not get their tracking number by email ( the email used to...

nigritum is a name that was applied to dark barbatum in the trade, but it has nothing to do with the original nigritum, which came from Borneo specifically. There are some rare photos of real nigritum on internet, most on Japanese websites...

No, the sides always go backwards a bit... that's typical of the species.

The worst is that it seems that only the albino is alive of those Paphiopedilum nigritum, maybe 1 or 2 colored individuals more worldwide. They were a callosum/barbatum related species that was found in large quantites out of Sarawak in the late 80s to early 2000s. Many went to Japan back then...

Stress during the buds formation, it can be even when the buds were still deep inside the growth, not yet visible.

What happen if you open completely the discharge line ? Do you get a lower EC ?

So to fix your problem for certain, in a simple way, look at the page 9 The tiny blue pipe that goes to the ASO from the extreme side, remove it, replace by the long RO pipe from the left numbered number 3... This will be your direct line for the RO water production. It means that now you have...

I suddenly remember that once I had a RO unit that was not properly mounted. There is what they call an ASO valve, that was in fact mixing the RO water with the input one. Something that looks like that...

Wait a couple hours more just in case, but this is not normal if that value persists... Check if you cannot increase the rejected water flow rate in a way or another. Do you have photos of the filters and piping of your unit?

Actually the wide leafed ones without much red in the front are the hybrid of hookerae x volonteanum, that was produced in Hawaii quite a while ago... They have a leaf pattern intermediate between hookerae and volonteanum. Those were released as volonteanum by many resellers, very hard to tell...

Don't know if we live on the same planet, but just searching for emersonii on the USA eBay returned 3 sellers, and two with wild collected plants shipping from the USA as an example. It has been so since years for many plant species.

What I was unfortunately expecting... Calcium and Magnesium are removed with the highest priority, leaving the sodium. You definitely need a booster pump and re-analyze the water if the EC is not below 30-40 microsiemens... Another trick is to 'open' the pipe that releases the waste/drain...

Fusarium with a kind of 'crust' on top of the lesion. Usually it starts from the rhizome and crown base. In most cases it is hopeess. Eventually feeding and fungicides can control it for a while, but it is usually systemic. One typical point is that it attacks a side of the plant only usually...

Over 50ppm TDS is very bad for a RO System. We usually target a max of 20-30 microsiemens. Check 3 things: - The input water pressure must be at least 40psi, preferably higher. Below that, it does not work. - If the membrane is well secured inside its cartridge. Sometimes there are leaks. -...

That promises to be interesting, the plants will perform way better with the extra ammonium. It could go higher even. Some of the fertilizers used in the 90s and 2000s were even half ammonium half nitrate ( the Jerry's Wundergrow was a good example).

That's what I do... but producing internally the plants, just adding few motherplants here and there. If buying, testing, and selling, that would add about 10+US/plant... Countiing the virus infected batches that such a nursery would have to throw away on arrival. Viruses are not as well...

That's the problem as well. A lot through tissue culture The plants can be asymptomatic when they are young. Cymbidium usually show the first symptoms around the time they have a mature bulb or mature bulb + growth. Some infamous 'breeders' do clone their plants, discard the motherplant, and...

OFV will never be available as quick test, that's why it is so dangerous. Until recently too, there were only 1 ELISA type test, and it was not that reliable, with a lot of false negatives. It is due to the viral particle structure, etc... The only 2 ways strangely to detect it were electron...

That is the key problem, orchids and many plants can absorb and use directly urea. There are as well orchids that are unable to process nitrate nitrogen too. Some of the best TC Media for Phalaenopsis have only urea as a nitrogen source, as well as some ammonium, and a low quantity of...

You are right, it depends on the lab doing the multiplication, and its protocols. But even with a 'perfect' lab, when you are using thermotherapy or antivirals, you have a risk of mutation. I did Phalaenopsis on a very large scale, and to have mutation-free plants after 15-20 cycles needs some...
