He who loves his orchids will only consist which is hereby found;) I have all the windowsills full and formerly also like to buy low-priced substrate times due to the mass. In the normal retail or DIY Seramis is already the most expensive at the normal price. Unfortunately, it thanked me my plants nicht..mehrere rotted despite the fact that I just treated like everyone else. Then I switched to this substrate and even the most vulnerable survivors. Just relax and pot plants in summer 1 times a week, in winter every 2 weeks diving for about 20 minutes and the orchids will thank. Many flowers, new flowering shoots and little more to costs for the substrate one takes gladly accepted.
