Hi Not a Number,
Thank you for the listserv posting. It is interesting to see that someone has tried, and apparently had success with CP hydroponics. I did contemplate an ebb and flow system but they are typically more space consuming and a little more complicated to build than DWC. I'm also interested in the fact that he had success with passive hydroponics on Nepenthes, as I have tried this in the past and was not very successful so it may be worth a re-visit.
As you can see from my VFT hydroponics experiment, the plant is still alive and growing - though now in winter dormancy - so I find it interesting that Barry has found hydroponics not to work. There are many different types of hydroponics though and a myriad of different nutrient solutions and additives, so it is possible that some may work and some may not. Ultimately time will tell if my plants survive, especially over extended periods. The VFT has only really had half a season in hydroponics so who knows what might happen to it when the season starts again next spring.
