I seem to have come up with an idea to eliminate the differences in watering. If I take the rockwool and cut it between the holes, making it non-continuous, maybe even adding spacers, each section would retain water.
Otherwise, the wall is more or less useless except for one or two spots.
The gigantea is still alive. I have been able to propegate it via leaf cuttings. All I do is place a leaf on my counter and wait until it shrivels. At the end hang miniature plants. Even easier than Joseph Clemens's method
I almost think 1/2 a day of sun is (not too much) not ideal for the plant. I have tried to get a ping that would grow well in my conditions. It grows OK, but stays about 4" in diameter. I have a humidity of 40-60%. Perhaps, the soil is not favored. I posted the mixturem proportions a while back. The new pinguiculas I have planted (not on wall, they would die right away. It takes a large pinguicula to be able to adjust. I ordered a plant from Flytrapshop and plopped in in the 2nd hole. It slowly withered away despite being largish, almost making it but not quite big enough to root.) I have put in peat/sandor vermiculite to see how big they get. I am also starting them under shade. I killed my last batch by placing them close to the mother plant.
In short, this is still a work-in-progress. I am actually thinking of abandoning the wall since I do not have enough plants to fill it! I will resist the urge and grow my stock. Hopefully to fill the wall sometime soon.
I do question the media I have used though. It works, obviously, but could work better. I have tried transplanting small plants to it (mostly cat litter) and they have not been able to survive. I am not sure why. The mix is very claylike when waterlogged. Perhaps I should use a mix with less cat litter? Jeff, can you advise an ideal recipe? Eric at World of Pinguicula uses this recipe:
2 perlite, 2 vermiculite, 1 pouzzolane (lava rock), 1 aqualite (can be replaced by one more unit of pouzzolane), 1 fine sand, 1 coarse sand, 1 calcareous clay. All well mixed.
Should I modify that to be better suited to P. gigantea?
