    Recycled a/c water is safe for orchids?

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...

    Marble chips on Kovachii's potting mix?

    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...

    Marble chips on Kovachii's potting mix?

    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...

    Marble chips on Kovachii's potting mix?

    Dendrobium spectabile

    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...

    Dendrobium spectabile

    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
