Hello,
I'm a long time Nepenthes grower but am recently struggling a bit to get the right conditions for my plants after switching to some more powerful lights (the old one broke). Some of my plants that were closer to intermediate than lowland died, and some others are suffering - slow growth, yellow leaves.
I'm not sure if the problem is having too much light (4 x 54w T5HO bulbs) or the heat they generate. I have put spacers between the terrarium and the lid to help bring the temps down, but have not yet changed the amount of time the lights are on. They come on at sunrise and turn off at sunset, so about 14 hours currently. I also added a fan on top of the hottest part of the lights to blow the heat away from the terrarium. Those changes resulted in the day time temps from peaking at 86-87F to 82-83F. The lows are a little more erratic but are close to 70-71. Humidity is at least 70% at night, and at least 60% during the day.
Does that sound pretty reasonable? You can see graphs of the temperature and humidity here if you are interested: https://my.wirelesstag.net/eth/tempStats.html?81d9ea5d-5989-4bff-b080-566ae909c240&Terrarium&F
According to this chart, most of my plants are ultralowland, lowland, or lowlands hybridized with intermediate. If it helps I currently have N. ampullaria, bicalcarata, albomarginata, ventricosa x mira, ventricosa x ovata, a plant I am wildly guessing is ampullaria x rafflesiana and a veitchii.
Thanks in advance for the help, let me know if pictures would help.
