Yesterday I potted up 3 more flasks, time consuming but worth the time and effort if they grow. This is one of the flasks, the plants were the largest I've got from a flask before:
The next picture is a close up, there are large plants in the jar but if you look closely it's as if all these tiny plants started growing as an afterthought, it's a shame as I had to throw them out. Any thoughts on what would cause them to start growing so late?
There were nearly 50 plants in the jar but only 44 were suitable for potting up. The others either had no roots or was just too small, don't tell my wife I had them on the kitchen bench when she wasn't home:
Finally this is how I grow them, in plastic storage boxes individually potted up in 2 inch pots. They grow in fine bark. There are 3 flasks here (with one flask going across two boxes) - two flasks of cattleya hybrids and one flask of paphs.
I just wish I could get the roots to stay like this, they grow well during summer but die back in winter but I guess that's supposed to happen:
