Well, apropos of a recent thread, I decided to start a new one here that is on-topic, of that off-topic discussion
When I was first starting out, in all the instructions I found, the proverbial 'they' described a certain potting medium, certain humidity, a grow setup, which plants would work for what setup, and a multitude of other instructions usually including greenhouses. 'They' probably had success with their methods, and were likely trying to emulate the actual environments of the plants in-situ, and that was the prevalent methodology of the time. It sure makes logical sense that if they grow well in their indigenous habitat, if you re-create that, the plants should grow well.
But I decided that I really wanted to grow Nepenthes, and that I really wanted to have them as houseplants. I didn't want to spend the money on a fancy grow set up when I could use it to get more of the nice plants I wanted. And I knew if I tried to trade and people asked me what my grow setup was, and I answered 'on the back porch in the desert' I wouldn't have gotten people's precious babies, so I bought little starter plants back in the day to pour my own hard-earned money into the Grande Experiment. There were a couple people who were obvious renegades at the time, and growing their plants not in fancy terrariums, so I decided I'd give it a shot. I modeled my collection pretty early on based on the recommendations given by Nepenthes around the House, and got some inspiration from elgecko's magical window too. My conditions are mostly outside on a balcony in San Diego (close to Nepenthes around the House conditions), and some plants behind my windows inside (elgecko).
It was trial and error - I shipped off more than my fair share of plants that weren't doing well, and unfortunately killed a few on the way. Luckily they were clones, so I don't feel too guilty, but it would have been nice had I figured out how to grow N.campanulata. Along the way I added some other things to the collection including a few Sarrs, a pile of Helis at one time, Cephs, Dews, VFTs, and even some Utrics. Oh, and the hated Pings (slimy lettuce!).
Conditions are pretty bad here for swamp plants. My plants look terrible in comparison to other people's who actually have nice lights on auto-timers and consistent humidies >30% and consistent temps too. Huge pitchers, green leaves, and nice fluffy moss would be so nice! But I like the plants, so I keep trying to grow them and in the very least my collection can be an absurd testament to how much abuse the plants will actually take and still be able to thrive, to prove that other end of the spectrum from in-situ conditions.
Humidity swings can go from 100% to 0% in the span of a day or two, temps can be 65ºF one day and 100ºF the next day, and light levels are absurd (burning summer desert sunshine) and burn the plants' leaves when I first get them from other growers. I need to acclimate plants in baggies to indoor conditions let alone to go out on the balcony. When I get plants from Germany, that's easily a month with the bag method to acclimate them to the terrible conditions here, and often times more. When I used to get plants from Tony, his were the hardest and those I still precautionarily put in a bag for a week or two and suffered pitcher loss.
At the moment, I have all of my plants in a ~1/2 sphag moss mixture, sitting in saucers of water outside (water til they're sitting in water), except for the Cephs, Dews and Sarras (those are in half peat mixture). I water once a week, maybe twice if it's especially hot or windy. I have them in off-white plastic pots to reflect the heat of the sun, and am relying on evaporative cooling too. I'm not going past 8" pots because I don't have the space for that. Indoors, half sphag mix too and watering once a week because I don't have wind to evaporate the water away. I'm pretty afraid of root rot, so I keep my plants a lot dryer than I've ever seen anyone else grow theirs, although I had the Heliamphora all but swimming in their little pots of sphag back when I grew them outside. Heliamphora will survive 90ºF in the direct sunshine in a terrarium filled with sopping wet Sphagnum I've figured out. But, on the flip side, I don't think N.aristolochioides likes direct sunshine and did vastly better in the shade of a N.platychila vine.
