Thank for your comments. I share the idea it could be a P. Grande and I'll mark it in this way. Inviato dal mio iPhone utilizzando Tapatalk

Hello everybody I must bring this plant to an orchid show next weekend (not to be award) but I'm not but is it's label correct. My label is phragmipedium humboldtii. What do you think. Any suggest is well accept. Thank you Luca

Thank you all for your contribution Luca

Dear friends I have read discordant opinions about use of recycled water from an air conditioner. It's positioned in the greenhouse, so during summer months it produces more than 5 litres of water everyday. It helps me to keep inside temperature under 30 C and a fog system provides to keep right...

No, N on Akerne Rain mix is essentially nitrate. It has less than 1% of ammonium. Luca

I have done, but in any case they tend to stay in lower part of the pot Luca

I thought that Kovachii needs low nutrients, I have some other pk hybrids that are grow in same way and they grow well. So do you think Kovachii species must eat more? I'll do in this way. I'll begin to add one feeding with calcium nitrate and Magnesum sulfate. Can I mix them togheter or is...

I fertilize one time a week at 250ppm (total), using 90% rain water and 10% tap water. Ebb and flow system runs one time a day for 15 minutes with pure rain water. I agree with you that new plant had more nutrients, my doubt is if mine cannot assume all nutrients due to some deficence Luca

I'm asking about symptom of calcium deficence, because I'm trying to understand why my Kovachii have bright green leaves, instead of dark green, leaves are thinner and softner than usual plants I have seen. My fertilizer is K-lite alternate to an european version of Msu, both with calcium...

Thanks to everybody @ Gonewild I know that Marble is less reactive. In any case i have put a small amount of washed marble chips in a cup of pure water (22ppm) and after 4 days ppm is 53, so I think that something has been released. Using oyster shell the problem is that they are wash out...

Dear ST friends I need an advice on Kovachii' culture. I live in Rome, a big city but far from limestone quarry. I'm not able to find limestone chips, but I have found Marble chips. This is chemical analysis CaCO3 97% Ca 37% Sio2 0,38% First thing hard to understand is...

Try to give it more lights and check if every new grow is at least high than previous one. Better is if it's higher Luca

I keep it in an intermediate greenhouse, giving a bright light, more or less like cattleya. Potting mix is very draining, with medium bark, leca and sponge rock. No rest period, during growing season (spring And summer) i give a lot of water and feed, 2 times at week. 1 time during rest of the...

Second bloom, but really nice this year. It has 8 spikes with about 100 flowers. Photos aren't best, but it's not easy to do them, cause spikes are in three different sides. Enjoy Luca

Very good results Ray. I have read you apply Kelpmax @ 1:128. Have you rise the dose? If I'm not wrong I remember you use a rate @ 1:256 monthly. Luca

This is the photostory of a repotting a phrag. Sorcer's apprentice. I have it since 2011 and last repot was in 2014. It's not easy to find best time to do it, cause when flowering finish, a new spike is already ready. For this reason I missed it last year. This is plant in full bloom last...

Rick, I've seen you grow all your posted paphio in basket with moss. Is it just moss or do you use some other medium inside the basket?

A nice vandaceus from south-east Asia not common in collections. Very fragrant flowers but short live (about one week)

Do you grow it in an ebb and flow system?
